England have been sabotaged as they look to make the final of the Women's World Cup.
On Wednesday, the Lionesses will lock horns with Australia hoping to make the final of a major tournament for the second time in succession - having gone all the way at the European Championships last summer.
However, Australia fans have been buying tickets in the England end to boost their chances of making the showpiece event.
A post on the Football Association's website shared an access code by the name of 'Lioness' intended exclusively for England fans.
Australia fans are out to sabotage England ahead of Women's World Cup clash
But Aussie supporters have managed to buy tickets in that section of the stadium and plan on cheering their side on.
England had been given an allocation of 1,970 tickets following their 2-1 victory over Colombia on Saturday.
And Aussies have been boating they'll be wearing their famous yellow jerseys, despite the chaos that could cause.
A Facebook post on the Matildas and A-League Women Supporters Group page contained many messages from jubilant fans.
One user stated: "The code was just meant to be for England supporters. Matildas fans were spreading the code last night and now they are all sold out for actual England supporters."
And a second said: "Scored these English supporter tickets too last night. Proudly going to be wearing our Matildas gear."
The report says that, before the incident, as many as 8,000 England fans had been expected to watch on from the stands.
But that number now stands to be less following the Aussies' hijack.
Meanwhile, England star Keira Walsh has insisted the pressure is all on Australia ahead of the blockbuster showdown.
She said: "The pressure is on Australia, that is a different thing to cope with.
"But they are a great team, whether they feel the pressure or not.
"The way they play they don't look like they feel it. They are very physical and we have to be ready for that. "It's just about going in confident and playing on the front foot."
Australia previously beat England back in April, winning 2-0 courtesy of goals from Sam Kerr and Charlotte Grant.
Walsh thinks that result won't have any bearing on Wednesday's fixture, however.
She stated: "It's a difficult game but we weren't at our best then and I'm sure they are aware of that.
"The momentum at a World Cup is different.
"It's amazing to see for women's football the amount of support Australia are getting. There is pressure on both teams, we felt it at a home Euros in the summer."
England have now made the last four of the Women's World Cup for the third time in a row.
