Yarra Trams is looking into an alleged racist incident on a tram on Wednesday night.

Melbourne-based transport blogger Marcus Wong said he had a confrontation with a burly man who was allegedly making racist comments on a packed route 57 tram as it stopped outside Queen Victoria Market about 7.30pm.

This tram passenger is accused of making racist comments.

Mr Wong said as a group of passengers spoke to each other in a foreign language, the man muttered to his girlfriend in reference to them: "You're in Australia: Speak English."

Mr Wong, 27, said he verbally confronted the man and was then abused by him.
