Parkway Drive have officially cancelled their Viva The Underdogs Australian Revolution tour.

Originally scheduled to embark on their biggest tour of the country to date last June, the Byron Bay metalcore heavyweights then rescheduled to this July, however those plans are now scrapped.

"It’s with a heavy heart that we have to announce our Viva The Underdogs Australian Revolution this July is cancelled," the band said today.

"As venue restrictions, travel restrictions and government limitations on mass gatherings are still in place, the massive arena shows we had planned cannot go ahead in their current form.

"We would have loved to bring our full production show to Australia, but unfortunately this is not viable.

"Furthermore, our international friends in Hatebreed and Every Time I Die are also not allowed into the country, so we have made the regretful decision to pull the pin.

"The safety of our fans and delivering the full Parkway Drive experience is of utmost importance to us but we are confident we will see you all in 2022!"

Tickets can be refunded from the point of purchase. Fans will also be eligible for a 20% discount on Parkway Drive merchandise with a dedicated discount code being sent to all ticket holders.
