A "green stimulus package" that includes more spending on railway infrastructure and pay rises for public servants is being proposed by the Australian Greens to boost the economy amid fresh evidence of the collapse in inner-city apartment construction.

In the wake of this week's national accounts which showed the economy at its weakest since the global financial crisis, Greens leader Richard Di Natale said a bold approach was needed to weather the "economic storm" now facing the nation.

The economy expanded by 1.4 per cent over the past 12 months with growth centred on government spending and exports. Consumers and private investment continue to falter.

Senator Di Natale said bringing forward infrastructure, as backed by Reserve Bank governor Philip Lowe, and a lift in wages would deliver an immediate and long-lasting boost to the economy.
