Taylor Swift's The Eras Tour in Australia has officially sold out

Tickets to Swift's four Sydney stadium shows sold out in two hours on June 30, while her Melbourne shows sold out in the same amount of time after they went on sale at 2pm.

Frontier Touring said at 4.05pm that all general admission for Melbourne's Friday, Saturday and Sunday shows had "been exhausted", but some VIP and hotel packages were still available.

Earlier at about 11.50am Frontier Touring confirmed Sydney's general tickets had all been allocated with only the pricier VIP and hotel packages left available.

Those who miss out are being warned not to turn to unauthorised resellers with official resales to be offered through Ticketek from September 4.

Reactions on social media ranged from jubilation as fans got their hands on a treasured ticket while others' nightmares were realised.

Many fans slammed the ticketing process which saw some people let in to the site multiple times while others never got past the 'waiting lounge'.

"This randomised system is honestly the most unhelpful thing ever," one person tweeted.

Another said they "waited hours and didn't get let in once so why did some people get let in multiple times to buy multiple tickets to multiple shows !!!"

It was revealed during the week that no advantage was given to fans who jumped onto the Ticketek website early, with the process randomised rather than acting like a queue.

It comes as millions of Aussies have spent hours staring at the 'lounge' screen this week trying to snap up a seat at The Eras Tour.

Two pre-sales sold-out during the week including on June 28 when a record-breaking 800,000 people waited in the Ticketek 'lounge' for tickets to the Sydney shows.

More than four million people in total tried to secure tickets to the Australian tour in pre-sales.

And many fans are still expected to miss out during the June 30 sale despite two more tour dates being added due to "unprecedented demand".

Fans are advised to jump on at least 15 minutes before the sale starts and not to refresh the page once they're in the 'lounge'.

The 12-time Grammy winner is bringing her global tour down under in what will be Swift's first visit since 2018.

In that time the pop star has released four new albums including her latest Midnights and re-records of old fan favourites Fearless and Red.

With legions of fans across Australia her shows in Melbourne and Sydney are attracting huge demand.

The extra shows announced on June 29 means Swift will be the first artist since Madonna in 1993 to play three concerts at the MCG and the first ever to perform four shows at Sydney's Accord Stadium.

Frontier Touring has confirmed no further dates will be added making Friday's sale the last chance for fans to get their hands on a ticket.
