National Basketball League (Australia)

• 1. Introduction

  ›

  The National Basketball League of Australia began life not as the NBL at all, but as something called the National Invitation Basketball League, a name that would not survive even its first full year. Founded in 1978 and kicking off its first season in 1979, the league was rebranded the NBL by 1980. What followed over the next four-plus decades was a story of golden eras and near-collapse, of ownership rescues and record crowds, of American imports who eventually became Australian citizens and played for the national team.

  At its lowest points, the league lost franchises from Sydney, Melbourne, Brisbane, and Singapore in a single two-year span. At its highest, over one million fans attended games in a single season for the first time since 1996. A broadcast deal with Facebook Watch drew more than one million American viewers for a single game featuring a teenage prospect named LaMelo Ball. And on the 11th of March 2025, the NBA and the Victorian State Government announced that the New Orleans Pelicans would bring NBA basketball to Rod Laver Arena in Melbourne, a first for the entire continent.

  To understand how a competition that once played 40-minute games with no three-point line became Australasia's premier professional basketball league, you have to follow the thread from a scrappy winter competition through its golden age, its near-death, and its rebirth under a property developer who promised no club would ever fold again on his watch.

• 2. Winter to Summer

  ›

  From its first season in 1979 through to 1998, the NBL played its games in the Australian winter, running April through September. That calendar put it in direct competition with Australian rules football, rugby league, rugby union, and soccer, all of which commanded deep local loyalty and crowded the sports media landscape.

  The league's twentieth season, the 1998 campaign, was its last in the winter slot. The very next competition, the 1998-99 season, flipped to a summer schedule running October through April. The move was a deliberate attempt to sidestep the football codes and carve out space where the NBL could breathe.

  That shift placed the NBL in a peculiar position in the record books. Officially, the league ranks as Australia's third oldest continuing national sporting competition, sitting behind the domestic cricket competition, which first ran in 1892, and the Australian Football League, which began in 1897 under the name Victorian Football League before changing its name in 1990. Basketball arrived late to the national stage but adapted faster than most.

  The regular season now runs from September to February, with each team playing 33 games. The finals extend into March and April, culminating in the Championship grand final series. The format of the games themselves also evolved. From 1979 through 1983, the NBL played 40-minute contests split into two halves with no three-point line. A 48-minute, four-quarter format ran from 1984 through the 2008-09 season. Since 2009-10, the league has settled on 40-minute games with four 10-minute quarters, a format the competition calls the modern 40-minute era.

• 3. The Golden Age and Its Aftermath

  ›

  The NBL's "golden age" arrived in the late 1980s and early 1990s, a period when the sport commanded strong media attention, healthy attendance, and corporate backing. The Adelaide 36ers and Brisbane Bullets drove much of the drama during those years, meeting in consecutive grand finals in 1985 and 1986.

  The 1985 final was the last single-game Grand Final in NBL history. Brian Kerle's Bullets defeated the 36ers 121-95. The following year's rematch introduced a three-game series format and produced the kind of basketball that builds rivalries for generations. An Australian indoor sports attendance record of around 11,000 people packed the Brisbane Entertainment Centre for Game 1 of the 1986 series. Adelaide, who had gone 24-2 during the regular season, won that opener 122-119 in overtime. Brisbane responded by handing Adelaide its only home loss of the year in Game 2, 104-83. The 36ers, who had gone 13-0 at Apollo Stadium during the regular season, then claimed the championship with a 113-91 win in Game 3 on their home floor.

  Import players defined the matchups of that era. Adelaide's roster included Al Green, Mark Davis, Bill Jones, Peter Ali, Darryl Pearce, Mike McKay, and Dwayne Nelson. Brisbane countered with star import Leroy Loggins, captain Larry Sengstock, guard Ron Radliff, forwards Danny Morseu, Robert Sibley, and Chris McGraw, centre John Dorge, and Cal Bruton. Loggins won NBL MVP honours in both 1986 and 1987. Mark Davis took Grand Final MVP in 1986 and shared the league MVP with Loggins in 1987.

  The decade that followed the golden age brought contraction instead of growth. The four football codes kept expanding their reach, and attendance, media coverage, and corporate support for the NBL plateaued and then declined. The league that had filled 11,000-seat arenas for a grand final would eventually lose teams from four cities in a turbulent two-year stretch around 2008 and 2009.

• 4. Collapse and Recovery

  ›

  By the mid-2000s, the NBL was experimenting with geographic reach that it could not sustain. The Singapore Slingers joined for the 2006-07 season, making the NBL the first Australasian sporting league to field a team from Asia. The South Dragons entered the competition that same season and lasted only three years before folding after winning the 2008-09 championship. The Gold Coast Blaze joined in 2007-08. Within two years, Sydney, Melbourne, Brisbane, and Singapore had all lost franchises.

  The 2009-10 season was marked as the beginning of a revamp. The league returned to free-to-air television for the first time in three years with the One network broadcasting two to three games per week. The Sydney Kings returned that season after the club had been purchased for 20,000 on the 31st of July 2008. Andrew Bogut, an Australian NBA player, had publicly suggested in 2007 that the NBL adopt a stable-franchise model similar to the AFL, with the same ten to fifteen teams locked in for a decade.

  The structural turnaround came when property developer Larry Kestelman purchased a 51% portion of the league. Crowds, television viewership, website visits, and app downloads began climbing consistently after that acquisition. In April 2016, the Townsville Crocodiles folded after becoming financially unsustainable, but Kestelman stated publicly, on the Aussie Hoopla podcast, that no NBL club would ever fold again as long as he remained in control.

