Things are heating up in Sydney with just an hour to go until Ireland’s historic World Cup opener against Australia.

Over 82,000 fans will pack into the sold-out Stadium Australia in Sydney for the Ireland women’s team’s first ever match in a competitive tournament.

Thousands of fans have travelled over from Ireland – to join up with the green army that is already living Down Under.

These Irish supporters in Sydney are feeling confident.

“I’m going to all three games and to the quarter-finals and semi-finals – we’re going to win them all,” said one man.

“Katie McCabe, what a legend.

“Just qualifying and getting here was amazing,” said one woman. “Back the girls, back the girls.”

“So, it means a lot, especially how far the girls have come,” she said.

“We are really, really excited and can’t wait to support them today in the stadium – especially with how well they have done so far.

“All the nation is behind the girls.”

“It may be Australia in their home ground but we are f***ing Ireland man.

“We are going to do it. 2-0 to the girls – come on.”
