About the Company

Our client is a highly successful, fast-paced business that plays a vital role in South Australia’s infrastructure boom. Specializing in the supply chain for major civil construction projects—think roads, rail, and earthworks—they are the reliable backbone for tier-1 contractors across the state.

Based in the western suburbs, they have a tight-knit, down-to-earth team that values autonomy, hard work, and a good sense of humor. They are now looking for an experienced, adaptable Office Manager to take ownership of their headquarters and keep the business running like a well-oiled machine.

The Role

As the Office Manager in an agile business, you will be the heart of the business. This isn't just a receptionist role; you will wear multiple hats, handling everything from high-level office administration and basic bookkeeping to supporting compliance and contract administration for major civil projects.

If you love variety, enjoy taking full ownership of your workspace, and want a role where your impact is visible every day, this is your next move.

Key Responsibilities

• Financial Administration: Manage end-to-end Accounts Payable and Receivable, follow up on invoices, and assist with monthly payroll preparation using Xero/MYOB.

• Project & Supply Support: Assist project managers with civil contract documentation, tracking supply orders, and coordinating delivery paperwork.

• Office Coordination: Maintain a clean, efficient office environment, manage supplier relationships (IT, utilities, facilities), and order office/kitchen amenities.

• Compliance & WH&S: Assist in maintaining company certifications, updating safety registers, and ensuring subcontractor compliance documentation is up to date.

• Executive Support: Provide ad-hoc administrative support to the Managing Director, including managing calendars and preparing meeting agendas.

What We Are Looking For

• The Mindset: Proven experience as an Office Manager, Senior Administrator, or Bookkeeper within a small-to-medium business environment.

• Industry Context: Experience working within civil construction, logistics, manufacturing, or trades is highly advantageous. You know how to talk to site managers, truck drivers, and corporate clients alike.

• Tech Capabilities: Strong proficiency in cloud-based accounting software (Xero or MYOB) and advanced skills in the MS Office Suite.

• Autonomy & Drive: A self-starter who doesn't need micromanaging. You see a gap, you fill it; you see a problem, you fix it.

• Organization: Exceptional time-management skills with the ability to pivot when urgent project requests land on your desk.
