Indesco enters liquidation after Sellick Consultants deal

Indesco Pty Limited has been placed into creditors’ voluntary liquidation after key parts of the 40-year-old engineering consultancy were acquired by Sellick Consultants, preserving parts of the business while leaving the legacy corporate entity to be wound up.

Ezio Senatore of Eddie Senatore Advisory was appointed liquidator on 12 May 2026 after members resolved to wind up Indesco. The liquidation follows a transaction with Sellick Consultants, another ACT-based engineering firm, to acquire key parts of Indesco’s business. Indesco said the transition was intended to retain staff, preserve technical capability, and ensure continuity for clients and active projects.

Founded in 1983, Indesco grew into a multidisciplinary engineering consultancy with operations across the Australian Capital Territory, New South Wales and Queensland. The firm employed about 120 staff across offices in Canberra, Newcastle, Melbourne, Brisbane, Parramatta and Wollongong, and worked on projects in Australia and Southeast Asia.

The firm specialised in civil engineering and land development services, including project management, construction-phase services, structural facade engineering and traffic engineering.

Indesco’s project history included major public, residential and health-sector developments, including the Queanbeyan Civic and Cultural Precinct, the Affinity apartment tower in Broadbeach and an expansion of Brisbane’s Princess Alexandra Hospital.

Indesco director Angus Gorman said the Sellick transaction followed “a period of uncertainty” and would allow teams operating within Indesco to remain together and continue servicing clients and projects, subject to the resolution of relevant client and contractual arrangements with Sellick.

Gorman and fellow Indesco director Anna Nagalingam are expected to take senior leadership roles with Sellick as the Indesco entity is wound up. The arrangement allows for a transfer of operating capability, personnel and client relationships into Sellick, while the liquidator investigates the affairs of the company left behind.

The size of any creditor shortfall is not yet clear. Senatore said his investigation into Indesco’s debts and the circumstances leading to the liquidation was ongoing, and that he was still reviewing the company’s position.
