The feud between Mount Isa AFL clubs Tigers and Lake Nash hit a tipping point on Saturday with their semi-final clash abandoned with ten minutes left on the clock.
Tigers were winning comfortably when multiple fights broke out on the field and the situation worsened when a spectator got involved.
The umpires immediately called the game off, and Tigers were declared the victors with score at 108-26.
Angry Lake Nash fans continued to protest for several minutes before police arrived to calm the situation.
The incident comes three weeks after "verbal abuse" led to complaints to AFL Queensland the last time the two clubs met.
Now AFL Queensland said the latest matter was being looked into.
"Both ourselves and AFL Mount Isa have been contacted regarding an incident involving players and spectators at the Preliminary Final game played between Lake Nash and the Mount Isa Tigers which resulted in the game being abandoned," an AFL Queensland spokesperson said.
"AFL Queensland and AFL Mount Isa are currently conducting an investigation into the incident."
Mount Isa Police Sergeant Whitney Lacy said that although concerning, no official complaints have been made to the police.
"Allegedly there were some hard hits and racial insults thrown around during the game," Sgt Lacy said.
"However, nil formal complaints have been made to police and nil enforcement action is needed to be taken."
Police attended to keep the peace and assist with the large crowds leaving the ground.
