Sam Ferguson is the Sustainable Australia Party candidate for Maitland

He is also passionate about protecting the environment and wants to stop over-development and corruption.

"I believe the time is right for a national conversation about the population target of this country," he said.

"For too long, we have increased the population to prop up house prices and GDP (gross domestic product), without considering quality of life or essential services."

The Sustainable Australia Party has a policy that wants Australia's population to be under 30 million by 2050, by capping immigration and providing universal access to contraception.
