Nine Australian heroes involved in the Thai cave rescue will be honoured for their bravery at a ceremony on Tuesday.
Governor-General Sir Peter Cosgrove will present medals to those involved in the mission, including Dr Richard 'Harry' Harris, Craig Challen and Chief Petty Officer Troy Eather.
Prime Minister Malcolm Turnbull and Opposition Leader Bill Shorten will be among those attending the reception at Government House.
"I want to say to the Aussies involved in the rescue: You did Australia proud, well done," Mr Shorten told reporters in Tasmania before heading to Canberra.
Mr Turnbull has previously described the mission to rescue 12 boys and their 25-year-old soccer coach as an extraordinary act of heroism, professionalism, discipline and teamwork.

It will be the first time the rescuers have been reunited since returning to Australia on July 13.
Adelaide anaesthetist Dr Harris and his dive partner, retired Perth vet Mr Challen, were among an international team of cave-diving experts who freed the trapped boys and their coach.
Sydney-based Chief Petty Officer Eather was a key figure in Operation Thailand Assist, having been involved in a number of significant missions since joining the Navy in 1991.
Thailand's ambassador to Australia and Australia's ambassador to Thailand, along with the acting chief of the Defence Force and acting Australian Federal Police commissioner, will be attending on Tuesday.
So too will various senior government representatives.
The names of the AFP medal recipients are being withheld until the ceremony.
