Contract Administrator in Gold Coast

Sunbuilt is a Southeast Queensland head contractor delivering residential high-rise and development projects across the Gold Coast region. We're known for disciplined commercial and contractual management, strong site delivery teams, and a collaborative approach with our clients, consultants and subcontractors.

We're seeking an experienced Contract Administrator to join the site team on a landmark 34-storey, 154-unit residential high-rise development in Southport. The project has completed its podium and is now progressing through its typical floor cycle. This is a high-profile opportunity to play a key role in the contractual and commercial delivery of a major Gold Coast tower, working alongside an established project management, design and site delivery team.

Key Responsibilities

• Administer subcontract packages in accordance with head contract and subcontract terms, including assessment of claims, variations and extension of time (EOT) submissions.
• Manage the verbal instruction workflow — ensuring site instructions are logged in Procore, formalised in writing, and acknowledged by subcontractors within required timeframes.
• Prepare and issue formal correspondence, notices and instructions in line with contractual obligations and timeframes.
• Support procurement sequencing and trade package administration in coordination with the project management team.
• Work closely with Project Engineers to ensure a clear delineation between contractual administration and technical/programme delivery.

• Attend and contribute to weekly site and project meetings, including action tracking and follow-up.
• Lead procurement activities, including subcontractor and supplier engagement, tender evaluations and commercial negotiations.
• Manage project cost control, forecasting, budget tracking and commercial reporting, and assist the Project Manager in preparing monthly reports for the client.
• Proactively identify, assess and manage commercial and contractual risks across the project.
