Thousands of people including all seven living prime ministers have converged on Sydney's Town Hall to celebrate the life of the late Gough Whitlam
The 21st Prime Minister of Australia died last month aged 98. He is widely considered as one of Australia's most transformative prime ministers.
The Town Hall was packed with supporters who vocally applauded Labor politicians who entered.
And there were loud boos for Liberal Prime Minister John Howard as he entered the hall.
UPDATE 1140 AEST: ABC Four Corners host and former Whitlam staffer Kerry O'Brien opened the memorial with a joke about choosing the Town Hall: "His first choice was to have a funeral pyre in the Senate… to take Upper House with him."
UPDATE 1105 AEST: Former Prime Minister Hawke approached Prime Minister Abbott for a quick chat.
Current Labor MPs arrived to meet and greet the gathered crowd outside the Town Hall.
Jimmy Wavehill from Wavehill Station embraced NT Labor Senator Warren Snowden. Mr Wavehill is one of several Gurindji elders to have travelled from remote Kalkaringi in the Northern Territory to pay his respects.
Mr Wavehill was there at Wavehill Station in 1975 when Mr Whitlam handed back control of the Aboriginal land to Vincent Lingiari and his family. It's widely considered one of the turning points of the Land Right Movement in Australia.
ABC journalist Kerry O'Brien, Cate Blanchett, Noel Pearson and Mr Whitlam's son Anthony Whitlam will all speak at the service.
Organisational issues have plagued the morning. There are several reports of public attendees not being allowed into the Town Hall, despite registering weeks ago.
