A young Aboriginal man has published screenshots of racist slurs he was subjected to on a gay dating app in a bid to draw attention to discrimination in the gay community.

Medical student Dustin Mangatjay McGregor said he regularly received racist abuse from potential dates on Grindr, including being called a "petrol sniffer" and a "wog abo c***".

Mr McGregor said gay men who were not white were more likely to be rejected in the online dating world and that he was fed up with users disclosing their racial preferences in derogatory terms, such as "no rice or spice", meaning they have no interest in Asian or Indian men.

"There's a hierarchy in the gay community," said Mr McGregor, who is from North East Arnhem Land and also has Greek and Scottish heritage.
