Our Ambassadors
Rozanne Biddle

Rozanne was born with her right hand and forearm missing although the cause remains unknown.
She was actively involved in all aspects of primary school life – elected as a school counsellor and faction captain, narrated a school musical and tried her hand at hockey, tee-ball, netball, swimming, and basketball.
Through high school, Rozanne balanced academics, a busy social life, sports, and a casual job. She graduated as an occupational therapist in 1996, building a career in workplace rehabilitation, helping people with disabilities, illnesses, and workplace injuries return to work.
From the beginning, her husband saw past her limb difference and has provided unwavering support and confidence in her abilities. They have two teenage children.
Now a business owner and occupational therapist, Rozanne provides workplace rehabilitation services to employers and clients while also assisting veterans in accessing household services. She is also exploring opportunities to support NDIS participants in pursuing their sports and fitness goals.
In 2025, Rozanne aims to apply for NDIS support to (hopefully!) experience life with a bionic arm. She is training for the Hyrox fitness racing competition in the Adaptive Athlete – Upper Limb division and her goal is to cross the finish line and successfully master the burpee with one hand.
Passionate about advocacy, Rozanne’s mission is to empower individuals with hand differences to live independent, limitless lives and she is eager to support research for Aussie Hands.
Dave Serpell

Dave was born on ANZAC Day 1999 and is a dedicated Ambassador for the Aussie Hands Foundation. Living with symbrachydactyly—a condition affecting his right hand, leaving him with a thumb and little finger—Dave has been part of the Aussie Hands community since its early days, inspired by his mother’s founding vision.
As a young adult, he remains committed to supporting others with hand differences, particularly children and youth navigating challenges at school and beyond. Dave offers mentorship and shares his experiences to help young people build confidence and resilience.
A passionate professional, Dave balances his time between the disability sector and the automotive industry, where he runs a Turo business renting out premium vehicles—a reflection of his lifelong love for cars. Above all, he cherishes his role as a proud husband to Lana, whom he met through Aussie Hands, and a devoted father to their young son Jeremiah.
Spending quality time with his family is what drives him, whether it’s enjoying good food, music, or unwinding in places like the hilltops, snow, beach, or tropics. With a heart for making a positive impact, Dave is dedicated to advancing support for others and creating a brighter future for his family and the community he holds dear.
Aussie Hands is also seeking new Ambassadors to represent Aussie Hands.
The Ambassadors will be involved in a wide range of activities which will enhance the profile of the Foundation by engaging regularly with members and raising awareness of hand differences in the Australian community.
Expressions of interest are to be emailed to info@aussiehands.org.
