Metallica have broken Australian ticket sales records with their 20-date tour in the region.

The metal icons sold out four shows at the Sydney Acer Arena, marking a total of 74,244 tickets sold. This breaks the record set by Britney Spears' 2009 "Circus" tour, which sold 66,247 tickets.

"It was a massive, awesome performance," Acer Arena GM Paul Sergeant tells "Even if you weren't a Metallica follower, you'd have enjoyed that show. It was huge."

Michael Coppel, Metallica's Australian promoter added, "It's a fantastic tribute to Metallica, as they approach 25 years since their first Australian tour, that they enjoy such an incredible level of support."

The tour, Metallica's first in Australia since 2004, kicked off on September 15 in Melbourne. It included dates in Sydney, Brisbane, Perth, and Adelaide with additional shows in Christchurch and Auckland, New Zealand. The tour wrapped up on November 21.
