Hundreds of mourners will pay tribute to former cabinet minister Peter Reith at a state memorial service in Melbourne.
The father of four and former defence minister died in early November aged 72 after a long battle with Alzheimer's disease.
Family, friends, former cabinet colleagues and politicians are expected to attend the service at St Andrew's church in Brighton on Thursday afternoon.
Members of the public are welcome to attend.
The event will be live streamed and mourners have been asked to donate to Dementia Australia rather than send flowers.
Mr Reith served as the member for Flinders, on Victoria's Mornington Peninsula, from 1982 to 1983 and from 1984 to 2001.
He was the Liberal party's deputy leader from 1990 to 1993 and served as a minister in the Howard government, having the portfolios of industrial relations, small business, employment and workplace relations and defence.
Opposition Leader Peter Dutton described Mr Reith was a "stalwart" of the Liberal Party and said he would be remembered for his "fearlessness" during the waterfront dispute and for his efforts on workplace reforms.
Mr Reith was involved in the Children Overboard issue in the lead up to the 2001 election, along with then Prime Minister John Howard and Immigration Minister Philip Ruddock.
The trio claimed on navy advice that children had been thrown off a leaky boat, apparently to force HMAS Adelaide to take them on board. That was later later shown to be incorrect.
After leaving politics in 2001 Mr Reith was a political commentator and served as a company director.
