Healthy North Coast

GP Advisers

North Coast Primary Health Network has employed GPs across its footprint to advise the PHN on a range of topics and to facilitate GP engagement across a range of activities.

These doctors will also assist NCPHN’s Clinical Councils and provide advice on clinical governance and professional development matters.

Marion Tait

Dr Marion Tait, Northern Rivers

For Marion, growing up in a rural medical family meant that dinner conversation was always interesting. She describes it as ‘a slow maturing of a very tough constitution for discussing lots of gory things while eating delicious food!’

It is no surprise then that after school, Marion decided Oceanography / Meteorology was how best she could serve humankind. Her greatest scientific contribution to the world was to do with the formation of Antarctic Bottom Water (yes there is such a thing!), but she said she just didn’t have enough facial hair to continue down this stream.

And so to Medicine – Marion completed a post-grad course in its infancy at Flinders University. After two years of city living she felt a desperate need to be somewhere smaller, and finished her degree in the Northern Territory.  She has also been privileged to work for North Coast GP Training as a registrar, board director, medical educator and supervisor.

Marion ‘absolutely loves’ her work at Casino AMS, working with a fabulous team for a great community, and is looking forward to conversations with NCPHN staff.


Dr Brett Lyman

Dr Brett Lynam, Tweed Heads

Brett has 30 years experience working across primary health care domestically and abroad. He has worked in rural and remote Northern Queensland and has a special interest in Aboriginal health. Brett also has strong expertise in public health and worked as a Senior Medical Officer in community-based vaccination programs, services for the disabled and elderly, integration of Community Health and hospital programs.  In addition he worked as an Associate Lecturer for the Royal College of Surgeons in Ireland where he lived for 12 years.

Brett now works in a busy general practice in Tweed Heads and is dealing with the challenges of NSW/Qld border practice. He’s enthusiastic about improving health care outcomes through integration and better coordination of health services.

A keen cyclist, when Brett’s not working you will find him in the hills on two wheels, enjoying the beautiful North Coast.


Gull Herzberg

Dr Gull Herzberg, Mid North Coast

Gull completed his BSc(Hons) at UWA  in 1986. He lived, worked and travelled overseas for a decade before returning to Australia and doing his medical training in the Graduate Medical Program at Sydney University. He lives and works as a GP in Bellingen. He has a strong interest in systems improvement, from the level of the individual GP, through the practice and up to regional and beyond. He has always had a keen sense of how people can work better together and enjoys helping this happen.

He has clinical experience in rural and metropolitan hospitals, mental heath and aged care facilities, palliative care and youth health.

Gull was integral in developing and implementing a system of improved care  for residents and staff in aged care facilities now in place in some RACFs on the Mid North Coast.  He was the initial headspace GP in Bellingen and is now on the team at Bellingen’s Youth Hub Clinic.

His clinical interests include youth health, mental health and Integrative Medicine. He is particularly keen to hear from and work with any or all interested GPs and others involved in primary health care. He looks forward to helping to improve the health of our community through his work with NCPHN and would welcome ideas and suggestions.



Jenny Beange

Dr Jenny Beange, Clinical Advisor, Port Macquarie

Jenny Beange began a career in general practice in Sydney before moving to Dubbo in 1988 to continue as a GP there.

As her interests diversified, Jenny took  up positions in Women’s Health, Drug and Alcohol, Aboriginal Health, Youth Health and teaching. Jenny continued part time in clinical practice until 2012, and  now works  as a general practitioner in Port Macquarie and in headspace Port Macquarie.

Following her passion for system reform and health equity, Jenny sought opportunities in health service governance, management and development; first as CEO of Dubbo/Plains Division of General Practice, Director and Chair of General Practice NSW, followed by appointment as CEO of Western NSW Medicare Local and interim CEO of Western NSW Primary Health Network. Moving to a person-centred system of care is fundamental to her vision for health improvement and system sustainability.

Jenny’s understanding of global approaches to primary health, particularly as they relate to the relationship between health and social care, has led to a number of international study tours to learn about alternative approaches to health innovation and integration. This has included meeting with health leaders in Scotland, England, Denmark, Spain, Finland and New Zealand.

Jenny has held many representative positions on councils, committees and advisory bodies at the local, state and national level, and has recently been appointed to the Mid North Coast Local Health District Board.
