NBL1 Explained: Australia's Second Tier of Basketball

NBL1 is Australia's second tier of senior basketball. It sits directly below the NBL and the WNBL, it is semi-professional rather than fully paid, and it is organised into five regional conferences that between them cover every state and the Australian Capital Territory. Seventy-two clubs contest it, and every one of them fields a men's team and a women's team in the same competition.

The single most useful fact about NBL1 is its calendar. It plays through the Australian winter, from March to August, while the NBL plays from September to March. The two competitions barely overlap, which means a professional can finish an NBL season in February and sign with an NBL1 club in March. That is why the standard of the second tier is higher than the word semi-professional suggests, and it is why NBL1 functions as the country's basketball engine room rather than as a backwater.

This page covers what NBL1 is, how the five conferences are put together, what the season looks like, who plays in it and what sits above and below it. The clubs of the NBL and the NBL finals system are covered separately, as are junior representative basketball and community and social basketball, which are the two tiers underneath this one.

Where NBL1 sits in the pyramid

Australian basketball has a reasonably clean four-level structure, and NBL1 occupies the second rung. Above it are the two national professional competitions, the NBL for men and the WNBL for women, both playing across the summer. NBL1 is next. Below NBL1 sit the state leagues, which vary in name and shape by jurisdiction. Below those are local association competitions, where the overwhelming majority of Australians who play basketball actually play.

The pyramid is not connected by promotion and relegation at any point. A club moves up by applying for and being granted a licence, not by winning something. That makes NBL1 structurally similar to the closed competitions above it and structurally different from the promotion and relegation debate that runs through Australian football.

What makes NBL1 unusual for a second tier anywhere in Australian sport is that its clubs are independent. They are not reserve teams. A club like Eltham Wildcats or Warwick Senators is a community basketball association with hundreds of junior teams, a stadium, a membership and a history of its own, and its NBL1 side is the top of that association rather than the bottom of somebody else's.

The five conferences

NBL1 is not one national ladder. It is five separate competitions run by five state bodies under a shared brand, playing to a shared calendar and converging once a year at the National Finals.

Conference	Territory covered	Clubs	2026 mens champion	2026 womens champion
NBL1 South	Victoria, Tasmania, part of South Australia	19	Frankston Blues	Knox Raiders
NBL1 East	New South Wales and the ACT	16	Norths Bears	Bankstown Bruins
NBL1 West	Western Australia	14	Rockingham Flames	Warwick Senators
NBL1 North	Queensland	13	Gold Coast Rollers	Mackay Meteorettes
NBL1 Central	South Australia	10	Forestville Eagles	Sturt Sabres

The distribution follows basketball's actual footprint rather than population alone. Victoria has the deepest club system in the country, which is why South is nearly twice the size of Central. Queensland's clubs are spread across enormous distances, from the Gold Coast to Cairns, and travel is a real cost line in a North club's budget in a way it is not for a Melbourne club whose furthest away game is an hour on the ring road.

How NBL1 was assembled

NBL1 did not invent Australian second-tier basketball, it consolidated it. Before 2019 the tier below the NBL was a patchwork of state and regional leagues with no relationship to each other, no shared brand and no national title.

The trigger was the collapse of the South East Australian Basketball League after the 2018 season. SEABL had been the strongest of the second-tier leagues, spanning Victoria, New South Wales, the ACT and Tasmania, and its failure left a large hole. Basketball Victoria partnered with the NBL to launch NBL1 in 2019 as its replacement, initially as a single competition of Victorian, Tasmanian and South Australian clubs.

The rest followed quickly. The Queensland Basketball League and the South Australian Premier League were folded in as the North and Central conferences, though the 2020 season was cancelled before it began because of the pandemic and those conferences first played in 2021. Western Australia's State Basketball League became NBL1 West in 2021. New South Wales and the ACT's Waratah League became NBL1 East in 2022. A Darwin club represented the Northern Territory in the North conference for three seasons before withdrawing after 2024.

Six years is not long, and it is worth remembering how recent the current shape is. Most of the clubs are decades older than the competition they play in.

The winter calendar and why it matters

NBL1 plays from late March to mid-August. The 2026 conference seasons ran 21 March to 16 August, with finals through August and the National Finals from 21 to 23 August.

