Thousands of people have joined the call for Australia's highest civilian bravery award to be bestowed on the two Australians who played a crucial role in the rescue of a Thai youth soccer team from a submerged cave.
A change.org petition calls for Adelaide anaesthetist Richard "Harry" Harris and his longtime dive partner, retired Perth vet Craig Challen, to be awarded the Cross of Valour.
"Essentially a civilian version of the military Victoria Cross, the CV has only been awarded five times since inception, in 1975," petition organiser Matthew Irvine said.
"I respectfully request that (Julie) Bishop, in her capacity as foreign minister, nominate Dr Harris and Mr Challen for this highest of honours."
By Friday the petition had attracted 33,307 signatures.
Dr Harris was considered essential to the rescue efforts in Thailand because of his unique skills as a medical retrieval expert and his 30 years cave-diving experience.
His efforts to help bring the 12 boys and their coach to safety was marked by personal tragedy, with his father passing away just hours after the mission was successfully completed.
Along with his dive buddy, Dr Harris said the operation was "almost beyond our imagination".
"We are humbled to have been able to provide our expertise and experience to assist in this international operation led by the Thai government," they said in a statement.
Calls for bravery awards for the pair have also drawn support from Opposition Leader Bill Shorten who congratulated all those involved in the "miracle" rescue.
"I've seen rescues in the past but this one seemed so complex and so difficult and so harrowing," he told reporters in Adelaide.
"I think it is a miracle."
