LISMORE-BORN Commonwealth Games gold medallist Naazmi Johnston has gone mainstream, appearing on popular entertainment show Australia's Got Talent on Channel Seven.

Johnston's Meriden Rhythmix team was given a standing ovation and got the tick of approval from judges Brian McFadden and Dannii Minogue in a pre-recorded performance that aired on Wednesday night.

“The producers told one of our coaches about the show, so we decided to enter a team,” Johnston said.

“It's turned out to be a great avenue to lift the profile of the sport.”

The recently retired rhythmic gymnast went out with a bang, winning three gold and two silver medals in Delhi last October.

“I competed at the Olympics (2008) and achieved everything I wanted to do,” she said.

“I got five medals in Delhi and it (retiring) seemed like the right thing to do.”

The 21-year-old now spends her time as a coach in Sydney.

She is busy in planning and preparation for the team's next performance on Australia's Got Talent.

“It's great to get the chance to perform without the pressure of normal competition,” Johnston said.

“We focus less on technique and try to serve up something unique that the public hasn't seen before.

“Its pretty full-on, when you're backstage and you see the look on some of the faces when they come back from their performance.

“We didn't even know that the judges used a buzzer when they have seen enough of the performance.

“They used it on the group before us, and we had no back-up plan to stop or anything like that during our routine.

“That was a bit scary, we were lucky they let us do the whole routine.”

The winner of the competition receives $250,000.

You can follow Johnston's progress on Tuesday and Wednesday nights at 7.30pm.
