While the dumping of material in the sea is now restricted, historically, the disposal of
unwanted waste in the ocean has been a common international practice. The ocean was long
considered to have an unlimited absorptive capacity, ensuring that any dumped waste would
have only a very localised effect. Moreover, the material w a s d e l i b e r a t e l y d u m p e d
well away from human activity. Many items, including boats, chemicals, ammunition,
inorganic waste and other hazardous material were dumped in the world’s seas often with
little understanding of the possible danger to human safety and the ecology of the sea.4
There was no expectation that the dumping areas would be exploited for their resources
at some point in the future. In the early 1970s, fishing trawlers operating at a depth over
120 metres were considered to be working in ‘very deep water’. Today, however, trawlers in
Australian waters work in depths to 1500 metres and material dumped in previous decades
has been accidentally recovered. Such recoveries attracted public attention in 1972–1973
when several drums of industrial waste were recovered by trawlers off Sydney. There were
immediate moves to limit sea dumping, culminating in the introduction of the Environment
Protection (Sea Dumping) Act 1981. Currently, most permits are issued solely for dredge
spoil disposal and for the creation of artificial reefs.5
During World War II chemical munition stocks were held at many sites around Australia.
Japanese expansion had reached as far as Papua New Guinea and Japanese forces had been
known to use chemical weapons during the fighting in mainland China. For its part,
Australia had reserved the right to use chemical weapons in order to retaliate. The stocks of
chemical munitions in Australia were held under General MacArthur’s Chemical Warfare
Plan for the South West Pacific Area (SWPA). Although their use was dependent on the
joint agreement of General MacArthur and the Australian Prime Minister, the stocks were
stored in Australia under US Army, Royal Australian Air Force (RAAF), Australian
Army or Navy supervision. None of the chemical warfare materials stockpiled in Australia
were used during combat and at the end of the war the material required disposal.6
This report, based on Australian and US government records and other published
material, surveys where chemical munitions have been dumped in Australian seas and
precisely what quantities have been dumped.7
The report also examines what may have
happened to the containers after they were dumped, including the corrosion rate of the
cylinders/munitions and the breakdown of mustard gas.8
It is vital to know precisely
where chemical weapons may lie, both to prevent human contact and to assess the possible
ecological consequences.