This puts NBL1 in direct competition for attention with the AFL and the NRL, which is a difficult market position. It also puts it in exactly the right slot for the sport. The NBL and the WNBL play in summer, so their players and their listed development players are free from March. Australians on college or European contracts are also free in the middle of the year. A winter league can sign all of them, and a summer league could not.

The trade-off is visibility. NBL1 grand finals are played in August, in the same weeks as AFL and NRL finals, and the competition simply cannot buy back page space in that window. The league accepts that because the alternative is competing with the NBL for players, which would be worse.

What a conference season looks like

Each conference sets its own fixture length, which is one reason NBL1 can be confusing to newcomers. A South club plays a different number of games from a Central club. What is consistent is the shape.

Clubs play a home and away regular season through autumn and winter, almost always as double-headers where the women's team plays first and the men's team follows at the same venue on the same night. That format is the norm rather than the exception and it is worth stating plainly, because in most Australian sports the women's competition runs on a separate calendar with separate fixtures.

Conference finals follow in August. The formats differ: South has run a ten-team series across four weekends, West and East have used eight-team formats, and North and Central have used shorter best-of series. Grand finals are often moved to a larger venue than a club stadium, with recent conference deciders played at Adelaide Entertainment Centre and RAC Arena.

The sequence of a single NBL1 year. Fixture lengths and finals formats differ by conference, so this describes the shape rather than a fixed number of games.

The NBL1 National Finals

The National Finals are the one point in the year when the five conferences meet. They were first played in 2022, three seasons after the competition launched, and they are the only reason NBL1 can be described as a national league rather than five regional ones.

The format is compact. Six men's teams and six women's teams travel: the five conference champions in each competition plus the reigning national champion from the previous year, who is granted a place regardless of how their season went. The whole thing is decided over three days.

The 2026 edition was held in Adelaide from 21 to 23 August, at the State Basketball Centre at the Adelaide Showground, with more than 120 players and coaches travelling. Gold Coast Rollers took the men's title, beating Forestville Eagles 70-67 in overtime. Knox Raiders won the women's, beating Bankstown Bruins 86-73. Knox have been the most consistent presence at the event since it began.

Who actually plays in NBL1

An NBL1 roster is a mix of four groups, and understanding the mix explains the standard.

The first group is imports, mostly American, usually recent college graduates, limited in number by conference rules. The second is professionals from the NBL and WNBL filling their off-season, either established players keeping match fitness or development players who need minutes they are not getting in summer. The third is Australians who have returned from college or an overseas contract. The fourth, and the largest, is local players who came through the club's own junior program and now play semi-professionally while working or studying.

That last group is what keeps NBL1 anchored to its associations. A Victorian club's NBL1 team is frequently full of players who were in that club's under-14s a decade earlier, and the crowd knows it.

Imports and the player points system

Every conference restricts imports and every conference runs some version of a player points system. The mechanism is the same across the country even though the numbers are not.

Each player is assigned a points value according to category. An import carries the highest value. A player with recent NBL or WNBL starting minutes carries a high value. Local juniors and long-serving club players carry low values, sometimes with a discount for loyalty or for having come through the club's own junior system. A squad's total points cannot exceed a cap, and the number of high-value players one club can hold at once is separately limited.

The purpose is competitive balance without a cash salary cap that would be impossible to audit across 72 community clubs. Rather than policing what clubs pay, the conferences police what clubs can field. The specific values are published each season in each conference's rules of operation and are revised regularly, so anyone who needs the current numbers should read their own conference's document rather than trusting a figure quoted online.

NBL1 South

South is the original conference and the biggest, with 19 clubs across Victoria, Tasmania and Mount Gambier in South Australia. It is the direct successor to SEABL and it contains the deepest concentration of basketball clubs anywhere in Australia, most of them in Melbourne's suburbs.

Several South clubs joined from the Big V, Victoria's state league, when NBL1 launched. Names like Eltham Wildcats, Knox Raiders, Ringwood Hawks and Waverley Falcons are among the best known association brands in the country, each attached to a stadium and a junior program of substantial size.

Tasmania is represented through Hobart and Launceston, which adds a genuine travel burden to a conference that is otherwise geographically tight.

NBL1 East

East covers New South Wales and the Australian Capital Territory with 16 men's and 16 women's teams. It was formed from the Waratah League in 2022, the last of the five conferences to come in, and the Waratah League continues underneath it as the state's senior competition.

