Organisation Green Roofs Australasia (GRA)


GRA was a founding member nation when WGIN formed and we have remained active members to this day.

GRA is a not-for-profit membership organisation with an elected regional (Australia, New Zealand, the Philippines) committee which has become the peak industry body engaging with government & educational institutions, building industry disciplines, commercial & industrial sectors and the general public.

Our task is to disseminate information on green roof/wall science, technology, research, best practice, regulations and policy to assist in the complete transition into a green economy.

Our goal is to raise awareness about the profound economic, social & environmental benefits to be realised by incorporating green infrastructure into the urban fabric.

The GRA vision is "to promote the incorporation of green roof and green wall infrastructure into the built form" whilst also building affiliations that promote urban green infrastructure and sustain eco-system services.

GRA has held six Australasian Conferences which have always delivered highly regarded presentations from Regional University Research Academics, International Keynote Speakers, Policy Advisors, Design & Construction Professionals and Advocates for the Industry including Trade Shows with the latest technology.

In 2014, GRA will host the World Green Infrastructure Congress in the beautiful City of Sydney. The Congress will incorporate world leaders from all disciplines of the green infrastructure industry to promote the urgent need for a green economy transition to ensure the well being of future generations and our environment. There will be business opportunities, knowledge gained, City Tours & Entertainment plus discounted Post Congress Australian Holidays will cater for everyone - from leisure to adventure.
