Two-time Olympic swimmer and television presenter Elka Whalan and husband, Thomas, an Olympic water polo player, know more about being in the water than most.
But that does not mean they are relaxed about water safety and their young children Nevada, 3, and Edison, 2. Especially after a recent swimming scare.
Ms Whalan, who is expecting her third child next month, had to jump into a family pool to rescue Nevada.

''She had her tutu dress on and pants, and I had heavy jeans on and high heels,'' she said. The Sydney and Athens Olympian said she looked the other way for one second and Nevada fell in.
''I had to jump in straight away and get her. I didn't even hesitate twice being pregnant or in my jeans and my new velvet shoes. I pulled her out of the water and my husband was there and we got her to calm down, to take her breath and she vomited up some water,'' Ms Whalan said.
''For the first time we realised how quickly it can happen.''
Her philosophy is, if you have two children you need two pairs of eyes.
Speaking in support of The Sun-Herald's SwimWise safety awareness campaign, Ms Whalan said it was a tragedy to hear of toddlers drowning, especially when they were of similar age to her own children.
She said young children often did not realise when they were tired.
''When they are [tired] … some children will be vocal and call help and others are the silent ones and they just go under the water. Our son would do that. You actually have to ask him: 'Do you want help, are you a bit tired?''' Ms Whalan said.
''You just can't afford to leave your children. No matter who it is … if they say: 'we'll look after the kids' and there are five kids and two adults, I would still just say, 'no'.''
