While the 34-year-old's Greater Western Sydney Giants’ lost their Super Netball major semi-final to the West Coast Fever by just six points, a win against the Sunshine Coast Lightning in Sunday's preliminary final will at the very least give her a grand final farewell from the game.

As is the way with many modern sports stars, Pettitt is pulling the pin on a distinguished career while still at her peak.

“I feel like I’m playing well still, which is why I wanted to retire. I didn't want to play one season too many,” the Quaama native said.

"It's been 17 years, so it's time to see what else life can offer.”

Her move away from the sport will give her time to focus on running her Albion Park cafe, and guiding the next generation of elite netballers to the top stage through her coaching business.

She walks away from the game with a world championship, three Commonwealth Games medals and three world series medals, in a stellar 71 games during her 12 year national career.

"I think playing in the 2006 Commonwealth Games in Melbourne was a dream come true, and any chance to be in green and gold has been a highlight,” she said.

Pettitt has come a long way since her a flawless performance of 26 points from 26 shots to claim a grand final win in her first season with the Sydney Swifts in 2006.

Her strong work ethic saw her push through moments in her career, including twice fighting her way back into the national squad.

"I'm a very competitive person, so if someone says I can’t do something I prove them wrong," she said.

Pettitt said there will be a “big celebration” if the Giants can take out this year’s premiership, which with her 200-plus game record and vast finals experience, is highly possible.
