Subsea cables connecting Aussies to the rest of the world

In 2007, the Australian Communications and Media Authority (ACMA) declared three submarine cable protection zones in Australian waters over submarine cables of national significance, including:

• the Submarine Cable Northern Sydney Protection Zone extending from Narrabeen beach to 40 nautical miles off shore covering northern branches of the Australia Japan Cable and Southern Cross cable, including the area between these two cables; and
• the Submarine Cable Southern Sydney Protection Zone extending from Tamarama and Clovelly beaches and extending 30 nautical miles off shore covering the southern branches of the Australia Japan Cable and Southern Cross cables, including the area between these two cables.
• the Submarine Cable Perth Protection Zone stretching from City Beach, near Perth, to 51 nautical miles offshore (that is, to a water depth of 2000 metres) for the protection of the SEA-ME-WE 3 (SWM3).

Most of submarine cables connecting Australia land within the submarine cable protection zones in Northern Sydney, Southern Sydney and Perth.

Additionally, the government authority of the Sunshine Coast Council launched Sunshine Coast International Broadband Submarine Cable network, and built a government-owned submarine cable landing station in Sunshine Coast, Queensland.
