Bronte (left) and Cate Campbell are the swimming sisters targeting the top step of the podium at April's Commonwealth Games.

Just two years apart, the siblings boast a tight bond despite being freestyle rivals in the pool.

They both recall discussing their dreams for world domination in the back of the family car on their way to swimming practice when they were growing up.

Between them, Bronte (far left) and Cate (central) have taken the swimming world by storm at Olympic, world and Commonwealth level.

But at the Rio Olympics, things went awry with Cate's form eluding her in the 100 meter freestyle final and Bronte struggling with injury in the build-up.

For Cate (left), her experience at Rio left her "heartbroken."

Despite that, the sisters still came away with Olympic gold in the 4x100m freestyle relay.

And having taken time away from the pool, they are very much back to winning ways on the eve of their home Games.
