Meet the sustainable development experts
We’re NGH —a national environmental, planning and advisory consultancy guiding Australia toward a more sustainable tomorrow.
For over 30 years, we’ve upheld our reputation for providing progressive, collaborative and comprehensive consultancy services that achieve the exceptional. From day one we’ve gone beyond the expected, pioneering renewable energy and sustainable infrastructure services across regional and metropolitan Australia. Equipped with interdisciplinary expertise, we tackle challenges creatively and practically, delivering positive, flexible and impactful solutions that will endure for years to come.
At NGH, collaboration is at the heart of everything we do. We work in partnership with our clients, our communities and our industry’s changemakers to shape a sustainable future for everyone. Because our nation is changing. It’s evolving faster than ever before, and we’re determined to facilitate this transformation, conscientiously. We’re navigating our tomorrow — supporting every stakeholder, facing every obstacle and redefining outdated practices to guide our nation toward a brighter, more sustainable future.
As a company, we take great pride in our contributions to some of Australia's biggest infrastructure projects and our ongoing leadership in the development of the growing renewable energy industry. While our origins lie on the New South Wales South Coast, we have since evolved into a dynamic and forward-thinking consultancy that is committed to delivering balanced and practical solutions Australia-wide.
Our vision is to be a significant driving force in the transition to a sustainable future, and we are dedicated to achieving this through the work we do. We strive to attract exceptional individuals who share our passion for meaningful projects that prioritise the preservation of our natural, cultural, and social resources.
Our core values of equality, respect, collaboration, and support are the pillars upon which we operate, and we endeavour to embody them in all aspects of our work

Our guiding principles
To be an influential leader in the transition to a sustainable future based on science and ethics.
To empower our team to deliver innovative, ethical, and comprehensive projects, whilst fostering collaboration and partnership ensuring benefits for our clients, community, and environment.
Our commitment to reconciliation
“I am a proud Wiradjuri woman who was born in Cowra, New South Wales and I am part of the very large Murray, Gordon, and Jeffries families. I grew up hearing Dreamtime stories from my wonderful Grandparents about the importance of caring for our earth and how our people shape one of the most sustainable cultures in the world.
Feeling connected to my Country is important to me, and I feel working in this industry has completely aligned both my professional and personal values.
NGH provides me with a culturally safe working environment, and it is a place where I can be who I am without discrimination or judgement. I believe celebrating, preserving, and connecting with our First Nations culture are genuine priorities for NGH and I have never been prouder to be part of this organisation.
With the implementation of a RAP, this will formalise what we are already trying to achieve as an organisation but will also fundamentally strengthen our relationship with our communities and support all our staff in their understanding of the importance of true reconciliation.”
