Local laws that catch crew out in Sydney

Smoking and vaping are banned in all enclosed public areas in NSW, including shopping centres, cinemas, libraries, trains and buses, and in a list of outdoor ones: within 10 metres of children's play equipment in outdoor public places, at public transport stops and platforms including ferry wharves and taxi ranks, within 4 metres of a pedestrian access point to a public building, at public swimming pools, at spectator areas of sports grounds during organised sport, and in commercial outdoor dining areas.

Vaping is treated on the same terms as tobacco throughout, and NSW Health signage covers both. NSW Health inspectors conduct regular compliance monitoring and can issue cautions or on-the-spot fines of A$300. The outdoor dining rule catches people who assume a footpath table is outside the ban.

It is illegal to smoke or vape in a car with children under 16 in the vehicle. NSW Police enforce that one.

Every arriving passenger must complete an Incoming Passenger Card and present it with their passport. Meat, poultry, fish, seafood, eggs, dairy, fruit and vegetables must be declared, as must grains, seeds, bulbs, straw, nuts, plants and parts of plants, traditional herbs or medicines and wooden articles, and animals, parts of animals and animal products. Destination NSW warns that if you fail to declare items you may receive a significant penalty or be prosecuted with a criminal offence.

AUD$10,000 or more in Australian or foreign currency equivalent must be declared. So must goods obtained overseas, or bought duty or tax free in Australia, with a combined total price of more than AUD$900, gifts included.
