Malcolm Turnbull has received some pointers from Adelaide karate kids on his fight stance technique.
The prime minister took his election campaign to Paradise on Saturday morning to rally support for Innovation Minister Christopher Pyne in his seat of Sturt.
Mr Pyne is warding off a political challenge from the Nick Xenophon Team.
Mr Turnbull announced a $5 million federal contribution towards a project to redevelop the Campbelltown Oval.
The local council will match the cash.
The revamp will allow the local karate club to expand its student numbers and move out of the old scout building it has outgrown.
There are no change rooms or toilets in the building.
Assistant instructor Travis Baverstock told AAP the sport was more than just about fighting.
It provided youngsters with life skills, increased confidence, stranger danger awareness and self-discipline, he said.
His daughter Danika, 8, loves doing karate and learning new moves.
She posed for a photo with Mr Turnbull, and some of her classmates, showing off their fight stance.
"I thought (his stance) was pretty good but he should have kept his guard up," she told AAP demonstrating the proper technique.
Mr Turnbull said community sport was the best remedy against childhood obesity and promoted healthy living.
The Campbelltown City Band was in attendance at the announcement but declined to play their brass instruments because band members forgot to bring sheets of music.
Mr Turnbull will address the party faithful in Adelaide on Saturday before flying to Sydney.
