The search for Australia's next generation of Paralympic stars is on.

After enjoying unprecedented levels of publicity as the Australian team finished fifth on the medal table - 32 gold medals, 23 silver, 30 bronze - at the recent London Paralympics, officials are already scouting new talent.

At a two-day return2sport expo at Sydney Olympic Park, several Paralympians were on hand to put 200 schoolchildren through their paces as representatives from more than 50 different sports supplied information.

While the expo was principally to get the children engaged in physical activity, the hunt was also underway for new Paralympic talent with children able to sign up for a talent search program.

After further testing, depending on the results, the Australian Paralympic Committee will recommend a list of sports the children are best suited to.

Six-time Paralympian and London sailing gold medallist Leisel Tesch said the expo was the perfect place for youngsters to engage with sport.

"All people with disabilities should have the opportunity to play sport," Tesch said.

"The journey is fantastic and the friendships and love you feel along the way makes it all worth it. I'm even crying with excitement because it's so good."

Kylie Gauchi, a London wheelchair basketball silver medallist, said having all the sports representatives in one place was hugely beneficial to parents and children.

"It's a real eye-opener, I don't think disabled kids realise how much sport there is that they can actually play," she said.
