Shane Warne's state memorial to be held at MCG on March 30

Shane Warne will be publicly farewelled at the Melbourne Cricket Ground, home to many of his greatest sports moments, later this month.

Victorian premier Daniel Andrews has confirmed the MCG as the venue for a state memorial service on March 30 to honour the Australian legend, who died suddenly due to heart attack in Thailand last week.

"There's nowhere in the world more appropriate to farewell Warnie than the 'G," Andrews tweeted on Wednesday.

The MCG was the stage of the legspinner's famous Ashes hat-trick in 1994 and the 700th Test wicket on Boxing Day in 2006, his final series before he retired from international cricket.

Ticket information for the evening event is yet to be released, but the premier said there will be no crowd cap at the venue, which can hold up to 100,000 spectators.

"It'll be a very big event. It will be a celebration of his life as it should be," Andrews said.

Autopsy results showed that Warne died from a suspected heart attack, confirming the death was due to natural causes with no signs of foul play.

Deputy director of Samui Hospital Songyot Chayaninporamet said the autopsy showed Warne, 52, died of a "congenital disease".

Following his death on the Thai resort island of Koh Samui, Warne's body was taken by ferry to the mainland city of Surat Thani on Sunday. It was transported to Bangkok on Monday night and was being prepared to fly home to Melbourne, according to media reports.

Warne's family issued a statement on Monday describing the night of his death on March 4 as the beginning of "a never-ending nightmare".
