Our Leadership Team

Louise Johnstone Forster
Chief Executive Officer (CEO)

As CEO, Louise is driven to lead changes that see improvements for the rights of older people in Western Australia, and to ensure Advocare offers its staff and volunteers a positive space to also make their contributions to this vital work.

Louise studied Anthropology in the United Kingdom, and attained vocational qualifications in adult education in Australia. In the last decade, she’s completed her Master of Business Administration and governance qualifications, which she uses for governance roles as well as her professional management and leadership roles.

Social justice is a core value for Louise. Anywhere she can contribute to work in this area is where both her head and heart can meet. Her goal is to leave this earth with a legacy of having made a positive impact on people and the community she lives within.


David Prestney
Corporate Services Manager

As Corporate Services Manager, David’s role is to ensure the ‘back-office’ functions such as Finance, Human Resources are working well and that special projects undertaken are implemented effectively to support all areas of the organisation. He’s committed to supporting and empowering Advocare’s front-line team day-to-day so they can continue to improve the lives of older Western Australians.

David has a Bachelor of Commerce from Curtin University. He started his working life in public practice accounting prior to entering commerce and working in various fields including financial services, technology and mining before joining the aged care sector. Over his career, David has also contributed to the smooth running of a number of fellow not-for-profit entities as a board member.

The importance of Advocare’s work to David is assisting people to navigate the complex path through life events and decisions, at a time when sometimes things don’t get any clearer or easier as we age. Our organisation’s strength to him is its ability to listen, support and assist older people as their issues arise.


Erin Timu
Development Manager

Erin has more than 20 years of experience working with peak bodies, professional services and small to large-sized, private organisations. She has extensive experience in community and regional development, stakeholder engagement, project management, leadership and marketing and communications.

Erin joined Advocare in 2021, drawn to the values of Social Justice, Empowerment, Integrity and Equity, and is committed to shining a light on the issues and challenges older Western Australians face.

As Development Manager, Erin leads our community development, volunteer and marketing teams. She is passionate about driving Work Health and Safety initiatives to support and increase the health and wellbeing of the Advocare team.  She looks forward to growing our brand and strengthening our community and stakeholder relationships to increase our support for older Western Australians.

Hazel McKenna
Acting Interim Program Manager, Operations and Advocacy

Hazel joined Advocare in 2019 and has worked across various programs supporting the rights of older people in Western Australia. With her in-depth knowledge and grass-roots experience working as a Senior Case Coordinator in Community Home Care she is excited to be taking on the interim role of Program Manager.  

In 2023 Hazel graduated from the Emerging Leaders in Governance Program from which she hopes to give back back to the community though participation on boards.

In her most recent role as Senior Project Officer, she worked closely with OPAN in the design and delivery of the Home Care Check-in Pilot.  Through this she gained a greater understanding of the barriers older people experience, how ageism impacts quality of life and wellbeing and the importance of a trauma-informed approach to care and service provision.

In the interim period, she hopes to assist Advocare to continue meeting its strategic objectives and shine a spotlight on the outstanding service that Advocare provide to older people in Western Australia, extending our reach to ensure that more people are aware of the assistance available to them.
