Harold Mitchell's $12.5m for think tank MEDIA power broker and arts philanthropist Harold Mitchell is creating a new advocate for better health and education policy, donating $12.5 million over five years to fund an apolitical think tank in partnership with Victoria University. The Mitchell Institute for Health and Education Policy, to be launched today with former Labor finance minister Lindsay Tanner as chairman, will advocate practical "off-the-plan" policies for state and federal governments that redress inequitable health and education outcomes.
