Shane Warne has retired from all forms of cricket after announcing he will not play at this year's Big Bash tournament with the Melbourne Stars.

The 43-year-old Australian is the second-highest Test wicket-taker of all time with 708 in 145 Tests, as well as 293 more in 194 one-day internationals.

Warne, who retired from Test cricket in 2007, featured in each of the last two seasons of the Twenty20 Big Bash event.

"I think the time is right for me to hang up my Big Bash boots," he said.

"Juggling business, family and commentary commitments across two continents is not easy.

"I've always loved the game but now it's time to observe."

Warne bowed out of Test cricket after helping Australia to a 5-0 Ashes whitewash of England in 2007.

The Australian retired from the first-class game in 2008 after a spell captaining English county side Hampshire.

Warne quit all forms of cricket in May 2011 when he left Rajasthan Royals in the Indian Premier League but announced in November of the same year that he would feature in the Big Bash tournament.
