This follows an agreement whereby Labor will direct its Senate preferences to the Greens in return for their directing lower-house preferences to the government.

The Greens' Paul Taylor will stand in Greenway, Debbie Robertson (pictured) in Chifley and Suzie Wright in Lindsay.

Mr Taylor is a full-time carer for his disabled father and said his experiences had driven his campaign for public health improvements.

He is also passionate about climate change.

``Make polluters pay, not households,'' he said.

``The Greens have proposed an interim carbon tax as a solution to the deadlock on emissions trading.''

Mrs Robertson wants more funding for mental health and dental services, public transport, education, housing and the disabled, protection of workers' rights and action on climate change.

Ms Wright, a former psychiatric nurse, is a social campaigner and environmental activist with an interest in climate change.

``Voters need to keep the pressure on governments to act honestly, with principle and to ensure that they act on their election promises,'' she said.
