American Taylor Swift fans were left reeling after a video from one of her Australian concerts went viral.

The global megastar, 34, has been impressing Swifties in Melbourne and Sydney with a string of epic concerts, with the tour Down Under set to come to a close on Monday night.

The much-awaited shows have seen upwards of 80,000 fans descending on the sold-out stadiums as Swiftie mania has taken the country by storm.

And a time-lapse video showing the masses from Sydney’s Accor Stadium crowding on to trains at Olympic Park station after the concerts has stunned international fans.

Crowds – which also included blink-182 fans from a gig at the neighbouring Qudos Bank Arena – were seen pouring into the station before being quickly swept onto trains.

The shows have seen upwards of 80,000 fans descending on the sold-out stadiums as Swiftie mania has hit the country, and pictures of the post-concert public transport have gone viral

Crowds – which also included blink-182 fans from a gig at the neighbouring Qudos Bank Arena – were seen pouring into the station before being ferried on to trains

The trains were seen leaving every few minutes, with the huge number of concertgoers seamlessly being ferried on to them to get them home.

And the footage left some American fans with a sense of envy as they told how post-concert travel isn’t always as smooth back stateside and admitted their ‘jealousy’.

One wrote: ‘Was absolutely amazed by how well this was handled at Olympic Park and the MCG last week. Can only be jealous as an American. Transit rocks!’

Another said: ‘Hi North American here! Most stadiums have ZERO access to public transportation and are not walkable. You are fortunate. Hope this helps!’

A third penned: ‘I sometimes travel an hour to a concert or sporting event because I live in a very rural area. Driving is the only option.’

Another Australian commented on how many American fans had been wondering why there was little parking around the venue, using the video to show how it arguably isn’t needed.

The video was shared to Twitter by account Every Sydney Station alongside the caption: ‘The Tay Tay Express from Olympic Park ran smoothly last night.’

‘I think people were around later than they budgeted for, still big crowds as it got close to last train just before 1am. Here’s trains to Central, the westbound platform was just as busy. Spot the Blink 182 fans.’

Of the process, they added: ‘People queue outside and are let onto the platform when there’s space. Staff at every door keep people safe.

‘Each train arrives empty and takes nearly 2,000 people, every few minutes split between two tracks. Impressive, but shows how Sydney really needs 24hr trains for weekends.’

Swifties worldwide have also been jealous of Taylor treating Aussie fans to mash-ups of her smash hit songs during her two-track surprise segment.

At all three of her Sydney shows over the weekend, Anti-Hero singer played a mash-up of multiple different tracks for her ‘surprise songs’ portion of the show.

At Sunday’s show, the first mash-up was of her beloved vault track, Is It Over Now from 1989 (Taylor’s Version), and I Wish You Would, also from 1989, which she played on her acoustic guitar.

During the second mash-up she performed Haunted, first released on her third album Speak Now, and Exile, off her Folklore album.

A fan shared a video of the mash-ups on TikTok and Swifties went wild in the comments.

‘These mash-ups are making me emotional first thing this am,’ one fan wrote, adding the crying emoji.
