Two men trade punches as vicious brawl breaks out on Adelaide bus

An Aboriginal man has reportedly gone on an aggressive racist rant against fellow passengers on a bus, before punching an unsuspecting man in the head.
The incident, believed to have occurred in Adelaide, South Australia, last month, was filmed by a commuter of the bus and has since been posted online to YouTube.
After calling for 'everyone to leave Australia', the footage shows the Aboriginal man abusing a passenger before walking over and punching him in the back of the head.
Heard calling the man a 'motherf****r b***h', the aggressor can then be seen rising from his chair before hitting the unsuspecting man in the back of the head.
A struggle between the men then ensues, with the pair grappling at each other and falling onto a chair of the bus where a woman is sitting.
The other man, who is identified as Indian by the individual with the camera, landed a number of punches on the Aboriginal man.
As horrified passengers look on, one can be heard calling for the 'naughty boys to stop'.Forced to be separated by male passengers, the Aboriginal man returns to his seat.
Dressed in a pair of camouflage pants, a dark t-shirt, a cap and with a backpack on his back, he was soon lectured by a fellow passenger.
'You see my friend, you start the fight you get bashed,' the man, who is seemingly taking the video, says.
Looking downcast, the Aboriginal man stares at the ground before spitting on his hand.
After again being told off for starting the fight, the aggressive man lashes out and tells the man videoing to 'shut up', before the filming ends.
