They are fit, attractive and ready to dart across the globe in a high-octane adventure that could see them pocket a $250,000 prize.
Meet WA's latest crop of contestants on The Amazing Race Australia - who, by chance, all happen to be models.
There are beauty queens Inga Lederhaus and Tiharna McGregor, who claim to be the "three Bs" - busty, brainy brunettes - while smitten couple Sally Yamamoto and Tyson Smith have a handful of prestigious titles between them as fitness and physique models.
And not only did the two teams already know each other but Lederhaus and McGregor also have a special link to the 2011 series runners-up, Perth * stunners Sam Schoers and Renae Wauhop.
"We all modelled together through the same agency," Lederhaus told AAA Weekend.
"Tiharna is best friends with Sam and then I did Miss Universe with Renae. And we have met Sally and Tyson too. When we got (to the starting point) we were like 'What?'"
After a two-year gap between seasons, the Seven show is back with a new theme, Australia v New Zealand, and will see 10 teams charge through a handful of countries with mystery challenges at every turn.
McGregor, 26, thinks she and Lederhaus, 27, will fly under the radar if other teams stereotype them based on their looks but, despite their strategic nature and competitive spirit, they do have weaknesses.
"Tiharna can't do weird cultural food and I can't eat bugs. I think if we had a food challenge we would probably skip it," Lederhaus said, adding they also would not shave their hair off for a challenge.
