SEABL/NBL1
In 1990, with the Eastside Spectres still a championship contender in the NBL, a Nunawading Spectres men's team re-emerged in the form of a South East Australian Basketball League (SEABL) franchise. In 1992, a Spectres women's team debuted in the SEABL.[6]
In 1995, the men's team collected their first title as they won the SEABL East Conference championship. The women's team were SEABL runners-up in both 2000 and 2008, while the men were conference runners-up in 1999 and 2004.[6]
In 2011, the men's team won their second conference title and their first SEABL championship after defeating the Bendigo Braves 88–61 in the grand final. Spectres guard Shane McDonald had a game-high 28 points to earn the MVP award.[7][8]
After finishing as conference runners-up in 2013,[9] the men's team won their third conference title in 2014 behind the likes of Mitch Creek, Tommy Greer, Shane McDonald, Simon Conn and Matt O'Hea.[10] They went on to lose 85–71 in the SEABL grand final to the Mount Gambier Pioneers.[11]
In 2018, the Spectres men finished as SEABL runners-up after losing in the grand final to the Hobart Chargers.[12]
In 2019, following the demise of the SEABL, the Spectres joined the NBL1.[13] The men went on to win the championship with a 99–90 win over the Bendigo Braves in the grand final.[14][15][16] The NBL1 South season did not go ahead in 2020 due to the COVID-19 pandemic.[17]
