Australian thrash fans are about to get flattened by a lineup that feels ripped straight out of a tape trading fever dream.
US thrash veterans Flotsam and Jetsam are finally heading down under for their first ever Australian run, joining forces with local legends Mortal Sin for a co headline tour this September and October.
Dubbed Monsters Of Thrash, the tour throws together two bands that helped shape different corners of the genre across four decades of riffs, speed and absolute neck destruction, add South Australian thrash machine Hidden Intent and Sydney speed metal crew Livewire into the mix, and this thing starts looking dangerously stacked.

Flotsam and Jetsam’s arrival in Australia has been a long time coming, the Arizona outfit have spent more than 40 years carving out their reputation alongside names like Metallica, Slayer, Megadeth and Venom, while somehow still feeling criminally underrated in broader metal conversations.
Their debut album, Doomsday For The Deceiver, famously scored the only 6K rating in Kerrang! history, and the band’s modern-era run has been just as relentless.
They’ll hit Australia armed with a new record too. Rats In The Temple lands August 28th via Napalm Records, with vocalist Eric ‘A.K.’ Knutson already calling it ‘our best effort to date’, if recent albums like The End Of Chaos and Blood In The Water are anything to go by, fans should expect razorwire riffs and enough double kick punishment to rearrange internal organs.
Meanwhile, Mortal Sin continue proving why they remain one of Australia’s most important thrash exports. Their recent return has already taken them through European festival stages including Keep It True, Alcatraz and Brutal Assault, and now they’re bringing that momentum back home beside one of American thrash’s most enduring names.
