Leadership
Guided from Australia, for Australian conditions
David Williams
Managing Director, GRAF Australia
David Williams has been Managing Director of GRAF Plastics Australia since 2015. Previously, the Welshman worked for many years for a GRAF partner in Great Britain before relocating Down Under with his family to lead GRAF Australia.
“Australia has a bit of everything: deserts, tropics, temperate zones, even snow. This diversity makes us unique and a pioneer. This means we have to adapt our products to make them work here as well.”
- Leads GRAF Australia from the Henderson, WA manufacturing site, with branches supporting Brisbane, Adelaide, Melbourne and Sydney.
- Focuses on adapting world-class German products to Australian soils, weather and council requirements, including flat underground tank installs for sandy Western Australian ground.
- Champions rainwater beyond garden irrigation: toilet flushing, laundry and broader water security education.

Together we support projects from domestic dwellings through to multi-dwelling, commercial and civil installations nationwide.
