Bachelor of Science (Marine Biology)

Marine Biologist: Marine biologists study ocean life and the ecosystems it depends on - from coral reefs and coastal zones to deep-sea habitats. You might research species behaviour, assess ecosystem health, or evaluate the impacts of climate change and pollution. Your work will contribute to conservation policy, reef restoration or marine sustainability, and might find yourself employed in research organisations, government departments, marine parks and universities. Typical salary: $78K in Australia.

Aquaculture Technician: Aquaculture Technicians support the sustainable production of seafood by monitoring water quality, maintaining farm systems, and caring for aquatic species. This role combines hands-on husbandry with environmental science. You could be checking oxygen levels in fish pens, managing breeding programs, or working with researchers to reduce disease outbreaks. Typical salary: $80K in Australia.

Environmental Consultant (Marine Focus): Environmental Consultants advise on the ecological impacts of coastal projects such as ports, aquaculture farms or marine parks. You'll conduct field surveys, write impact reports and provide recommendations to government or industry.

Science Communicator / Marine Educator: Marine Educators and Communicators share scientific knowledge with schools, aquariums, tourism operators and the public. You might run outreach programs, develop exhibits or design marine education resources.

Fisheries Officer: Fisheries Officers work for state and federal agencies to manage fish stocks and enforce sustainability regulations. Duties include inspections, patrolling coastal waters, and community education.

Research Scientist: Research Scientists investigate marine ecosystems, species and climate impacts through field studies, lab experiments and data modelling. You might study coral bleaching on the Great Barrier Reef, restore seagrass meadows in Gulf St Vincent, or trial sustainable aquaculture practices. Research roles often involve publishing findings, securing grants and collaborating with government or industry.
