A Liberal backbencher has used parliament to slam the state of politics in Australia and his government's "top-down" approach to developing policy.
John Alexander took his fight for housing affordability a step further on Monday night, attacking the negativity he believes has engulfed the political landscape.
He said Malcolm Turnbull's declaration that there's never been a more exciting time to be an Australian and his positive "jobs and growth" mantra were a "world away from how our country's politics has actually played out in recent times."
The political contest was now one of constant negativity and a race to the bottom - where if you're not the biggest loser then you're a winner, he told MPs.
"It's negative politics triumphing over the positive development of policy," the outspoken MP said.
"But at what cost? Australians now, justifiably so, are uninspired and disappointed by our major parties and are deserting us by the legion."
Recent polling and reports have shown up to 25 per cent of Australians were voting for minor parties.
"We're at breaking point," Mr Alexander said.
"What seems to be dominating is unilateral top-down policymaking as opposed to evidence-based policy development by via public inquiries that are instigated by members of parliament after consulting with their communities."
The former professional tennis player has been pushing the government to act on housing affordability and has put forward a range of ideas.
But he said movement on the issue was too slow and too late, "delayed by politicians playing politics".
"We are creating public policy based on staunched, unflinching philosophy and sticking with it to the bitter end - an inflexible rod to beat the other side with.
"Many on this side of the house have repeated the same kind of inflexible conviction that the only issue here is one of supply - something which is patently wrong."
Australians were being put off by major parties because of their inflexible ideologies as much as the vitriol in interactions with each other, he said.
"The greatest challenge of our major parties must now address the recognition of their ceaseless negativity."
