Are there border checks when crossing interstate on trains in Australia?

Question

Specifically, from WA to SA to NSW

Answer 1

Yes there are. Don't try to smuggle things. Big fines.

Answer 2

No

Answer 3

Only for fruit and vegetables.  At border crossing they check cars and passengers for fruit and vegetables using sniffer dogs and manual inspections - you can't take these between states.

From WA Department of Agriculture.

Western Australia is free from many animal and plant pests, diseases and weeds found elsewhere in Australia. Quarantine restrictions apply to the movement of a range of goods between Western Australia and other states and territories, whether they be commercial goods or personal effects. These restrictions are in place to prevent the introduction and spread of many weeds, pests and diseases that affect agriculture, the environment and our way of life.

People travelling to Western Australia by air and rail are subject to Interstate Quarantine Passenger Clearance.

Quarantine inspectors meet the majority of interstate flights and the twice-weekly Indian Pacific.

Passengers are given the opportunity to dispose of fresh fruit, vegetables, honey and other plant products by surrendering them to a Quarantine Inspector, or by placing them in the Quarantine bins provided.

Specially trained detector dogs are used to identify quarantine risk items amongst passenger luggage and freight at the Perth Domestic Airport and at the Rail Terminal, assisting inspectors in finding undeclared risk materials. Import clearance of risk material is conducted through inspection on arrival.

The Indian Pacific Train

Quarantine inspectors board the Indian Pacific rail service approximately forty minutes before the train arrives in Perth. All travellers are required to declare fruit, vegetables, honey and plant matter for inspection. Goods that do not satisfy import requirements are seized.

So just make sure you eat all your fruit and honey for breakfast before you cross and you will be a-okay.

Answer 4

There might be... especially if you're entering South Australia or Victoria.  They're very worried about fruit flies, so any fruit or other vegetable matter will be confiscated if you haven't thrown it out already.

I'm not sure they'd be too worried about BB guns... so long as they are legal.

Answer 5

No plants. Interstate they are usually concerned about fruit carrying diseases e,g. fruit fly, from one area to another.
