Aside from the peer comment pointing out the bleedingly obvious, there's also a bit of history here:
In 1907 Justice Henry Bourne Higgins, President of the Commonwealth Conciliation and Arbitration Court, set the first federally arbitrated wages standard in Australia.
Using the Sunshine Harvester Factory as a test case, Justice Higgins took the pioneering approach of hearing evidence from not only male workers but also their wives to determine what was a fair and reasonable wage for a working man to support a family of five.
Higgins’s ruling became the basis for setting Australia’s minimum wage standard for the next 70 years.
