Few would have predicted pole dancing would be on the horizon for a child-like 13-year-old Melissa Wu when she first burst onto the world diving scene.

But the Olympic silver medallist has used the sometimes misunderstood pursuit to help launch a diving comeback at this weekend's Queensland championships in Brisbane.

A pint-sized Wu looked every bit her tender 13 years when she came of age with a surprise national 10m platform title in 2006, finishing ahead of Olympic medallists Chantelle Newbery and Loudy Tourky to force her way into the Commonwealth Games team.

But by 2013 the 21-year-old was more than feeling her age thanks to a niggling back injury, forcing her to take a break and withdraw from May's world championship selection trials.

Wu, though, is confident of returning to her best again thanks to a left-field recovery approach.

"Pole dancing has helped me with a couple of things," Wu said.

"It hasn't had a negative impact on my training.

"A lot of the exercises my physio has been giving me involve trying to counter that forward movement, stretching back and that sort of thing.

"I do a lot of that in pole, so it's actually been really good for stretching my back out the other way."

Fresh from her first true break from the sport in nine years, Wu is now hopeful of adding to her three medal Commonwealth Games haul - including 2010 Delhi 10m synchronised gold - at Glasgow next year.

"It gave me a bit of a mental break too, because I'd been competing non-stop every year since I was 13," said Wu who admits she still has to manage her back pain.

"So it was nice to have one year to rest my body and rest my mind, as well.

"Since coming back I've really wanted it, and it's been good for my training to have that drive again to want to get back up there and compete.

"(Previously) I was scared to actually perform dives, because I knew the pain I was going to feel.

"I tried to push through it for so long, but I knew I had to rest it."

Wu aims to contest the 10m platform and synchro event with Adelaide's Rachel Bugg at Glasgow.

"I've definitely got my confidence back," she said.
