South Australian authorities are warning race fans to be on high alert after a fraudulent website surfaced posing as the official ticket vendor for the state's upcoming MotoGP event, Yahoo News Australia reports.

"It is very concerning that this page purporting to be an official MotoGP Adelaide website and containing misinformation and AI content is circulating on social media," said Michael Brown, South Australia's cabinet member for consumer and business affairs.

The illegitimate site, which features contact details with a Czechia area code and claims a company called TicketsGP is the official seller, is encouraging users to hand over personal information, according to the government.
