We are looking for an organised and proactive Office Manager to oversee the day-to-day administration and business support functions of Northern Territory Developments Ltd.
Working closely with the Director and Project Lead, you will help ensure our financial administration, project records, HR information and compliance systems remain accurate, organised and up to date.
Key Responsibilities
* Manage day-to-day bookkeeping administration using QuickBooks and Tradify, including supplier invoices, receipts, reconciliations, customer invoicing and credit control.
* Prepare information for CIS, VAT, payroll and regular financial reporting.
* Maintain accurate project files, drawings, specifications, quotations, variations, approvals, certificates and handover documentation.
* Monitor project records and expenditure and support the Director with regular management information.
* Maintain Tradify and SharePoint/Microsoft 365 records, including site photographs and key construction documentation.

About You
You will ideally have experience in office management, business administration, bookkeeping or a similar multi-functional role.
You should be highly organised, accurate and comfortable taking ownership of recurring tasks and deadlines. Good bookkeeping, invoicing and Microsoft Office skills are important, alongside the ability to learn new systems and improve administrative processes.
Experience within construction or trades, or knowledge of QuickBooks, Tradify, SharePoint, CIS, payroll, HR or health & safety administration, would be advantageous but is not essential.
This role involves access to confidential financial, commercial, project and employee information, so a high level of discretion and professionalism is essential
