About the Project

The project operates within the Rail Plant Operations environment, supporting the delivery of large-scale infrastructure and operational works. It involves coordinating multiple stakeholders including project managers, subcontractors, suppliers, clients, and regulatory bodies to ensure project objectives are met efficiently and in compliance with company standards.

A strong focus of the project is on financial governance, reporting, and operational efficiency, ensuring accurate cost tracking, timely payments, and effective management of subcontractor claims and supplier relationships. In addition, the project requires adherence to strict health, safety, quality, and compliance frameworks, alongside maintaining effective communication across all parties involved.

The project environment is fast-paced and deadline-driven, with a high volume of transactional and administrative activity that supports overall project performance and successful delivery outcomes.

About the role

The Site Administrator plays a critical support role within the project team, responsible for delivering comprehensive administrative and financial coordination services.

Key Responsibilities

Managing purchase orders, subcontractor payments, and invoices, ensuring all financial transactions are accurate and processed on time

Supporting month-end processes, including cost reporting, reconciliations, and financial tracking

Assisting with project reporting, including monthly reports, progress claims, and project valuation data

Maintaining and updating financial systems and databases (e.g., JDE), including supplier setups and cost codes

Monitoring cash flow, debtor ledgers, and credit applications, while assisting with debt collection activities

Ensuring smooth document control and communication across stakeholders

In addition to financial responsibilities, the role acts as the central administrative hub for the site by:

Coordinating meetings, taking minutes, and managing correspondence

Overseeing office operations, supplies, and general management requirements

Supporting health, safety, and compliance systems (e.g., Pegasus)

Managing building access, facilities issues, and general logistics

Role Impact

This position is essential in ensuring that the project runs efficiently by:

Providing accurate financial control and reporting

Supporting project teams and leadership with timely information

Maintaining strong relationships with clients, subcontractors, and internal stakeholders

Enabling compliance with company policies and regulatory requirements

The role requires a high level of attention to detail, organisation, and the ability to manage competing priorities in a fast-paced environment, while working both independently and collaboratively.

Experience & Capabilities

A valid C‑class WA driver’s licence is mandatory.

Previous experience in project and/or site administration, ideally within the rail, construction, or large infrastructure sectors.

Experience in workforce mobilisation and onboarding processes, including compliance and safety requirements.

Experience with the Rail Industry Worker (RIW) system or equivalent industry competency platforms is desirable.

Experience supporting site operations such as procurement, reporting, documentation control, and cost tracking.

Strong background in financial administration, including high-volume documentation handling, invoicing, and cost-related processes.

Ability to work effectively in fast-paced project environments, adapting to changing priorities and demands.

Strong organisational and time‑management experience, managing multiple priorities with accuracy and efficiency.
