Background

Background

This 10-hectare site in Wetherill Park, Western Sydney, was a former landfill with significant contamination issues, environmental risks, and limited development appeal. But where others saw a liability, we saw an opportunity. Over the last 15 years, REGENESIS led the remediation and transformation of McKay Close into a thriving industrial precinct, with more than 20,000m² of gross lettable area now built and in use.The site is owned and managed by REGENESIS and available for tenants.

The Challenge

The Challenge

Remediating a former landfill is a complex challenge. The site was heavily constrained by landfill gas, contamination, and the complex regulatory frameworks of the EPA and Fairfield Council. At acquisition, it was considered high-risk and low-value — unsuitable for conventional development.

Turning it into a functional and compliant industrial site required long-term commitment, regulatory navigation, and a deep partnership with technical experts in environmental science and civil engineering.

Ongoing adaptation through
Ongoing adaptation through a feedback loop that allowed lessons from each stage to improve the next, refining planning, environmental controls, and development approaches as the project progressed.
Staged development delivery
Enabling part of the site to be activated while long-term works continued on the remaining parcels.
Tenant-led design
With several facilities co-designed for specific operational needs, reflecting the precinct’s flexibility and commercial value.

The Impact

The Impact

The land has been successfully stabilised, remediated, and stands as a model for the transformation of complex brownfield site.

  • A remediated, stabilised industrial precinct that has overcome the legacy risks of a former landfill.
  • Over 20,000m² of prime industrial floor space delivered, supporting logistics, manufacturing, and resource recovery.
  • A diverse and growing tenant base, proving the site’s flexibility and market appeal.
  • A replicable model for the transformation of complex brownfield sites into income-generating, environmentally responsible assets.
  • A major uplift in land value and contribution to the local economy — demonstrating how long-termthinking, technical rigour, and partnership can turn even the most challenging sites into valuable industrial assets and a commercial success story.
