“I’ve been working in Australia for more than 20 years and this billboard in Melbourne was a waste of money and a disgrace.

It was an appalling example of how the advertising industry treats its workers and the public,” he said.

Mr Baird said the billboards were “not just a waste but a travesty”.

“The advertising industry has no place in Australia and I hope we see more and more people standing up for the Australian way of life,” he told ABC Radio Melbourne.

“The way that people are being treated in the advertising sector is not what the Australian public want.”

The Advertising Standards Authority (ASA) is investigating the billboard.
