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.

We’re navigating our tomorrow — supporting every stakeholder, facing every obstacle and redefining outdated practices to guide our nation toward a brighter, more sustainable future.
Our guiding principles

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.
The implementation of our RAP formalises 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.”

It is International Women’s Day, a day to acknowledge the achievements and contributions of women throughout history.
This year’s theme is “Count her in”, emphasising the importance of counting in women and girls in all aspects of life, from data collection to decision making processes. The focus on counting in women is centred on the recognition that women and girls often face invisibility and marginalisation, which particularly shows up in data and statistics. Many issues, such as violence against women, economic disparities, and barriers to education, remain hidden or downplayed without accurate and comprehensive data.
As environmental scientists, we know better than most the importance of accurate data and the robustness that diversity brings.
I am extremely proud to lead an organisation where women are well represented at all levels:
🔹 Women represent 66% of all employees at NGH.
🔹 Women represent 74% of our leadership team from the Board down to Regional Managers, team leaders and in enabling functions.
🔹 Of our current graduate cohort of 15, 80% are women.
We are a company that supports and nurtures talent – regardless of gender.
While gender equality remains a critical topic, expanding the conversation to embrace diversity of thought, experience and background is imperative for innovation and growth. Creating an environment where individuals from all walks of life feel valued, respected
and empowered to contribute is key to our success
Over the next few weeks, you will see a different side of the amazing women at NGH. From skydivers to taiko drummers, photographers to scout leaders... each brings more than their gender to the table, they bring a wide range of diverse experience, backgrounds and
stories to share and contribute to the rich fabric of NGH.
We hope you enjoy these inspiring stories, Erwin Budde - NGH Chief Executive Officer.

There is a major shift afoot.
After three decades in the engineering sector’s shadow, environmental consulting firms are becoming a force in
their own right.
The growing emphasis on environmental sustainability, regulatory compliance, and social responsibility has fuelled
the demand for specialist environmental consulting services.
Gone are the days when merely obtaining the correct environmental reports were sufficient for project approval.
Today, the demand has shifted towards a comprehensive, multi-disciplinary approach that meets the ever-increasing demands from the community and facilitates project approval.
“Our clients are drawn to our project management and problem-solving capabilities, our specialised scientific
knowledge, our relationships with regulators, and our ability to bring multiple stakeholders together toward a common goal.” Erwin Budde, NGH CEO.

In December 2023, the NSW Government issued a renewed Aboriginal Heritage Impact Permit (AHIP) over Lake Victoria. This permit marks a significant step in safeguarding the area’s rich Aboriginal cultural heritage values.
Lake Victoria, a key part of the Murray-Darling Basin, is home to a cultural landscape rich with history, dating back 28,000 years. The lake’s shores are scattered with significant Aboriginal sites, including burials, middens, and stone artefacts, highlighting its profound cultural and archaeological importance.
Our heritage team undertook the Aboriginal cultural heritage assessment for this project working in partnership with stakeholders and the Aboriginal community. NGH’s innovative use of GIS-based modelling coupled with field survey has been instrumental in creating a framework for ongoing landscape management and conservation.
“The AHIP application was the largest in NSW, with over 1,000 sites being part of the landscape management.” Matthew Barber, Technical Director - Heritage