  The league also introduced the marquee player rule on the 9th of May 2014, allowing teams to nominate one player whose salary sits outside the cap, subject to a 25% levy on payments above the cap threshold. NBL legend Andrew Gaze has pointed to these changes as instrumental to both the quality of imports and the development of Australian players. The Special Restricted Player rule, introduced for the 2016-17 season, added a further mechanism by allowing clubs to recruit players born in countries such as China, the Philippines, Taiwan, India, South Korea, Singapore, and Japan without those players counting against the standard import limit.

• 5. The Next Stars Pipeline

  ›

  On the 2nd of March 2018, the NBL announced the Next Stars initiative, which launched with the 2018-19 season. The program targeted young elite players, particularly Americans barred from the NBA draft until a year out of secondary school, giving them a professional option immediately after leaving school.

  Each club received one additional import roster slot for a Next Star player. The NBL contracted selected players directly, placed them in an allocation pool, and distributed them among teams. A Next Star's package included a salary of at least 100,000, plus a car, apartment, and flights home during league breaks. For the first season, the NBL funded the program itself, meaning Next Stars did not count against any team's salary cap. If an NBA team later bought a player out of their Next Star contract, the buyout amount would be split between the club and the league. Under current NBA rules, NBA teams can spend up to 700,000 to buy players out of professional contracts in non-North American leagues.

  American Brian Bowen was the first player signed to a Next Star contract, on the 7th of August 2018, and was assigned to the Sydney Kings. The program's most dramatic proof of concept came in the 2019-20 season, when LaMelo Ball and R.J. Hampton, both highly rated prospects for the 2020 NBA draft, signed with NBL clubs. The opening night of that season drew 10,300 fans to watch Melbourne United face the S.E. Melbourne Phoenix. A further 20,550 fans attended games across the first round. After the league signed a broadcasting deal with Facebook Watch, over one million American viewers watched Ball's debut game against the Brisbane Bullets.

  As of July 2024, three Next Stars players had become top ten NBA draft picks: LaMelo Ball, taken third in 2020; Josh Giddey, taken sixth in 2021; and Alex Sarr, taken second in 2024. The 2024 NBA draft also saw four Next Stars players drafted in total. That same year, in April 2024, the NBL appointed NBA legend Kenny Smith as Head of Next Stars' Player Initiatives for North America. In June 2024, Carmelo Anthony joined as a Global Ambassador and also joined the ownership group of a future NBL expansion team.

• 6. Rivalries That Shaped the League

  ›

  The rivalry between the Adelaide 36ers and the Perth Wildcats stands as arguably the most statistically rich in NBL history. As of the 15th of November 2019, the two clubs had met 134 times in total, with Perth leading the all-time head-to-head 73-61. On the all-time wins list as of the 20th of May 2021, Perth led with 748 wins and Adelaide sat second with 692.

  For years, the intensity of their clashes did not produce a grand final matchup. The teams met in semi-final series in 1987, 1989, and 1995, with the Wildcats winning each. It was not until the 2013-14 season that they finally faced each other in a grand final, which Perth won 2-1 to claim their record sixth NBL championship. Adelaide and Perth now compete for the Cattalini Cup, named for Martin Cattalini, a Perth-born player who won two championships with each club. The game MVP in those matchups receives the Paul Rogers Medal, named for an Adelaide-born centre who joined Perth and won the league MVP award in 2000.

  The 1995 semi-final series added a particularly violent chapter to the Adelaide-Perth story. Under instructions from coach Mike Dunlap to physically confront Perth players driving through the key, 36ers forward Chris Blakemore backhanded Wildcats forward Martin Cattalini in Game 1, opening a cut that required 15 stitches. Blakemore was suspended for Game 2. Perth swept the series 2-0. Blakemore had won the NBL Rookie of the Year award in 1993 and Most Improved Player in 1994 and represented the Australian Boomers in 1995, but his career declined sharply afterward.

  Melbourne's own intra-city rivalry, known as the Throwdown, began on the opening night of the 2019-20 season when the S.E. Melbourne Phoenix beat Melbourne United 91-88 in the Phoenix's very first NBL game. The two clubs share John Cain Arena, which holds 10,300 people. When a rivalry shares a building, the needle finds a sharper edge.

• 7. Records and Honours

  ›

  Perth has won more NBL championships than any other club, with ten titles. Melbourne United and the Sydney Kings each hold six. The Perth Wildcats and the New Zealand Breakers dominated the competition together for an eight-year stretch, with one of the two clubs winning the championship every season from 2009-10 through 2016-17.

  The Illawarra Hawks are the only club to have participated in every NBL season since the inaugural 1979 competition. The Brisbane Bullets and the Hawks are the two oldest clubs in the current league, both established in 1979. The Tasmania JackJumpers, the newest franchise, joined for 2021-22 and won their first championship in 2024.

  The NBL Hall of Fame was instituted in 1998 as part of the league's twentieth-season celebrations. In 2010, it merged with the Basketball Australia Hall of Fame to create the Australian Basketball Hall of Fame. Andrew Gaze anchored every anniversary team the league has assembled. In the 25th Anniversary voting in 2003, Gaze received 287 votes from a 32-member selection committee, the highest total of any player. He was also named the 25th Anniversary Most Valuable Player. Leroy Loggins placed second in that poll with 255 votes. When over 6,000 fans voted in the 40th Anniversary process in 2018, Gaze and Mark Bradtke drew the most support from the public.

  On the broadcasting front, the league and ESPN announced on the 20th of August 2025 an extended deal covering the 2025-26 season, with games running live on Disney+ via the ESPN tile alongside existing coverage through Foxtel, Kayo Sports, Fetch TV, and Sky New Zealand. In January 2024, the NBL also announced a partnership with Japan's B.League, exploring pre-season crossovers and the potential for a Japanese team to join the competition, a move that would extend the league's geographic reach to its third Asian market.
