Two Auburn men have been charged with organising drugs premises as part of an investigation into the supply of methamphetamine from Auburn.
Police also alleged they were Brothers 4 Life members.
The investigation began with officers from Wetherill Park Region Enforcement Squad, last December.
On Wednesday, police raided five homes in south-western Sydney, arresting the two men from Auburn and seizing cash, ammunition and drug equipment.
The men, both 20, were charged with supplying drugs, organising drugs premises and knowingly participating in a criminal enterprise.
They appear in Burwood Local Court this week.
Police also arrested a third man, aged 29, who is assisting them with their inquiries.
Police said they expected to make more arrests.
