Canning MP Andrew Hastie has hit back at the Greens party, calling members "nuts" following protests outside his Mandurah office this week.
The Greens, along with other community groups, say they are lobbying to stop the Liberal's AUKUS deal - which would see Australia's first nuclear-powered submarines in WA waters under a partnership with the United States and United Kingdom.
The AUKUS deal plans to give access to cutting edge military to Australia from the UK and US with constructing nuclear powered submarines being the first step.
Defence spending would be increased to fund the submarines and boost Australia's long-range strike capability including Hawk and Tomahawk cruise missiles.
The nuclear submarines with unlimited range will not require reactors in Australia and don't need refueling, with sealed modules for the vessels to be sent from the UK or US.
On Friday, Greens MP Jordon Steele-John, former MP Jo Vallentine, and Conservation Council nuclear free campaigner KA Garlick presented a dossier of statements to Mr Hastie - who is also Assistant Defence Minister.
The dossier outlined anti-AUKUS statements from groups such as the Australian Conservation Foundation, the Medical Association for the Prevention of War, the International Campaign against Nuclear Weapons, and Amnesty International.
Mr Steele-John said the Liberal government was trying to implement the AUKUS deal for two reasons alone.
"To be able to escalate tensions so they can use the threat of war to win an election and because their party takes money from the very weapons manufacturers that will profit from these projects," he said.
"The Morrison government is engaged in war mongering with China and the Assistant Defence minister and the Defence minister are complicit in that war mongering.
"They're using a faux threat of war for political purposes and it is a shameful thing to do."
Mr Steele-John said the Liberals had proposed to base the nuclear submarines in WA with no community consultation, without mediating the danger, and without detailing how much money it would cost.
But Mr Hastie ignored the protests saying "the Greens crazy talk on AUKUS shows they are not living in reality".
"The Chinese Communist Party is undertaking the biggest military peacetime build-up since the 1930s," Mr Hastie said.
"Last year they issued a list of 14 demands to Australia - what parts of our sovereignty does senator Steele-John think we should give up?"
Mr Hastie said nuclear submarines were critical to Australia's national security and was great news for WA in regards to job creation and investment in the defence industry.
An 18-month consultation period for the nuclear submarine deal would determine workforce and training requirements, production timelines and safeguards on nuclear non-proliferation agreements.
During this time, The Greens say they will continue to protest the AUKUS nuclear-powered submarine deal.
