Australia’s marine parks protect some of the most diverse and far-reaching ocean environments on the planet. Stretching from tropical reefs and coral atolls to cool temperate waters and deep offshore canyons, these parks safeguard habitats shaped by powerful currents, rich biodiversity and long ecological history. They provide space where marine ecosystems can function with minimal disturbance and where species have the chance to thrive.

Each marine park reflects the character of its region. Some protect coral reefs alive with fish and invertebrates, others conserve seagrass meadows, kelp forests or vast pelagic zones used by whales, sharks and migratory seabirds. Many areas hold cultural significance for Traditional Owners, carrying knowledge and connections that guide sustainable care of sea country. Together, these parks form a national network that supports marine life, strengthens ecological resilience and helps maintain the health of Australia’s oceans.

Here we highlight the importance of Australia’s marine parks, exploring the environments they protect, the species they support and the role they play in conserving the country’s marine heritage.
