Mr McWilliam was posthumously named a Member in the General Division of the Order of Australia by Governor-General Sir Peter Cosgrove on Tuesday.

Mr McWilliam’s wife Margaret said he would have been “thrilled” about receiving the award.

“I don’t think he would have made a big deal about it though,” Mrs McWilliam said.

Mr McWilliam was recognised for his services to the community, including being a benefactor of St Vincent’s Private Community Hospital, helping set up Pioneer Lodge and other numerous contributions.

“He made a lot of money and he gave a lot away,” Mrs McWilliam said.

At Mr McWilliam’s funeral in November, mayor John Dal Broi announced he would be named a freeman of the city after a unanimous vote, the highest honour the city could bestow upon him.

The friendly community spirit was appointed to the Order of Australia alongside 174 other distinguished individuals.

“Today’s recipients now join the company of more than 40,000 women and men whose actions have enriched our community and whose values we hold dear,” the Governor-General said.

“On behalf of all Australians, I thank them for their contributions. They are a source of courage, support and inspiration, and we are a stronger, safer and more caring nation because of them.”

The Order of Australia was the pre-eminent means of recognising Australians who had demonstrated outstanding service or exceptional achievement. Anyone could nominate any Australian within the general division, and all nominations were considered by the Council for the Order of Australia, which recommended awards for the Governor-General’s approval. The 2016 Honours List recognised a diverse range of contributions and service across all fields, including professional endeavours, community service, defence and emergency services personnel.
