Queensland Health Minister Steven Miles will lead the states in calling for an increase in the number of psychology sessions covered by Medicare to help stop mentally unwell patients overloading public hospital emergency rooms.

The proposal, recommended by the Productivity Commission in its draft report on mental health released on Thursday, is part of a broader push for more federal funding for mental health they will make at a Council of Australian Governments meeting in Perth on Friday.

For his part, federal Health Minister Greg Hunt will ask the states, which are responsible for hospitals, to build dedicated youth mental health wards and improve post-discharge care for mental health patients.

"We should be tracking, with the consent of individuals, with support services for every single person in Australia who's been discharged from a state hospital for suicidality or suicide attempt when they're in the recovery phase," Mr Hunt told Sky News on Thursday.
