Our People

Drug Policy Australia’s Board of Directors is responsible for managing our day-to-day operations.

Our directors are supported by an Advisory Board comprised of several renowned drug addiction experts and reform advocates.

The Board

greg-chipp-professional.jpgGreg Chipp - Managing Director & Chairman

Greg has been actively involved in public policy development and advocacy since the 1970s, when he helped his father, Don Chipp, to establish the Australian Democrats.

He drives DPA’s policy development and strategic direction, work that reflects his long-standing personal belief in drug reform. In 2013, Greg ran for the Australian Senate to draw attention to the urgent need for new drug laws that protect and help people, rather than criminalising and persecuting them.

John-Sherman.jpgDr John Sherman - Founder and Director

As a medical doctor, John has spent decades treating and caring for drug users in St Kilda and Footscray. He currently runs a clinic that treats more than 1000 patients with pharmacotherapy substitute opiate therapies, including methadone and suboxone. This work means that John has a deep understanding of the effects drug dependency can have on users and their loved ones.

John provides DPA with advice on policy issues that reflects his extensive practical experience.

Lisa_van_Rooyen.jpgLisa van Rooyen - Director

Lisa joined the DPA board in 2020, bringing more than 20 years of experience in operations and organisational change management.

She is a long-term resident of inner Melbourne, which means she has seen firsthand the crippling effects of drug addiction. She has also witnessed the impact health services can have on people who use drugs, which has informed her belief that the best way to help is to support drug users, rather than to punish them.

He is currently Co-Chair of the International Bar Association’s Human Rights Institute (2018-).
Michael Kirby’s work on the global pandemic of HIV and membership of the WHO Global Commission on AIDS (1988-92) convinced him of the need for radical revision of national and international drug law and policy, which should align more closely with universal human rights, proportionality, and justice.
