The Customs (Prohibited Imports) Regulations 1956 are the principal Commonwealth instrument made under section 50 of the Customs Act 1901 that lists what may not be imported into Australia and on what terms. The body of the Regulations contains a small number of operative regulations and a large set of Schedules.
Regulation 3 prohibits the importation of goods specified in Schedule 1 absolutely. Regulation 4 prohibits goods in Schedule 2 unless the Minister or an authorised person grants written permission, and prohibits goods in the second column of Schedule 3 unless the conditions, restrictions or requirements set out opposite them are complied with. Regulation 3AA prohibits absolutely devices, and most documents, designed or customised to be used to commit suicide.
The Regulations then run through subject-specific permission regimes: objectionable goods (4A) including refused-classification computer games, terrorist-related material and prohibited symbols; plastic explosives (4AA); polychlorinated biphenyls (4AB); mercury, calibrated to the Minamata Convention (4AC); fish (4B and 4BA); asbestos (4C); tobacco (4D and 4DA); glazed ceramic ware (4E); firearms, firearm accessories, parts, magazines and ammunition (4F) tied to Part 2 of Schedule 6 and a public safety test (4FA); tablet presses and encapsulators (4G); other weapons (4H and 4HA); ice pipes (4I); woolpacks (4K); rough diamonds (4MA); radioactive substances (4R); and various sanctions schedules including UN-listed regimes (regulations 4Z series).
Regulation 5 controls importation of drugs listed in Schedule 4. Regulation 5A controls vaping goods. Regulations 5F, 5G, 5H, 5I, 5J, 5K, 5L and 5M cover kava as food, certain therapeutic substances, certain Schedule 8 goods, organochlorine chemicals, Chemical Weapons Convention compounds, ozone depleting and synthetic greenhouse gases, viable material from human embryo clones, and engineered stone benchtops, panels and slabs. Regulation 5HA gives a Ministerial reconsideration and Administrative Review Tribunal review path. Regulations 8 to 23 are transitional provisions for successive amending instruments. Regulation 6 makes clear the Regulations operate in addition to other Commonwealth importation laws.
