Fontaines D.C., Hayley Williams and This Is Lorelei may be heading Down Under for Laneway Festival 2027, if an apparent accidental poster leak is anything to go by.

A poster reportedly shared to LinkedIn by a designer — and later shared to Reddit — advertised Fontaines D.C. at Perth’s RAC Arena on Wednesday, February 17th, 2027, with Paramore frontwoman Hayley Williams and This Is Lorelei listed as support.

The LinkedIn Post was subsequently removed, but not before the screenshot made its way to Reddit, where users quickly began connecting the dots. The original post discussing the apparent leak was also taken down after the Redditor was asked to remove it, although the thread remains active.

Adding fuel to the speculation, users noted that the artwork appeared to feature Laneway Presents and Handsome Tours branding.

The alleged Perth date falls neatly between Laneway Festival’s already-announced 2027 stops. The festival will hit Sydney’s Centennial Park on Friday, February 12th, followed by Brisbane Showgrounds on Saturday, February 13th. After a four-day gap, during which the rumoured RAC Arena show would take place on February 17th, Laneway continues to Melbourne on Friday, February 19th and Auckland on Sunday, February 21st.

There is currently space in the artists’ announced touring schedules for an Australian run during that period.

Williams’ currently listed 2027 headline dates finish in Mexico on January 17th before resuming in Europe in June, while This Is Lorelai is booked to play Amsterdam on February 24th.

There is also already a connection between Williams and Fontaines D.C. — she is confirmed as a special guest at the Irish band’s two massive Slane Castle shows in June 2027, alongside Damien Dempsey and Madra Salach.

None of the three artists have officially been announced for Laneway Festival, and the Perth show itself remains unconfirmed.

Laneway has previously revealed that its full 2027 lineup will be announced in late September, meaning fans won’t have too long to find out whether someone just spoiled part of the surprise.
