About Us
The Austral team has grown steadily over our 48 years in business. Our strong staff retention is the result of several key factors, most importantly the way we treat each other—with fairness, respect, and a strong sense of teamwork. We are proud to be part of a greater team where everyone’s contribution is valued. Over the years, we’ve celebrated many great milestones, and we look forward to achieving many more in the future.
1977
Establishment
A Strong Foundation Since 1977
Austral Air Conditioning Services was founded by Mr. Gary Allen, who began trading in 1977 under the name Allen’s Installations. Initially focused on domestic ducted and light commercial systems, Gary’s vision and dedication quickly propelled the company into the large commercial sector, setting the stage for future growth.

1995
Steady Growth
In 1995, we began trading as Austral Air Conditioning Services Pty Ltd and expanded our operations to include a full-time Service Department.
This strategic move allowed us to offer ongoing support beyond installation, fostering long-term, successful relationships with our customers through reliable maintenance and responsive service.

2000
Regional Expansion
As opportunities arose beyond the Greater Sydney region, Austral successfully expanded its footprint across New South Wales and the ACT.
We have proudly delivered a range of major infrastructure, education, and defence projects, including:
Tamworth, Port Macquarie, and Manning Hospitals
Mid North Coast Correctional Centre (MCNCC) and Kempsey Correctional Facility
Therapeutic Goods Administration (TGA), Canberra
East Gungahlin School and Wee Waa School
Opal Museum, Lightning Ridge
BioResources Facility, Wollongong
University of Newcastle
These projects reflect our capability, adaptability, and commitment to delivering high-quality outcomes across diverse sectors and regional locations.
