National Health Reform Agreement (NHRA)

Under the new Labor Prime Minister, Julia Gillard, the commitment for the Commonwealth to become the majority funder of public hospital services was modified. Under a Heads of Agreement on National Health Reform signed at the COAG meeting in February 2011, the Commonwealth promised to retain its base funding commitment as agreed; but from July 2014 funding would be limited to 45 per cent of the efficient growth in hospital services (based on an efficient price), rising to 50 per cent from 1 July 2017.

In August 2011, the National Health Reform Agreement (NHRA) was signed formalising the Heads of Agreement and replacing the superseded NHHNA. The NHRA detailed the new framework for the future delivery of funding for health and aged care services. This included the establishment of Medicare Locals, as well as new independent bodies to administer key financial arrangements. The NHRA retained the commitment to national ABF arrangements for public hospital services.

Clause A5 of the NHRA reiterated a Commonwealth guarantee to provide an additional $16.4 billion for hospitals between 2014–15 and 2019–20.

Changes under the Coalition Government

The 2014–15 Budget included an announcement that the ABF formula agreed to under the NHRA would be abolished from 2017.

This revised approach to hospital funding was expected to generate considerable savings, which the Parliamentary Budget Office estimated would total $56.2 billion to 2024–25.
