Australian cricketing legend Shane Warne is being mourned by fans and friends at home and around the world following his sudden death in Thailand.

Flowers, meat pies and beer cans have been laid at Shane Warne's statue at the MCG following the Australian cricketing legend's sudden death.

The 52-year-old died of a suspected heart attack while on holiday in Koh Samui, Thailand, on Friday.

Warne, who was born in the Melbourne suburb of Upper Ferntree Gully, leaves behind daughters Brooke, 24, and Summer, 20, and son Jackson, 22.

His family has been offered a state funeral by the Victorian and commonwealth governments, such was his renown which went beyond the cricket pitch he used to mystify opponents.

Victorian Premier Daniel Andrews said the MCG's Great Southern Stand would be renamed the S.K. Warne Stand in a "permanent tribute to an amazing Victorian".

"Nobody who saw Shane Warne play will ever forget him," Mr Andrews said. "To us, he was the greatest - but to his family, he was so much more.

"Our hearts are breaking for Shane's family and friends."

Australian officials are scheduled to arrive in Thailand on Saturday to assist Thai authorities and help arrange the repatriation process.

Prime Minister Scott Morrison offered his condolences to the Warne family in a written statement.

"Shane was his own man, following his own path," Mr Morrison said.

"In those times when he could have been knocked down by the headlines, he got back up. He always did.

"We have lost one of Australia's greatest cricketers and today we are bewildered by this sad and sudden loss."

Like many geniuses of their crafts, the leg spinner had an outlandish personality that matched his sporting brilliance. He dated models and movie stars. He drank and smoked.

In the press, he was sometimes a villain but he was always forgiven. Australia's sports-loving public just wanted to see him bowl.

Hollywood star Russell Crowe tweeted he was having a hard time accepting the news.

"Genius player. Grand company. Loyal friend," he tweeted.

Rolling Stones frontman and passionate cricket fan Mick Jagger tweeted: "He brought such joy to the game and was the greatest spin bowler ever."

Warne was taken to the Thai International Hospital after his suspected heart-attack on Friday. Reuters news agency is reporting one of Warne's friends performed CPR on him after finding the 52-year-old unresponsive in a villa.

British Prime Minister Boris Johnson described Warne as "one of the nicest guys you could meet", noting his work with disadvantaged children.

Australian actor Magda Szubanski, who worked with Warne on the sitcom Kath & Kim, said she was in utter shock.

"Inconceivable that a life crammed with so much genius and larrikin charm could be snuffed out so suddenly and so soon," she posted on Instagram.
