Meet James and Luka: two boys not afraid to try something new.
LUKA: I'm 9 years old, and I'm the first boy in Australia to do synchro.
LUKA: I like all the moves and how it's really creative, because yeah I'm a creative person.
Synchronised swimming is a sport that's been around for over a century and actually used to be called 'water ballet'!
JAMES, SYNCHRONISED SWIMMER: I get to keep fit, and I made a lot of friends with the girls.
James' sister Zoe had been practicing with the Gold Coast Mermaids - a synchronised swimming squad in Queensland. And he'd always liked gymnastics and swimming.
JAMES, SYNCHRONISED SWIMMER: I saw Zoe doing it in the pool and I thought I might have a go.
Having James and Luka on the squad means the Mermaids now have their own mer-men!
JAMES: It's kind of weird not having any other boys around except one, but I do get along with all the girls and it's really fun
And each week, they train alongside their female team mates.
LUCA, SYNCHRONISED SWIMMER: They just treat me like another person doing synchro. Like everyone else.
There are big synchronised swimming competitions around the world and you might have even seen it in the Olympics! But at the moment it's one of two Olympic sports that only allows women to compete.
Just a couple of years ago, mixed pairs were allowed to enter the World Championships of synchronised swimming for the first time. But these guys would like to make a splash at the Olympics, so they're campaigning for the rules to change there too.
Their coach says having boys and girls performing together could be good for the sport because it could inspire new types of routines.
James and Luka are hoping that by the 2024 Olympic games they'll be allowed to compete. Until then they're going to keep practising their tumbles, turns, kicks, and of course their timing.
JAMES: Yeah I'd do a duet with my sister. She'd probably kick my butt.
