The Anglican leader has achieved notoriety using the sign outside his Central Coast Anglican church to criticise Australia's detention, climate and social policies.

Father Bower's signs outside the Newcastle diocese Gosford Anglican Church have championed marriage equality - "Dear Christians. Some ppl are gay. Get over it. Love God." - gun reform - "When will they love your kids more than their guns?" and the environment - "There is no planet B".

But it is his passionate advocacy on behalf of asylum seekers and against their detention that put him in direct opposition to current Prime Minister Scott Morrison and Home Affairs Minister Peter Dutton.

Fr Bower's campaign against right-wing politics became national news when he branded then-immigration minister Peter Dutton "a sodomite" after the Queensland MP suggested detained asylum seekers were economic migrants.

Fr Bower hopes to win an upper house seat in May's federal election as part of Independents for Climate Action Now (ICAN) - a party which wants to work with both sides of politics to push Australia towards renewable energy.

"Climate change is the greatest human rights issue we will face in this century," he told AAP while launching the party in Sydney on Monday.

"Unless we get this right, it doesn't matter what else we get right."

ICAN see itself as a circuit breaker in Canberra appealing to voters who want science to trump the divided and paralysed major parties.

"We hope to bring a less divisive spirit into the parliament," Fr Bower said, adding he'd work with any party who supported "good climate policy".

"We want to draw the left and the right of politics together to inform good climate policy and good social policy so we can move forward as a people."

ICAN members are bound only by a requirement to observe scientific findings, particularly about climate change, founder Jim Tait says.

"Beyond the binding climate policy, we are a party of allied independents," the NSW Senate candidate told AAP.

"Our representatives are free to pursue what policies are in the best interest of their constituents."

Mr Tait, an environmental scientist who's worked as a consultant for both government and the private sector, wants Australia to transition toward 100 per cent renewable energy.

"We believe we can do it in a decade if we maintain the levels of investment we've enjoyed in recent years," he said.

"Australia is one of the windiest and sunniest inhabited continents in the world and we can use that to develop a renewable energy powered super-economy."

ICAN believes regional voters - experiencing dry rivers, ongoing drought and declining manufacturing sectors - will be won over by the benefits of renewable energy.

"We're talking about putting investment into the regions to solve this problem," the party's founder said on Monday.

In an interview with the Newcastle Herald last year, Fr Bower questioned the "concerning influence" of the "Christian right" in Australian politics and was disturbed by evangelical Christian Scott Morrison's first speech to Australians as prime minister last week. Mr Morrison said fairness in Australia meant "a fair go for those who have a go".

It is a definition of fairness that excludes many marginalised and disadvantaged Australians, but it reflected the prosperity theology that informed the pentecostal Christian church Mr Morrison attended, Father Bower said.

Prosperity theology was developed in America and holds that if humans have faith in God he will deliver security and prosperity.

Father Bower said such a view "sanctified" trickle-down economics and created "a very dangerous mix that will continue to marginalise the poor and benefit the rich".

"It consecrates a whole social and economic system that continues to widen the gap between rich and poor," Father Bower said.

"It does seem a Christian right element is becoming a concerning influence, and even a force, within Australian politics."

The party also includes Annette Schneider, a member of the Knitting Nannas protest group which opposes coal seam gas in regional NSW.

She told AAP she had risked her body and freedom for climate change awareness and would endure a stint in politics if it helped secure a future for subsequent generations.
