Sea dumping is any deliberate disposal into the sea of wastes or other matter from vessels, aircraft, platforms, or other man-made structures at sea. Deliberate disposal into the sea of vessels, aircraft, platforms, or other man-made structures at sea AND it is illegal without permits.
Waters surrounding Australia’s coastlines are protected from waste and pollution dumped at sea by the Environment Protection (Sea Dumping) Act 1981 (Sea Dumping Act).

The Sea Dumping Act regulates the loading and dumping of waste at sea and the creation of artificial reefs in Australian waters. Australian waters stretch from the low-water mark of the Australian shoreline out to 200 nautical miles (nm). It also includes any waters on the continental shelf of Australia where it extends past 200 nm. It does not include waters within the limits of a state or territory.
Australian waters do not include those within the limits of a state or territory. Waters within state and territory limits were set out in Letters Patent issued by the Governors of each of the states as they were being formed. The limits may include:
State limits are generally low water along the coastline together with bay closing lines (usually of no more than 6 nm in length) and river closing lines. Along some coastlines, locating these boundaries may be difficult, especially where islands lie very close to the coastline and certain bays. There are detailed legal principles that must be applied to determine the exact location of the state limits.
Defining waters within the state limit can be complex. You may need to seek legal advice to determine these limits. We will help you where we can.
The Convention on the Prevention of Marine Pollution by Dumping of Wastes and Other Matter 1972 (the London Convention) is an international treaty that has been in force since 1975 to protect the marine environment from human activities.
The London Protocol builds on the Convention and will eventually replace it.
The London Protocol aims to:
Australia became a Party to the London Protocol in 2000. The London Protocol commenced on 24 March 2006 and there are 55 Parties to the London Protocol.
Under the London Protocol, all dumping is prohibited, except:
Australia fulfils its international obligations under the London Protocol through the Sea Dumping Act. Australia reports annually to the International Maritime Organization on all permitted sea dumping activities in Australian waters or by Australian flagged vessels overseas.
If you are proposing to dump waste into the ocean, please see How to apply for a sea dumping permit.
Ensure both you and your crew are aware and educated on the strict laws surrounding Sea Dumping and that your SMS reflects the legislation and your procedures correctly and efficiently.
It is ALL our responsibility to ensure our oceans remain healthy to ensure the longevity of our industry and planet.
