The FA is set to review its ticket sales process after Australia fans reportedly bought up seats intended to be available exclusively to England supporters.
An official England supporters’ allocation of 1,970 tickets was released for Wednesday’s semi-final after the Lionesses beat Colombia 2-1 on Saturday.
A post on the FA-run England Football website said supporters could buy their tickets via Fifa using the access code “Lioness”.
But the code was soon picked up and shared by an Australia-supporting Facebook group, the Daily Mail reported, allowing fans of the home team to snap up some of the visitors’ seats.
A spokesperson for the FA told i: “We worked with Fifa to secure an additional allocation of tickets for England’s World Cup Semi-Final against Australia.
“The details of how to purchase these tickets were communicated directly to our fans on our England Football channel, and we are disappointed to see reports that a limited number of these tickets have been accessed by other fans.
“We are working with Fifa to review this ticketing process going forward.”
Australia fans were already expected to outnumber the visitors by around 10 to one at the 83,500-seater Accor Stadium in Sydney.
Fans back home could get the chance to watch the Lionesses secure World Cup victory alongside thousands of others should England book their place in the final.
Sadiq Khan’s office has said that City Hall will “work with partners to look at the best way to enable Londoners to come together to support the team” if England make it to Sunday’s match.
Last year’s Euros victory was screened in Trafalgar Square to 7,000 supporters who attended for free on a first-come-first-served basis.
A spokesperson for the Mayor of London said: “We encourage Londoners to come together this Wednesday to cheer the team onto glory and support pubs, bars and restaurants across the capital.
“Should they reach the final, City Hall will work with partners to look at the best way to enable Londoners to come together to support the team on what is sure to be a momentous occasion.”
