Tasman Fracture Marine Park lies off the south-west corner of Tasmania, complementing the Port Davey Marine Reserve which was proclaimed in 2005 by the Tasmanian Government. The Tasman Fracture Marine Park is scored by steep canyons, and encloses other geological features including steep escarpments, troughs, saddles, basins, seamounts and part of a plateau that is over 400 kilometres long and rises three kilometres above the seafloor. These features host spectacular deep-water coral communities, providing habitat for a rich diversity of marine invertebrates and fish species. The waters of the marine park are also home to many species of seabirds, seals and cetaceans such as dolphins and killer whales.

A deep reef biodiversity survey was carried out in the Tasman Fracture Marine Park in January 2009. The survey, jointly carried out by the NESP Marine Biodiversity Hub, CSIRO, National Science Foundation and Woods Hole Advanced Imaging and Visualisation Laboratory used a Remotely Operated Vehicle (ROV) to observe the marine life down to depths over 3800 metres.
Research
These short articles highlight the findings from ongoing scientific research within the Tasman Fracture Marine Park, including exciting new discoveries and ideas for future projects.
Small and/or camouflaged fish species hidden on or near the reef surface are commonly referred to as ‘cryptic’ or ‘cryptobenthic’ fishes. These species are characteristically difficult to see but are diverse and abundant throughout Australian Marine Parks and may play an important role in supporting the larger predatory fish species protected within park boundaries.
A collaborative research voyage on the state-of the-art research vessel RV Investigator in 2018 explored Tasmania’s hidden seamounts (under-sea mountains). Extensive areas of deep-sea coral reefs supporting diverse communities were surveyed, mostly between 700 and 1500 metres below the sea surface. These seamount reefs represent a globally significant reference site to monitor recovery of deep-sea coral communities following the impacts sustained from bottom trawling in the 1990’s. We now better understand the biodiversity and distribution of these vulnerable ecosystems and their ability to recover from impacts such as a bottom trawling.
Parks Australia manage 60 Australian Marine Parks, many of which include shallow reefs. These reef habitats are hugely diverse, and include tropical reefs dominated by hard corals; current-swept offshore bommies covered in sea whips, sea fans and soft corals; temperate rocky reefs with sea urchin barrens or low lying colourful seaweeds; and deeper rocky reefs with sessile invertebrates and large black coral trees.
In Autumn 2019, the Institute of Marine and Antarctic Science (IMAS) completed a two-week continuous multibeam mapping program in shelf waters of the Freycinet, Huon and Tasman Fracture Marine Parks to extend current knowledge of habitat distribution in these parks. In addition, several areas outside the park were mapped to provide external reference areas for the Tasman Fracture Marine Park. This mapping will underpin future biological inventory and monitoring programs.
Natural values
Our marine parks have a number of different values, including natural, cultural, heritage and socio-economic values. The natural values of our marine parks refer to the habitats, species and ecological communities within them, and the processes that support their connectivity, productivity and function. Below are the key datasets that help inform park managers about the natural values that exist within our network of Australian Marine Parks. For more information on other park values refer to the relevant park Management Plans on the Parks Australia website.

Maps
The information provided by these datasets was integral in the planning and development of our national network of marine parks. Learn in detail about how scientists and marine park planners used these important marine features together to design Australia's network of marine parks, or explore the datasets for the Tasman Fracture Marine Park individually through the links below.

Latest maps
Since the initial planning of the Australian Marine Parks Network in 2012, new mapping data has emerged that allows us to see in finer detail the features that exist within our parks. These datasets help marine managers to understand more about what's under the surface, where there are overlaying management or protection regimes, and/or where pressures on the marine environment may be increasing.
