Shane Warne

Victorian Premier Daniel Andrews said 42,300 people have already snapped up a free ticket for the event at the Melbourne Cricket Ground next Wednesday.

It will be the wider public's first chance to say goodbye to Warne after his shock, sudden death from a suspected heart attack while staying at the Thai resort island of Koh Samui on March 4.

Patrons will need to be fully vaccinated to attend the service, which is expected to run for two hours.

Rather than flowers, Warne's family has asked people to donate to The Florey Institute of Neuroscience and Mental Health.

Warne, one of the finest bowlers of all time whose talent and personality transcended cricket, died about two weeks ago at the age of 52 while on holiday on the Thai resort island of Koh Samui. Thai authorities said an autopsy showed his death was from natural causes and Warne's family later accepted the findings.

About 80 people attended the service including retired Australian Test captains Mark Taylor, Allan Border and Michael Clarke, while former England skipper Michael Vaughan was also present.

A senior Thai police official said the post mortem exam showed no signs of foul play in the 52-year-old's death.

Warne, who is considered to be one of the greatest cricketers of all time, died of a suspected heart attack on Koh Samui island, where he was holidaying.

The Australian government is bringing his body back to Australia where he will be given a state funeral.

Warne was a larger-than-life figure whose fame transcended sport and he inspired generations of fans.

Warne, 52, was holidaying with friends in Thailand when he was found unresponsive in his villa on Friday and could not be revived.

Victorian Premier Daniel Andrews said on Twitter that he had spoken with Warne's family on Sunday and that they agreed to the service.

Andrews said the state funeral would be an opportunity for Victorians to pay tribute to Warne's contribution to cricket, the state and the country.

He said details would be finalised in the coming days.

Test cricket's second-most successful bowler, the former leg-spinner has confirmed his "baggy green" cap has been sold through auction for $1,007,500.

Twenty-seven people have been killed so far and thousands made homeless as the huge fires have scorched through more than 10.3 million hectares (25.5 million acres) of land, an area the size of South Korea.

Several towns and communities in the heavily populated southeastern region of the country have been advised once again to be alert and evacuate if needed.
