Our diversified services include closure studies and decommissioning, deconstruction and demolition, civil engineering and construction, lanjdscaping and external works, resource recovery and waste management, asbestos removal and disposal, site remediation, rehabilitation and revegetation, and heavy plant rental.

With more than 30 years of experience, 1000+ skilled, qualified and trained staff, and Australia’s largest privately owned fleet of specialist machines, we have the scale and triple certified management systems to mobilise our people and plant to meet the demands of any project in any location – metro, regional, remote or marine.

Consolidated group turnover in excess of $640m per annum and a strong balance sheet reinforces our capacity to deploy capital in upgrading and expanding our fleet, as well as to offer bank securities, guarantees and/or surety bonds of 10% or more of the agreed contract sum to meet any project or site specific requirement.

  • Our services are available Australia wide

    • Delta Rent operates one of the largest earthmoving equipment rental fleets of more than 350 high performance machines in Australia. We understand that the deployment of heavy plant and equipment is high risk and capital intensive. It also requires specialist skills and operating licences. That’s why we are a trusted partner, not just for the rental of late model plant and equipment but exceptional service and 24/7 qualified support and personnel.
