Taylor Swift has finished her run of Sydney concerts. 

The American pop superstar completed the final of her four gigs at Accor stadium on Monday night.

She sent off the crowd with some very warm words, leaving the audience cheering in delight.

‘Looking at this crowd, the biggest crowd we’ve had at our four shows here!’ she told her fans.

The Eras Tour has seen more than 600,000 people attend the Australian leg.

A record-breaking 96,000 fans attending each of her three nights in Melbourne and a further 83,000 Swifties at each of her four shows in Sydney.

It comes after fans shared their anger after learning that scores of tickets were given away to the pop star’s Sydney concerts for free.

The tickets – many for prime seats – were given out at the Accor stadium venue minutes before, and even during the show, to hopeful fans waiting outside.

Some were given away by Taylor Nation, a fan group known for giving out free concert tickets to Swifties who missed out, but some are believed to have been given away by venue staff and even members of the pop’s star’s entourage.

Video circulating online shows members of Taylor Nation being surrounded by hopeful fans this weekend as they hand out free tickets.

Several told stories of being approached outside the venue and given tickets for good seats by mysterious men in black shirts.

Other fans discovered that tickets were available for purchase shortly before and even during the concert via the Ticketek’s original lounge link, despite being sold out on the main Ticketek website.
