"I've definitely finished up playing, that's for sure," White told cricket.com.au late Friday.
"I had a one-year playing contract with the Strikers. I only played a handful of games with them last year and in those games I would have needed to play really well to get another deal.
"To be totally honest, I'm pretty content. I think my time is definitely up. I've had enough from a playing point of view and I'm ready to focus on coaching."
A destructive batsman and competent legspinner, White was primarily a limited-overs specialist, captaining Australia seven times in one-day and T20 matches.
His four Tests were all in India on a 2008 tour, but he took only five wickets and was discarded.
