A set of triplets and their father have been granted bail over a brawl with police in Sydney's south-west yesterday.

Seven police were injured in the brawl with the Mehanna family outside their home at Bankstown early on Wednesday.

Police say the officers were bitten, punched and concussed, and dozens of police had to be called in to break up the fight.

Two family members also suffered minor injuries.

About a dozen family and friends gathered in Parramatta Bail Court this morning, some of them wiping away tears, as Mohammed Mehanna, his triplet sons, and his daughter appeared on charges of assaulting police, affray and resisting arrest.

Police did not oppose bail and it was granted.

Another son is yet to face court today.

His mother has been ordered to appear in court on similar charges next month.
