While attempting to joke with his audience, Thomas made a shocking comment, which has since led to allegations of racism.

Online, fans have taken to social media, where they've deemed Thomas' comments "racist" and "ignorant."

Australian writer Carly Findlay, who was in attendance during Thomas' show, shared a Facebook message with fans afterwards, explaining, "This has disappointed me incredibly. He's a good guy--a caring husband, animal rescuer, beautiful writer, seasoned performer, and regular visitor here. That's why I'm so shocked. I hope during his tour, Rob Thomas can meet with an Aboriginal community, apologise for his racism and learn--so his knowledge and perceptions about black Australia can be rectified."

In response to the controversy, Thomas released a statement of apology on Facebook.

"Please understand that I did not intend to make a joke ABOUT race. I have seen people comment that after coming here for so long I should know that there is a connection between the indigenous peoples of Australia and a stereotype involving drinking. Embarrassingly, I truly didn’t," Thomas wrote.
