Our team

The Gumala Trust (GIPL) is part of a larger team, the Gumala team! We work closely together with the Gumala Aboriginal Corporation, even working from the same Perth Office on Adelaide terrace. This is why, at our Annual General Meetings and other Gumala events, we all put on the same team shirts and work together to make the events run without a hitch.

This close relationship means that although we’re responsible for different things in the Gumala Foundation, we come together to work on projects that need both GAC and GIPL’s input. We need our entire Gumala team to help the Foundation thrive.

Overall, the Gumala Team is a big family, but the GIPL team itself is small, but mighty! Back in 2017, GIPL started with just 3 team members. We currently have 6 in our East Perth offices, and you can contact us at GIPL@gumalatrust.com for any GIPL or Investment related enquiries.


John Raftis is the Executive Officer for GIPL. He oversees both the GIPL team and the investments in the Future Fund. John works closely with the EO of Gumala Aboriginal Corporation, to jointly achieve maximum outcomes from the Foundation for our Beneficiaries and Members. He started with the Foundation in 2015 as a Chief Financial Officer, before taking on the role of GIPL EO in 2017.

He has a Bachelor of Business, Accounting, from Curtin and has been a registered Certified Practicing Accountant (CPA) since 2000. John is a fellow of the Governance Institute of Australia (FGIA) and won the WA Dux award for Corporate Governance in 2005.

Born in Perth, John went on to spend most of his childhood in regional towns, including Moora, Northam, Geraldton, Karratha and Port Hedland. Outside of work he likes to garden, cycle and spend time with his family. John is also a regular plasma donor with the Red Cross, and he completed his 100th donation in 2020.

Kirsty Whiteoak took on the role of Office Manager & PA in 2021. As the Office Manager she looks over the day-to-day operations of GIPL and assists both the GIPL Board and our EO as the PA.

She recently completed her Diploma in Project Management, has a Diploma in Leadership and Management and a FETAC level 6 (equivalent to an Advanced Diploma) in Supervision in Early Years.

Kirsty was born in the UK, and through her mum’s side has family spread across Austria and Serbia. Prior to her move to Perth in 2013, she lived in Ireland for 4 years. Kirsty loves to travel and has a keen interest in learning about different traditions, cultures and values.

Sarisa is responsible for the accounting and financial reporting function within GIPL, which includes providing accurate and timely financial reports for end-of-month and end-of-financial-year reporting periods. She enjoys being able to work independently and loves working with numbers. Sarisa started with the Gumala Foundation in the shared services team in 2015, before undertaking a role at GIPL as Finance Officer in 2017. In 2020 she progressed into her current role as Accountant for the GIPL team.

She completed her Bachelor of Commerce in Management and Marketing in 2007 and went on to complete her Master of Accounting in the following year, both at Curtin University. Sarisa has also been a Certified Practicing Accountant (CPA) since 2015.

Sarisa grew up in Nakhon Si Thammarat, in Thailand, before moving to Australia, which she loves. Outside of work she likes taking her family out to reptile centres and hiking trails, and loves finding new challenges for them to undertake together.

Briana Clements is our PR & Communications Officer, managing all corporate communications including making videos, managing GIPL’s social media and website, and curating annual reports and GIPL’s Gumala Newsletter contribution. She started this role in 2020.

She graduated from UWA with a Bachelor of Arts and first-class honours in Communications and Media studies, specialising in Transmedia, or cross-platform, storytelling/marketing. Briana has completed a course in Adobe InDesign CC and completed Cultural Foundations for Workplaces – Empowering Respect and Relationship, which was facilitated by Jolleen Hicks.

Briana was born in Perth, in the Kalamunda Hills, and went to Treetops Montessori School in Darlington, so she’s spent her whole life on Whadjuk Noongar land. During her school years, she travelled to Wyndham to help teach literacy to the local First Nations school children, and during her university years helped film and create a call-to-action video with FARA and UWA to allow them to gain the funding to undertake a research project on the industrial impacts on the Murujuga Rock Art. Outside of work, she loves all things creative and getting out with her dogs to explore the Perth Hills. She’s also currently undertaking a Certificate in Horticulture.

Kate originally started with the GAC finance team back in 2019, before undertaking a role in the GAC Projects team that managed the Housing Program rollout. She has now moved over to GIPL to take on a new role as our Property Management & Social Investments Project Officer, where she will be continuing to support the Housing Program.

As a Gumala Member, Kate really enjoys working in a job that supports her community, and she's excited to learn more about GIPL's Investments. Outside of work, Kate has two young boys, and you'll often find the family fishing, camping, or heading off on an adventure, as she loves to travel.

Jarryn has recently joined us as our Finance & Administration Assistant. He'll be working closely with our Finance Administrator, Sarisa Htay, and helping out around the office where he can. From Port Hedland, Jarryn is the youngest of three kids, and he enjoys hiking with friends in his time off.

He has a Certificate II in Business and is currently undertaking his Certificate IV in Accounting and Bookkeeping. With over 10 years of administration experience in both the public and private sectors, GIPL is glad to have him as a part of our team, and we're looking forward to seeing what he can achieve in the role.
