Taylor Swift fans are being told not to head to the pop star's shows in Sydney if they don't have a ticket.
Bosses at Accor Stadium say "only fans with a valid ticket should attend the precinct," when the pop princess performs on February 23, 24, 25 and 26.
However, fans who have not managed to get the sought-after tickets are planning to head to the venues.

When Swift played in the USA it became popular for fans not lucky enough to secure seats to gather outside the stadiums to listen to the show - extending the American tradition of "tailgating".
Tailgating or a tailgate party is an American tradition of hanging out in the car park with your car before concerts and sports games.
Revellers even take barbecues and booze.
However, American stadiums often have huge car parks with plenty of room.

There are almost a thousand fans in a Facebook group called Taylor Tailgate Sydney and more than 3000 in a "Taylor-Gate Melbourne" group.
"For the thousands of us who missed out on Eras tickets! Get your outfits, make your bracelets and let's Taylor-Gate at MCG!" the Melbourne group says.
The Sydney group says: "Thought we could start a "tailgate" style park party outside the stadium. They were doing it the USA and it was a vibe!"
However Accor bosses are urging fans not to bother.
"We want to ensure the best experience for all which is why only fans with a valid ticket should attend the precinct on show nights," a spokesman told 9News.com.au.
"Accor Stadium is enclosed which means the sound is maintained within the venue and there are no views of the stage from outside the stadium.

"To avoid disappointment, only fans with a ticket to the event are encouraged to attend on the night of their respective show."
As well as Swifts shows, on two nights Blink 182 are also playing at neighbouring Qudos Bank Arena in Sydney.
That means over 100,000 fans with tickets will already be heading to the precinct at Sydney Olympic Park, with train travel included in the cost of the seat.
9News has contacted the MCG where Swift is playing in Melbourne on February 16, 17 and 18 as well as tour company Frontier for comment
Number crunchers at economist Deloitte worked out for 9news.com.au that $220 million is set to be splashed in Australia by Swifties for the tour.
