Australia's biggest mountain range is underwater; deep-sea "restaurants" exist where the world's largest animal feeds; and our own "Grand Canyon" is buried beneath the waves near Perth.
A new report released this week, Atlantis Found: Underwater Icons of Australia's Unique South West (10MB pdf), uncovers 10 hotspots for unique marine life off Australia's largely unknown South West coast, stretching from Geraldton to Kangaroo Island.
Atlantis Found, issued by the Save Our Marine Life alliance of 11 leading conservation groups, reveals an underwater world rich with life, including Australian sea lions, green turtles, deep-diving sperm whales and unique and vulnerable reef fish such as the dhufish and breaksea cod.
The full-colour, interactive 'flip book' also identifies the South West as a rival to the Great Barrier Reef in importance for marine life.
"Up to 90 per cent of marine life in Australia's South West marine region is found nowhere else in the world. There is a greater lever of unique marine life in the South West than on the Great Barrier Reef," said Michelle Grady of the Pew Environment Group.
The 10 hotspots revealed in Atlantis Found include:
- The Abrolhos Islands-Situated 70 kilometres off the coast of Geraldton and home to the major breeding grounds of the iconic Western rock lobster.
- Perth's Grand Canyon-Located offshore from Perth, it is larger than the Grand Canyon, and is a feeding ground for the world largest animal, the blue whale.
- Geographe Bay-Hugs Bunbury and Busselton and is a well-known pit stop for humpback whales.
- Diamantina Fracture Zone-Australia's biggest mountain range sitting in 7000 metres of water; the Zone runs parallel to the coast from Augusta almost to Esperance.
- The Albany Canyons-Sperm whales, southern right whales and endangered orange roughy found here.
- Recherche Archipelago-Composed of 105 islands extending south from Esperance and home to 1200 species, including the leafy sea dragon.
- Kangaroo Island Canyons and Pool-50 kms from Kangaroo Island, a "restaurant" hot spot for rare whales.
Atlantis Found also highlights the need for large marine sanctuaries in Australian waters. "Less than 1 per cent of this South West region, spanning 1.3 million square kilometres, is protected against threats like ocean pollution from oil drilling and overfishing," said Tim Nicol of the Conservation Council of Western Australia.
Save Our Marine Life is calling on the federal government to create a network of large marine sanctuaries in Australia's South West. "There is a now a consensus of marine scientists that sanctuaries are the best way to protect our marine life and provide safe havens for fish stocks to recover from overfishing," said Mr. Nicol.
Atlantis Found also reports that marine sanctuaries make economic sense. Independent economic research by the Allen Consulting Group predicts that marine sanctuaries in the South West would lead to rapid tourism growth for the region, injecting up to $55 million per year into the Western Australian economy.
