BIG Day Out promoter AJ Maddah has today confirmed that Sunday's festival would be the final time the event returns to Perth.

Taking to Twitter to field questions about yesterday's statement that that Sunday was "definitely the last BDO for Perth.", Maddah tweeted "It wont come back to Perth. Ever.".

After quashing hope that the festival might return in the future, Maddah also denied that Big Day Out CEO Adam Zammit had contradicted his statements, despite media reports claiming otherwise.

"He didn't say otherwise," Maddah tweeted.

The CEO then joined the Twitter conversation writing "AJ's decision was wholeheartedly supported by everyone at BDO. #factstraight".

The fate of another summer festival, Soundwave, remains uncertain, with Mr Maddah saying he wasn't sure if that event would be back in Perth next year.

This weekend's festival - to be headlined by international acts Pearl Jam and Arcade Fire - will be Perth's 22nd Big Day Out.

@KayleeRace1 Not sure. Definitely the last BDO for Perth.

Mr Maddah has been reported as saying the fate of festivals in Perth rested on support from local and state governments, rather than ticket sales.

"I reckon there will be zero festivals going to WA in 2015," several music websites quoted Mr Maddah as saying last week.

The Perth event was scaled back in 2012 and this year it will be held at Arena Joondalup for the first - and last time.

The annual event, which had its long-term home at the Claremont Showground, had faced ongoing problems with the Town of Claremont in recent years.

In other music festival news, Stone Temple Pilots have pulled out of the Soundwave Festival, which will be held at Arena Joondalup on March 3.

The band was among the headline acts and is blaming the cancellation on changes in the recording schedule of their new album.

They will be replaced by The Living End.

"The recording of the new album has now gone beyond schedule and sadly the availability of the recording studio, engineers and the producer or lack thereof dictates that the band have had to cancel their upcoming engagements," a statement from Stone Temple Pilots reads.

PerthNow has been unable to reach other Big Day Out and Soundwave promoters for comment.

@KayleeRace1@pippa_reed@Atkinson_Tom Nope. It wont come back to Perth. Ever.
