What is a Marine Scientist?

A Marine Scientist studies life in the ocean and its connected waterways. They look at how marine animals and plants live, grow, and interact with each other. Their research helps protect ocean health and guides decisions about fishing, conservation, and coastal care.

Marine Scientists work in labs, on research vessels, and at coastal field sites. They plan experiments, collect samples, and analyse data. They also publish findings that inform government policy and conservation programs. A strong base in biology and data analysis is key to the role.

Day-to-day tasks include collecting water, sediment, and biology samples from the ocean. Marine Scientists run species surveys and track the effects of pollution on marine life. They build long-term programs to follow changes in ecosystems over time. Working with other researchers and government agencies is a regular part of the job.

With oceans under growing pressure from climate change and human activity, demand for skilled Marine Scientists is rising. The role offers a mix of fieldwork and desk-based research. It suits people who enjoy science, the outdoors, and solving complex environmental problems.

Career snapshots For Marine Scientists

Marine Scientist is a specialist science role with strong job prospects across Australia. Around 760 people work in this field nationally (Jobs and Skills Australia, ABS 2021 Census). Queensland has the largest share at 33%, followed by Western Australia at 24%. Future demand is rated as strong, driven by growing investment in marine research and conservation (yourcareer.gov.au, 2025).

Most Marine Scientists work full-time. Around 74% hold full-time roles, with an average of 41 hours per week (ABS 2021 Census). Median weekly earnings are $1,948, equal to about $101,000 per year (yourcareer.gov.au, 2025). The median age in the field is 41, and women make up 44% of the workforce. Over 63% hold a postgraduate degree, making this one of the most highly educated groups in Australia.

What will I do?

Marine Scientists study and protect ocean life. They research marine organisms and their world. They use their findings to guide conservation and wise use of the sea. Their work blends hands-on fieldwork with lab analysis and reporting.

  • Collecting ocean samples – Marine Scientists gather water, sediment, and biological material to check ecosystem health.
  • Conducting species surveys – They document and track the range of marine life across different habitats.
  • Tracking pollutants – They measure the impact of pollutants on marine animals and plants.
  • Preserving specimens – They collect and store unknown species and disease samples for further study.
  • Analysing data – They use computers to process results from field and lab work.
  • Assessing new species – They study how non-native species affect local ecosystems.
  • Building monitoring programs – They set up long-term systems to track pollution and environmental change.
  • Advising on fisheries – They provide guidance to help manage fish populations sustainably.
  • Contributing to conservation policy – They help develop marine conservation and aquaculture policies.
  • Recommending better practices – They advise industries on how to reduce harm to marine habitats.

What skills do I need?

Marine Scientists need a blend of science knowledge and hands-on skills. A solid base in biology is key, mainly in marine ecosystems and the species within them. Strong data collection, analysis, and reporting skills are vital to every research project. Technical writing is also needed to share findings with scientists and policy teams alike.

Beyond technical skills, Marine Scientists need strong problem-solving and thinking skills. They often tackle complex environmental challenges where the data is incomplete or unclear. Good teamwork and communication skills are vital, as most projects involve working with other researchers, agencies, and the public. A genuine passion for the ocean and a drive to keep learning are traits shared by successful Marine Scientists.
