Administrative Assistant

O2 Marine is Australia’s largest independent specialist marine environmental, engineering and metocean consultancy. We deliver the science that helps major projects proceed responsibly, supporting projects across offshore oil and gas, ports, defence and coastal development throughout Australia and internationally.

Due to continued growth, we are looking for an organised and proactive Administrative Assistant to join our Fremantle team.

This is a varied, hands-on role supporting our busy operations across administration, field logistics, document preparation, office coordination and general team support. If you enjoy variety, are highly organised and like being the person who keeps things running smoothly behind the scenes, this could be a great fit.

Based in our Fremantle head office and reporting to the Senior Administrator, you’ll work closely with our field teams, scientists, engineers and broader corporate team.

No two days will be exactly the same. Your responsibilities will include:

• Coordinating travel, freight and equipment logistics for field operations

• Communicating logistics arrangements with field teams and supporting smooth project delivery

• Creating, editing and formatting documents, reports and PowerPoint presentations

• Maintaining company documents, templates and registers

• Coordinating meetings, office activities and internal events

• Managing office supplies, inventory and equipment maintenance

• Supporting visitor reception and general office coordination

• Assisting with employee onboarding, training logistics and HR administration as required

• Supporting compliance documentation and general administrative reporting

• Following O2 Marine's HSEQ requirements and promptly reporting hazards, incidents, near misses and improvement opportunities

We’re looking for someone who is organised, practical and comfortable juggling competing priorities in a busy environment.

Ideally, you will have:

• At least 2 years' experience in an administration, office coordination or similar all-round support role

• Strong organisational and time-management skills

• Excellent attention to detail

• Confident written and verbal communication skills

• Strong Microsoft Office skills, particularly Word, Excel, Outlook and PowerPoint

• The ability to prioritise and manage multiple tasks without losing attention to detail

• A proactive approach and willingness to help wherever needed

• Confidence working independently as well as part of a team

• Experience coordinating travel, logistics or field-based teams would be highly regarded

You’ll join a growing Australian business working on interesting and diverse marine projects across Australia and internationally.

We offer a collaborative and supportive working environment where you’ll have the opportunity to work across different areas of the business, build your skills and make a genuine contribution to the day-to-day success of our team.

If you're an organised all-rounder who enjoys variety, takes pride in getting things done and wants to be part of a growing specialist consultancy, we'd love to hear from you.
