A Greenslopes man alleges he was brutally bashed by his neighbour in a racial attack on Friday.

Rohan Sharma, 23, suffered a black eye and fractured nose in the fight which he claims began over a shared garage.

The university student told 9News he was on the phone to a friend when his neighbour started racially abusing him and his sister.

The matter has been referred to the police, who have been unable to comment on whether they have caught up with the pair.
