ACMA has declared three protection zones over cables of national significance in New South Wales and Western Australia.

Two protection zones are situated off the NSW coast. Both of these zones protect branches of the Australia Japan Cable network (linking Australia to Japan via Guam) and the Southern Cross Cable network (linking Australia to the USA via NZ and Hawaii). The NSW protection zones are:

the Northern Sydney Protection Zone, commencing at Narrabeen Beach; and
the Southern Sydney Protection Zone, commencing at Tamarama and Clovelly beaches.
A third protection zone, situated in WA, protects the SEA-ME-WE3 cable (linking Australia to South East Asia, the Middle East and Western Europe)

the Perth Protection Zone commences at City Beach in Perth, WA.
Each of the protection zones stretch from the shore out to a depth of 2,000 metres and extend one nautical mile either side of the cable. The Sydney protection zones also include the area between adjacent cables.

Within these protection zones, activities that pose a risk of damage to submarine cables are prohibited or restricted. Penalties apply for causing damage to a cable or contravening a prohibition, or restriction, in a protection zone. For further details on the protection zones, including a summary or full description of prohibited and restricted activities, detailed maps and further information about the protection zones, visit the Australian Communications and Media Authority or call 1300 856 337.

Purpose
This data and sets of maps was generate as inputs to the Futures of Seafood study State of Play (Work Package 1).Futures of Seafood delivers Australia's first comprehensive analysis of how intensifying ocean demands will reshape seafood production. This landmark 18-month study examines the cumulative impacts of competing ocean uses and policy decisions on the seafood sector. By uniting industry expertise with research capabilities, it creates a single source of truth about challenges and opportunities facing Australian seafood. Through spatial mapping, economic modeling, and social impact assessment, it provides decision-makers with essential insights for managing multiple ocean industries and ensures sustainable seafood production amid changing ocean access.
