What is a Major?
A major is your primary area of focus within a degree. It determines the core subjects you'll study and the skills you'll master.

Major overview

Study marine biology and help protect the world’s oceans and marine life

Explore life beneath the surface and learn how marine ecosystems function, adapt and respond to change. In the Marine Biology major within our Bachelor of Science (Environmental and Conservation Sciences), you’ll develop practical skills in industry-standard laboratories equipped with world-class research instruments, alongside immersive field experiences in coastal and marine environments.

Throughout your marine science course, you’ll investigate biodiversity, ecology and ocean processes, building a strong understanding of how these systems operate and how they can be managed and conserved. Your learning is grounded in hands-on lab work and field-based study, reflecting real scientific practice.

You’ll also take part in field research camps, with opportunities to study coastal ecosystems at Point Peron or coral reef environments in Coral Bay, applying your skills in real-world settings.

You can broaden your expertise by combining this major with others such as Conservation and Wildlife Biology or Environmental Science and Management, developing a well-rounded understanding of environmental and conservation science across land and sea, preparing for a rewarding career in marine science.