East is the conference with the Centre of Excellence team in it, which makes its fixture list unusual. It also holds clubs with strong crossover into the professional game, and the pattern of professional clubs sharing a region with an NBL1 club is more common here than elsewhere.

Canberra Gunners have been a significant presence, arriving as reigning national champions at the 2026 National Finals.

NBL1 North

North is the Queensland conference, 13 clubs strung along a coastline that runs from the Gold Coast to Cairns. It came out of the Queensland Basketball League and it carries the heaviest travel load of the five conferences by a wide margin.

Far north Queensland clubs in Cairns, Townsville and Mackay have to fly, and a road trip in this conference is not a metaphor. That geography shapes fixture design and it shapes budgets, because travel is a much larger share of a North club's costs than a South club's.

Gold Coast Rollers won the men's national title in 2026 and Mackay Meteorettes took the women's conference championship, which is a fair illustration of how spread the strength is.

NBL1 West

West is Western Australia's conference, 14 clubs, built on the former State Basketball League. It is the most self-contained of the five: no other conference has less contact with the rest of the country during the regular season, and Perth's clubs play almost exclusively against each other, with Geraldton the notable exception.

The SBL was a strong league before NBL1 absorbed it, with a long tradition and a settled club structure, and West retains a distinct identity within the national brand. Its grand finals have been played at RAC Arena, the same building the Perth Wildcats use.

Rockingham Flames and Warwick Senators took the 2026 conference titles.

NBL1 Central

Central is South Australia's conference and the smallest at 10 clubs, formed from the South Australian Premier League. Being small has an advantage: the fixture is tight, clubs know each other well, and the rivalries are old.

Central's grand finals return to the Adelaide Entertainment Centre, a genuinely large venue for a semi-professional competition, and the state hosted the 2026 National Finals. Forestville Eagles and Sturt Sabres won the 2026 conference titles, and Forestville went on to lose the national men's decider in overtime.

The overlap with NBL1 South is a quirk worth knowing: Mount Gambier plays in South rather than Central, because of geography rather than politics.

What sits below NBL1

Each state keeps a senior competition below its NBL1 conference. In Victoria that is the Big V, which runs multiple divisions for men and women and functions as the tier from which several current NBL1 clubs were drawn. In New South Wales the Waratah League continues under NBL1 East. Other states run equivalent competitions under their own names.

These leagues are not feeders in the formal sense, because there is no promotion. They are where a club without an NBL1 licence plays senior representative basketball, and where an NBL1 club can field a second team to develop players who are not ready for the top squad.

Below that sits local association basketball, which is a different animal entirely and is covered on the domestic and social basketball page.

How clubs get an NBL1 licence

Licences are granted by the conference, and the criteria are administrative rather than sporting. A club needs a compliant home venue, evidence of financial capacity to run two senior teams for a full season, a junior program that justifies the position, and the governance to satisfy a state body.

That is a high bar for a community association and it is why the number of clubs moves slowly. It also means that a strong on-court season in the Big V or the Waratah League does not, on its own, earn anything. Clubs plan licence applications years ahead.

Licences can also be handed back, as happened when the Northern Territory's entry in the North conference withdrew after 2024. Small conferences shrink and grow at the edges.

The women's competition is not an afterthought

It is worth restating, because Australian sport gives few comparable examples. NBL1's men's and women's competitions are one competition. Same clubs, same fixture, same venues, same nights, same finals weekends, same National Finals.

The practical effect is that a women's NBL1 team has the full infrastructure of the association behind it rather than a share of a men's club's attention, and that women's games are played to a crowd that is already in the building rather than to whoever arrives early. It is a structural advantage that the women's competitions attached to the football codes do not have, and it is one reason WNBL players have a straightforward place to play in the winter.

What NBL1 pays

Payments vary enormously and are not published in the way an NBL salary cap is. The realistic picture is that imports and a small number of leading local players earn enough to live on for the season, often with accommodation and a car included, while the rest of a roster is paid modestly or not at all beyond expenses.

That is what semi-professional means in practice. Training is at night because players work during the day. Clubs are run by a small paid staff and a large volunteer base. Player payments compete for the same money as junior programs and stadium maintenance, which is a genuine tension inside a community association.

Anyone treating NBL1 as a career step should understand it as a place to be seen rather than a place to be paid.

Watching a game

NBL1 is one of the cheapest live sport tickets in the country. Entry to a regular home fixture is typically a small door charge, seating is unreserved, and the double-header means two full games for one admission.

