According to the 2025 AIMS Index of Marine Industry, this surge was predominantly fueled by a resurgence in domestic tourism and an expanding natural gas industry. The marine sector now contributes $203 billion in total value added, accounting for 9.1% of Australia's Gross Domestic Product (GDP). This includes $140 billion generated across 19 industries and an additional $63 billion in indirect value added across 109 upstream industry groups.
Professor Selina Stead, CEO of the Australian Institute of Marine Science (AIMS), highlighted the significance of these figures, noting that the report showcases the marine industry's substantial economic footprint and its growing contribution to Australia's prosperity.
The growth in the marine industry has also led to a 52% increase in full-time equivalent jobs, totaling 712,000 positions. This employment boost is largely attributed to the return of international visitors and strong domestic tourism demand, as well as growth in the natural gas industry and water transport services.
Between the financial years 2021 and 2023, the economic output of the natural gas, offshore oil exploration, and extraction sector grew by 12%, reaching $122 billion and comprising more than half of the marine industry's economic output. Marine tourism and recreational activities also experienced significant growth, with a 65% increase over the same period, reflecting the recovery of the tourism industry following the COVID-19 pandemic.
Professor Stead emphasized that not only has the marine industry grown since the last index, but it has also expanded significantly over the past decade. Compared with the financial year 2012-13, the marine industry has grown to be 1.8 times larger in 2022-23, adjusted for inflation.
As the marine industry continues to thrive, it presents numerous opportunities for investors and stakeholders. For individuals considering financing options for marine ventures, understanding the industry's growth trajectory can provide valuable insights into potential returns and the overall health of the sector.
