Seafood and aquaculture are major industries in Australia
Aquaculture is Australia's fastest-growing primary industry, accounting for 34% of the total gross value of seafood production. The industry directly employed more than 7000 people in 2008, with an additional 20,000 indirect contributions. It is worth noting that aquaculture has a long history in Australia, dating back thousands of years to Aboriginal Australian peoples such as the Gunditjmara, who farmed short-finned eels in western Victoria, and the use of Brewarrina fish traps on the Barwon River in New South Wales.
Today, 10 species of fish are farmed in Australia, with southern bluefin tuna, Atlantic salmon, and barramundi being the most dominant in production. Other species include yellowtail kingfish, mulloway, and mud crabs, the latter of which has been cultivated for many years but sometimes leads to over-exploitation. Australia's aquaculture industry is expected to continue growing, with an overall real value projected to reach $2.21 billion by 2028-29. This growth is driven by increased production across various aquaculture species, particularly salmonids.
The Australian fisheries and aquaculture sector is highly regulated and managed by the Australian Fisheries Management Authority (AFMA) in Commonwealth waters, while State Fisheries agencies oversee commercial and recreational fishing within State waters. The National Aquaculture Council (NAC) also plays a crucial role in representing the industry at the political level and promoting best environmental practices through its voluntary Code of Conduct.

Australia has over 5000 species of fish
Australia is home to an incredibly diverse range of aquatic life, boasting over 5000 species of fish. This vast array of marine life is spread across various habitats, from the hot desert springs and freshwater rivers to the depths of the abyss in the deep sea. The number of fish species in Australia is ever-growing, with new discoveries being made each year.
Despite having such a large variety of fish, Australia's native freshwater fish diversity is relatively low compared to its land size. With only 281 described species, this can be attributed to Australia's arid climate, characterised by sparse rainfall and vast desert regions. In contrast, Australia boasts a higher diversity of saltwater fish species.
The freshwater fish fauna, while small in number, encompasses a unique range of species. Jawless lampreys, sharks, sawfishes, lungfish, eels, galaxiids, hardyheads, rainbowfishes, cods, grunters, gobies, gudgeons, and soles are just some of the fascinating freshwater inhabitants. Recent molecular studies have also uncovered several new freshwater species, enriching our understanding of Australia's aquatic biodiversity.
Australia's marine environment offers a stark contrast to its freshwater ecosystems. The saltwater realm boasts a higher diversity, with coral reefs, mangrove swamps, and seagrass meadows teeming with life. Among the myriad of saltwater species, some stand out for their culinary potential. The dark tail snapper, dusky groper, crimson snapper, Indonesian snapper, and long nose emperor are examples of underutilised fish with excellent eating qualities, as noted by Darwin skipper Grant Barker.
The fishing industry in Australia is highly regulated, with commercial and recreational fishing managed by authorities such as the Australian Fisheries Management Authority (AFMA) and various State Fisheries agencies. Seafood and aquaculture are significant industries, and fishing for marine and freshwater native fish is a popular pastime for many Australians.

Commercial fishing is managed by the Australian Fisheries Management Authority
Commercial fishing in Australia is managed by the Australian Fisheries Management Authority (AFMA), which was established in February 1992. The AFMA is responsible for the day-to-day management and compliance of Commonwealth fisheries, typically within the 200-nautical-mile Australian Fishing Zone (AFZ). The AFMA ensures that Commonwealth fisheries are managed sustainably for the benefit of all Australians, taking into account both the biological and economic consequences of fishing, including its effects on the broader marine environment.
The AFMA's operations are governed by the Australian Fisheries Administration Act 1991 and the Fisheries Management Act 1991. Under the Fisheries Management Act, the AFMA employs officers to undertake enforcement duties. These officers work independently and alongside the Maritime Border Command, the Royal Australian Navy, and the Australian Border Force to enforce fisheries laws. AFMA officers are empowered to make arrests, conduct searches, and carry defensive equipment, including body armour, telescopic batons, and handcuffs.
The AFMA also plays a role in combating illegal fishing in Australia's Exclusive Economic Zone (EEZ), which extends to 200 nautical miles from its coastline. The EEZ includes the waters between Australia and Indonesia and the Southern Ocean and extends to the Australian territories of Ashmore and Cartier Islands and Heard Island and McDonald Islands. The AFMA works closely with the Australian Border Force to protect Australia's marine resources and ensure the sustainable use of fisheries.
In addition to its enforcement and protection efforts, the AFMA promotes the efficient management and sustainable use of Commonwealth fish resources. The AFMA provides resources such as licensing forms, catchwatch reports, fisheries logbooks, and management booklets to support compliance with fisheries regulations. The AFMA also encourages the public to report any illegal or suspicious fishing activities to help protect fish stocks for future generations.

Australia's marine environment covers an area of about 9 million km2
Australia's marine environment covers an area of about 9 million square kilometres, making it the world's third-largest marine jurisdiction. This vast marine jurisdiction encompasses a diverse range of ecosystems, from tropical to subantarctic climate zones, including the mainland, Tasmania, and offshore islands.
The country's lengthy coastline of approximately 50,000 kilometres is characterised by unique oceanographic features. The western coastline, influenced by the Leeuwin current, and the eastern coastline, dominated by the East Australian Current, both experience poleward-flowing boundary currents. These currents play a crucial role in transporting warm water from tropical to temperate regions, which significantly impacts the distributions and seasonal migrations of marine species.
The marine environment in Australia supports an abundance of species, with surveys suggesting the presence of at least 250,000 species. This impressive biodiversity includes invertebrates, plants, and fish. In a study of the Great Barrier Reef (GBR) shelf seabed, which spans 200,000 square kilometres, over 7,000 species were identified. This highlights the richness and complexity of Australia's marine ecosystems.
Australia's marine realm is dynamic and subject to climate-driven changes. With rising sea surface temperatures, species redistributions are becoming more common. Around Australia, at least 198 marine species across 9 phyla are adjusting their distributions, with 87% moving poleward. These shifts in species ranges are driven by the warming of the oceans, which absorb over 90% of the additional heat trapped in the Earth's atmosphere.
Recreational fishing is a popular activity along the Australian coast and in the marine environment. It is valued at approximately $1.5 billion per year and is linked to benefits for health and well-being. The economic value of recreational fishing is evident in location-specific estimates, such as the $1.3 billion attributed to Victoria and $5.1 million to southern bluefin tuna fishing in the same state.
