Short answer: Yes
Yes. This obligation applies to maritime and ports whatever their structure or size. The deciding fact: Industry: Maritime & ports.
The obligation in brief
Comply with MARPOL — Protection of the Sea (Prevention of Pollution from Ships) Act 1983. The Protection of the Sea (Prevention of Pollution from Ships) Act 1983 (Cth) and AMSA's Marine Orders implement the International Convention for the Prevention of Pollution from Ships (MARPOL), the main international convention on ship-sourced pollution. Discharge requirements cover oil, noxious liquid substances, harmful substances in packaged form, sewage, garbage and air emissions.
Trigger: Operating a vessel or platform that generates oil residues, garbage, sewage or emissions, carrying oil, noxious liquid substances or packaged harmful substances, or being involved in a discharge or probable discharge above permitted MARPOL levels.
