The remarkable progress that has been witnessed in the physical and material wellbeing for most Australians over the 20th century has not been paralleled by gains in the mental and subjective wellbeing of the population. General practice plays a strategic role in Australia's primary health care, which has been recognised as an essential health system that is able to deliver health to the population in a timely and equitable manner (World Health Organisation [WHO], 2008). General Practitioners are unable to provide adequate care to people experiencing a severe mental illness without support from specialist mental health professional such as a mental health nurse in the practice. The mental health nurse incentive program (MHNIP) offers opportunity for mental health nurses to work collaboratively with GPs in primary health care in the delivery of care to people with a severe mental illness.
