More than 60,000 people are expected at the MCG for Shane Warne's state memorial service on Wednesday night, with more tickets made available on Tuesday.
With 50,000 already taken, another 10,000-15,000 new seats have opened up for people to pay tribute to the cricketing great, who died earlier this month after suffering a heart attack while on holiday in Thailand, aged 52.
Television personality Eddie McGuire, whose production company has organised the event, said that as well as family and close friends honouring Warne there would be a mix of performances by celebrities in Australia and abroad.
Proving how Warne's popularity stretched beyond cricket, a number of international stars will perform remotely, either live or taped.
"Elton John, Chris Martin, Robbie Williams, and Ed Sheeran will be singing dedicated songs to Shane Warne in his memory and for this particular night," McGuire said.
Jon Stevens is set to front a band playing a medley of Warne's favourite INXS and Noiseworks songs while Anthony Callea will also sing.
Others including Russell Crowe, Hugh Jackman, Kylie and Dannii Minogue, James Packer, Eric Bana, Greg Norman, and Kelly Slater will also pay tribute to Warne.
Cricket greats Nasser Hussain, Wasim Akram and Brian Lara are flying into Melbourne for the memorial, held at the venue where the spin king captured his 700th Test wicket against Ashes foe England.
Warne's three children, his father Keith and brother Jason will also speak, while the Shane Warne Stand, formerly known as the Great Southern Stand, will be unveiled.
McGuire said the two-hour event would be "quite spectacular".
"We started with a blank sheet of paper and it filled so quickly because the world wanted to come and pay tribute to Shane Warne," McGuire said.
"He was a local boy who made good and gave to everybody everything that he had.
"It's going to be a wonderful show, it's going to be fitting for what we're trying to achieve.
"We'd like to invite people to come because this is going to be just one of the greatest events in the history of the city, in this country, in many ways - a tribute to a champion."
