Play School is turning 50 and gold medal winning Paralympian Kurt Fearnley is joining in on the party.

The Australian athlete, who famously crawled the Kokoda trail in 2009, is one of a number of special guest hosts appearing on the much-loved children’s program this week.

Sharing a sneak peek of his time on set to Twitter, Fearnley is seen singing as he leads a group of young children, including his own niece and nephew, on a “bear hunt”.

"I've got plenty on uncle brownie points up my sleeve," Fearnley tells SBS, adding he had as much of a ball filming as his niece and nephew did.

“I loved it. It was just a lot of fun something completely different, out of the sport realm, this one was just fun, a good chance to be a dad but to be a dad on tele."

Fearnley and his two-year-old son are now gearing up to watch the episode together when it airs on Friday.

"He takes everything as normal," Fearnley says, "he just points at the screen and says ‘dadda’, it’s pretty cute. We’ll put him down and I’ll sit down next to him and we’ll watch [the episode] in full."

Fearnley was approached to appear as a guest host six months ago and says he was all too happy to accept.

"Playschool is one of the most iconic shows in the country. 50 years of any TV program shows that it’s an ingrained part of growing up. I grew up on it, my young fella grows up on it, it was an honour to be asked," he says.

Dami Im, Lee Lin Chin and Hamish Blake are some of the other well-known personalities appearing as part of Play School’s 50th anniversary special.

Fearnley has three gold medals to his name after topping the field as a long and middle distance wheelchair racer at the 2004 and 2008 Paralympic Games.

He was born without the lower portion of his spine but has never let that hold him back, making him a strong disability advocate.
