It had been a chippy second half, but things truly boiled over when Filipino guard Roger Ray Pogoy bulldozed through his defender, Australia's Chris Goulding.
Australia big man Daniel Kickert retaliated by leveling Pogoy with an elbow to the face, precipitating an all-out brawl that featured several punches, flying kicks, a thrown chair and, eventually, 13 ejections.
In the end, a totoal of 13 players were ejected, nine from Gilas.
After 30 minutes of video review and discussions between officials from both nations the referees ejected Kickert, Maker, Goulding and Sobey then also tossed out nine Philippines players, leaving just Gabe Norwood, Baser Amer and June Mar Fajardo left to play.
The incident started when a player for the Philippines decked an Australian with almost four minutes left in the third quarter.
The teams are competing in the Asian qualifiers for the 2019 FIBA World Cup. "The decisions will be communicated in the coming days", FIBA tweeted on Monday.
