Following the outbreak of World War II in the Pacific, he was sent to Australia as a captain with the Chinese military mission.
[2] The permit was issued by the Immigration Minister Arthur Calwell, who became a close friend of the Wang family, despite his lifelong support for White Australia.
The Australian Dictionary of Biography notes: In 1965 Wang, on the nomination of Calwell (whose electorate covered the City of Melbourne), was appointed one of the first two Chinese-Australian Justices of the Peace in Australia.
As a Councillor he led the push for the extension of shopping hours and the establishment of new parks in the city, and worked on the approval of Melbourne's Chinatown Project.
It was widely expected that he would be elected as Lord Mayor of Melbourne, but his early death from a heart attack prevented this.
