Cool fact…
Satellite images have shown that Big Ben can occasionally modify the predominantly westerly airstream by affecting cloud formations for several hundred kilometres downwind of Heard Island.

Inner marine zone

The Inner Marine Zone provides for the management, and in some cases prohibition, of activities in the near shore (< 12 nm) marine areas of the Reserve, to ensure protection of the coastal environment of the islands, the near shore foraging areas of wildlife, and the values of that marine area.

Transport activities in the Inner Marine Zone, including vessel and small craft use and any discharges, will be regulated to prevent or minimise environmental impacts.

The outer boundary of the Inner Marine Zone also coincides with the outer boundary of the Territory, the HIMI World Heritage Area and the proposed HIMI Ramsar wetland area.

Zone Boundaries

The Inner Marine Zone comprises the marine waters of the Reserve extending from the high tide mark to the 12 nautical mile boundary of the HIMI territorial sea (view map).
