Belinda Hedley knows all too well how quickly unsupervised children can lead to tragedy.
In March 2007, her sons, Braith and Seth, were only two years old when they were left alone for a minute or so.
That was enough time for her boys to sneak through a faulty gate and access the pool area.
Ms Hedley has shared her family's story to help Royal Life Saving Australia drive their message on pool safety.
"The most confronting thing that anyone will ever see is their dead children in front of them," Ms Hedley told SBS World News.
"That's what we saw, we saw both our boys laying face down in the pool."
Luckily Ms Hedley and her husband were able to perform CPR on the boys in time and save their lives.
Their quick thinking was the difference between life and death for the children.
"I think if you know CPR, and your child's there, you do it," Ms Hedley said.
"Anything helps, and we just didn't stop until we got them back."
Sharing her story as part of the RLSA 'Keep Watch' campaign, which aims to prevent future child drownings in Australia.
Since 2001, 432 children up to the age of four have drowned in Australia - the majority of these deaths are from New South Wales and Queensland.
More than half of the children drowned in home swimming pools.
The campaign aims to draw attention to how easy a small distraction can turn a normal situation into a tragedy.
"There's no room for complacency when it comes to children in and around the water," Royal Life Saving CEO Justin Scarr said.
"You have to constantly watch, stay within arms reach of children, and close the swimming pool gate really firmly when you're not using it."
Paramedics say CPR is a skill that's worth learning, especially for parents.
"If we have some CPR, even if it's not as effective, and people aren't sure they're doing it correctly, something is better than nothing," paramedic Rachel Steele said.
It's something Belinda Hedley knows to be true as it saved her family's life.
