Sustainability Awards 2020 Ambassadors

For the first time in its 14-year history, the Sustainability Awards will have ambassadors to help promote what has become Australia’s largest and most popular sustainability event for the built industry. These Ambassadors that we have chosen are not only leaders in their field, they are at the same time, veritable icons of the industry who have each contributed in their own unique way in helping and promoting sustainability and a better environmental outcome for all. Following are the bios of all five of our 2020 Sustainability Awards Ambassadors.
