Giving everyone access to public housing regardless of income is part of a multi billion dollar construction program the Greens want introduced to help mitigate an economic downturn from the coronavirus outbreak.

The $27.9 billion housing trust would build 500,000 solar-powered homes over the next 15 years and would boost jobs, clear the waitlist of those needing housing and cause rents to fall in major capital cities, Greens leader Adam Bandt told The Sydney Morning Herald and The Age.

Mr Bandt said he wanted the Morrison government to consider the proposals ahead of revealing a multibillion-dollar stimulus package this week, adding it would create 40,000 jobs including 4000 apprenticeships in the "green construction sector".

The public housing created through the trust would initially be made available to those on state and territory waiting lists and "would then be available to everyone in future," he said.
