University of New England logo

We have partnered with UNE to support a student through the GEG Indigenous Scholarship. UNE are committed to access, support and creation of opportunities for those who might not otherwise be able to take advantage of university and higher education. The scholarship has provided the recipient with many opportunities, removing the financial burden that would have been faced otherwise.

Indigenous Employment

We offer an inclusive work environment and encourage Indigenous people to apply for positions within our organisation. Send your CV or apply for vacant positions advertised.


This painting is by William Ingram, a Dunghutti man loaned to us by Tranby.

It represents the importance of community education for making Aboriginal peoples strong and connected.  The incomplete circles show the gathering of how we do education around the country and as we connect together, we become complete (in the centre). This is a painting that reflects the importance of self-determination and cultural education that is Aboriginal-led. This is how we build strong communities.

Our Commitment to Quality

We have robust systems in place to deliver on the promise. We keep up to date with industries best practice to ensure we are giving you quality outcomes. Our Quality, Safety & Environment Systems, are certified to stringent JAS-ANZ standards.

Our Beginnings

Grosvenor Engineering Group began with three university friends who had studied engineering at the University of New South Wales, two of which are still Owners / Directors today – Nicholas Lianos and Peter Souflias.

Nicholas came across Grosvenor Air Conditioning, a company looking to sell its HVAC maintenance contracts and with his university friends they bought the contracts. In May 1994, the Grosvenor Group of companies began with a team of 13. Today we are a team of 800, with customers spanning across Australia and New Zealand.
