Matildas midfielders Tameka Butt and Elise Kellond-Knight have known each other since they were young and could be headed to France next month.
The two met while playing representative football on Queensland's Gold Coast before going through the Queensland Academy of Sport system together.
"I do have memories of Debbie (Tameka's mum), plaiting her hair before every game when we were about 12-year-old," Kellond Knight told Optus Sport.
From there, they've pretty much had every step of their career together from being foundation members of Brisbane Roar to making their Matildas debut in the same year.
Meaning it's rare for them not to be roommates.
Although after the Matildas got a new coach in Ante Milicic earlier this year, Kellond-Knight and Yallop were unsure if they would continue to be roommates.
"We obviously got a new coach in and the first thing we thought is 'oh are we going to be roomies still?'," Yallop said.
"We've been roomies for at least 10 years."
The duo also played in Scandinavia last season, Yallop with Norwegian club Klepp IL and Kellond-Knight with Hammarby in Sweden.
When Kellond-Knight came to Kleppe last year to visit, the pair, who are keen surfers, wanted to catch some waves after missing the ones they get while in Australia and decided to suit up.
"...we got pretty desperate in Norway and went for a surf there in some ripple waves you'd call it with the full body suit on, the headgear, the gloves and the booties," Yallop said.
"So I think we're water babies for sure."
Heading into France, expectations are high for the Matildas, who made the quarter-finals in Canada last time and Kellond-Knight shares those sentiments.
"We went Round of 16, quarter-finals so, in theory, we should at least make a semi-final this coming World Cup so that would be my expectation and once you put the team in that position then anything can happen," she said.
And hopefully, they won't lose any bags.
