St Kilda CEO Simon Lethlean has urged fans to do better in the wake of reports Western Bulldogs player Jamarra Ugle-Hagan was racially abused by a Saints fan on Saturday night, nearly three decades after Nicky Winmar made his own statement against racism while playing for the club.

Both the Saints and Bulldogs confirmed late on Sunday that they had been made aware of allegations over a comment made towards Ugle-Hagan, with both clubs and the AFL quickly condemning the act.

Lethlean confirmed the club had spoken to the Bulldogs and was working to identify the supporter, confirming that if that person was a club member, they would have their membership revoked.

"It's disgraceful behaviour, it's just not to be tolerated on-field or off-field," Lethlean told gathered media on Monday.

"We'll do all that's in our power to find out who that was in the crowd. The allegations of what was said was totally inappropriate and if we can find who it was they're not welcome at our games.

"First thing is to find them, speak to them, educate them and they're not coming back to St Kilda games any time soon.

"It's 30 years and two weeks since Nicky Winmar made (his) statement ... to still be dealing with stuff like this now is completely inappropriate.

"They're entitled to have a safe workplace, our Indigenous players and our multicultural players. If it isn't the case, it has to improve."

Lethlean, a former executive at the AFL, conceded the game has a long way to go but encouraged education around the league.

"We encourage all fans to call out this behaviour, to stop it, to teach your kids what is right," he said.

"Yeah, you certainly despair - 30 years ago, on April 17, Nicky did what he did because he didn't feel safe and feel respected. It's still happening.

"All we can do is call it out, educate, support our people and hope that it stops. That's obviously a work in progress."

Stand-in Saints skipper Callum Wilkie also expressed his disappointment in the incident, echoing Lethlean's call for more education around the topic.

"You know, it's not good enough, especially from one of our fans and anyone in society. Indigenous players have done so much for our game and so much for our football club," Wilkie said.

"We've had so many greats throughout our history and who are with us now and you know, we feel for them whenever all when it happens.

"It keeps happening and it's not good enough and we'll fully support our Indigenous players and fully support Jamarra.

"There needs to be more education around it. Really disappointed that's come from one of our fans, and especially with how great indigenous players have been for St Kilda."
