The AFL and NRL finals have been thrown into chaos, with tens of thousands of fans unable to purchase tickets after the Ticketek website crashed.
A high demand for tickets for the two NRL semifinals, the AFL preliminary finals and country singer Luke Combs's upcoming tour, which all went on sale at 10am Monday morning, left many fans locked out after queuing on the site for hours.
Customers vented their frustrations over social media after being continuously re-routed to an error page.
Available tickets for Saturday's AFL preliminary final between Sydney and Collingwood have already sold out, with more tickets to be released on Thursday.
The supporter tickets for all four clubs in action in this week's NRL semifinals have also been exhausted.
Despite the drama, bumper crowds are expected for all four matches.
