Grant Stewart
Grant has a background in plumbing and education as well as strong links to WorldSkills. After competing at the WorldSkills competition in 1997, Grant has worked in many roles in WorldSkills up to Chief expert in Plumbing and now as Assistant Technical delegate for Australia. Grant worked full time as a Plumber and a Plumbing teacher in various regions of Australia throughout this time. Working in Zimbabwe on building classrooms, toilets and furniture projects in schools in the late 1990’s led to a strong interest in water and sanitation projects and the sharing of skills that continues throughout developing regions around the world.
Grant joined IAPMO in late 2013 and has worked with the World Plumbing Council, Healthabitat, RMIT and WorldSkills Foundation on many projects including Sanitation Studios in Nepal and the Community Plumbing Challenge in India, South Africa and Indonesia.

Adriano Pupilli
Adriano is committed to thoughtful design and architecture with a strong focus on people and place, believing that good design and innovation should be accessible to everyone, not just a privileged few.
Adriano Pupilli established his architecture practice in 2010 building on a wealth of experience gained locally and internationally working on private, public and humanitarian architectural projects. A key formative experience was working with Paul Pholeros both in his architectural practice and in Healthabitat. It was this role that would provide Adriano with first hand experience working with underserved communities in remote and regional Australia, Nepal, India and Indonesia. During this role Adriano gained a deep appreciation for the link between the built environment with the health outcomes of the occupants, and the responsibility we have as designers to the communities we work within.
Since 2010 Adriano has built a successful architectural practice delivering carefully considered residential, commercial and public projects to clients and stakeholders. During this time he has continued developing his passion for working with marginalised communities and to increase the agency of architects in service to a greater portion of society. Across all scales of projects Adriano’s design approach is people focused, creating living breathing buildings that promote occupant wellbeing and joy.

Sandra Meihubers AM Chair PPF
Sandra has spent much of her dental career working with Aboriginal people in Australia and has a deep commitment to delivering dental care and training to communities considered outside of the “mainstream”. She has been instrumental in establishing and running remote area Aboriginal community controlled dental services, training Aboriginal Health Workers in dental care and prevention, advising governments on policy, developing materials to support remote area dental practitioners and creating national and international networks of like minded practitioners.
Sandra has taught in TAFE and university dental programs and derives great satisfaction from watching the growth and development of confidence in people who sometimes undervalue themselves.
Since 2000 her skills and experiences, with a strong focus on projects developed and grounded in the target communities, have spread to projects in Nepal, Timor L’este and Bangladesh. The Nepal dental work has been married to a village based sanitation program since 2007, this “teeth and toilets” focus affording opportunities to address basic hygiene issues as well as providing the value added benefit of dental care.
In 2017 Sandra was appointed a Member of the Order of Australia AM.
