The teenager will debut at the three-day national titles at the AIS in Canberra.

Chloe's pet event is the 200-metre obstacle.

"They put an obstacle in the pool at a quarter of the way and three-quarters of the way," she said.

"You have to dive in the water and go under the obstacle.

"It's pretty tight.

"(When practising) in Warrnambool I just pretend they're there."

Chloe, 16, qualified for the national championships after an impressive performance at the state titles in October at Shepparton, where she picked up three medals.

Her selection also came after solid training with the Victorian team, which involves travelling to Geelong or Melbourne every weekend.

"The training is based more on technique, so because we pick mannequins off the bottom of the pool, we work on the right way to pick them up."

Not only does Chloe clock up the kilometres for state training, she also clocks up hours of her own time.

"I'll do 10 hours in the pool and up to six hours in the ocean a week," the dedicated teenager said.

The Warrnambool Swimming Club member usually competes in under 17s but the age group doesn't exist at the national titles.

"There's under 16, under 19 and open," she said. "I'm too old for under 16."

Chloe will compete in a range of under 19 events on the first two days and in open events on the last day of competition ? a challenge she is looking forward to.

"They didn't have enough so they put me in there," she said.

"It will be pretty hard.

"I'm just going there to get points for Victoria.

"Of course Queensland and Western Australia will be up in front but we'll look to push them."

Chloe is the first Warrnambool swimmer to attend the Australian Pool Lifesaving Championships.

She has plans for Warrnambool to become the south-west's training base for pool lifesaving. The titles start on Thursday.