Streaming covers most fixtures through the league's digital platforms and through conference and club channels, with production quality ranging from full commentary to a single fixed camera. Conference grand finals and the National Finals get proper broadcast treatment.

The venues are association stadiums with multiple courts rather than purpose-built arenas, and on a Saturday the NBL1 game is usually the last thing on after a full day of junior fixtures on the same floor, with the same volunteers running the scorebench all day and the same canteen open since eight in the morning. That is the texture of the competition, and it is quite different from an NBL night at a major arena.

How NBL1 feeds the professional game

There is no draft out of NBL1 and no formal transfer system. What exists is a scouting relationship, and it works in both directions.

Professional clubs watch NBL1 because it is the only place in the country where a large number of senior-standard Australians play competitive basketball at once, and because it runs exactly when professional lists are being built. A player who has a strong winter is being watched by people making decisions about the following summer. That is far more useful than a trial camp, because it is a full season of evidence against consistent opposition.

The traffic in the other direction is heavier still. Every summer, players who did not get a professional contract, or who were on a development contract with limited minutes, go back to an NBL1 club. Some of them are back in the NBL the following year. The absence of a formal mechanism is not a gap in the system, it is the system: the two calendars mean the same player can simply keep playing, and the market sorts itself out.

The one structural link that does exist is age-based rather than contractual. The Centre of Excellence team in the East conference is a deliberate placement of the national junior program into senior competition, and several NBL1 clubs run similar arrangements informally with their own top juniors.

Coaches and officials

NBL1 is as important a development tier for coaches and referees as it is for players, and this part of the competition is almost never discussed.

Head coaching an NBL1 club means running two training sessions a week with players who have day jobs, managing an import who has arrived from another continent, recruiting inside a points cap and doing all of it on a part-time salary. It is the closest thing to an apprenticeship for a professional head coaching job that Australia offers, and a large share of NBL and WNBL assistant coaches have done it.

Officiating follows the same logic. NBL1 games are the highest-level assignment most Australian referees will get before professional appointment, and the conferences run their own development panels. A referee who wants to work in the NBL will almost certainly spend several winters in NBL1 first, in front of small, close and extremely vocal crowds. Association stadiums are unforgiving rooms, and that is part of the training.

Both roles are heavily volunteer-supported below the top few appointments, which is a genuine constraint on how fast the competition can grow.

The brand and the money

NBL1 carries a naming rights sponsor, with Mitsubishi Motors Australia holding the rights since 2023 after Coles Express. That single national deal sits over the top of five conferences that otherwise sell their own sponsorship, and it is the most visible sign that NBL1 is a brand laid over pre-existing leagues rather than a company that owns them.

The economics underneath are modest. Individual clubs run on membership fees, canteen and bar takings, junior program revenue, local sponsorship and stadium hire, and the senior program competes for that money with everything else the association does. A good National Finals run costs a club money in travel before it earns any back.

That is the honest financial picture of Australia's second tier, and it is worth holding alongside the standard on court. NBL1 produces professional players and professional coaches on community budgets, which is impressive and also fragile.

NBL1 compared with other Australian second tiers

The comparison that clarifies NBL1 best is with the second tiers in other codes. The state leagues below the AFL and the NSW Cup and Queensland Cup in rugby league are, in large part, reserve competitions. Their fixtures exist partly to serve the clubs above them, and a significant share of their players are on top-flight lists.

NBL1 is not built that way. Its clubs answer to nobody above them. They existed first, they own their venues and juniors, and their relationship with the NBL is a supply relationship rather than an ownership one. That makes NBL1 closer in spirit to the National Premier Leagues in football or to the SANFL and WAFL at their most independent, and it explains why the competition is so much larger than a reserve-grade system would ever need to be.

What NBL1 is not

It is not a development league owned by the NBL, even though the NBL is a partner. It is not a national ladder, because the five conferences never play each other outside the National Finals. It is not a professional competition, and describing it as one oversells what most of its players earn. It is not a route with a guaranteed destination, because there is no draft from NBL1 into the NBL and no promotion into it.

What it is, accurately, is the largest serious basketball competition in Australia by club count, the place where almost every Australian professional has played at some point, and the layer that connects a very large community sport to a small professional one. More on the wider structure of the game sits on the Australian sport hub and the basketball section.
