For a few days in November, it will be illegal for people to carry certain household objects such as eggs and glass jars in central Brisbane or Cairns - unless they have a "lawful excuse".

This is because Queensland has passed a law setting out dozens of "prohibited items" that no-one will be allowed to carry in "security areas" during the G20 Summit.

In Brisbane, G20's designated security zone will include an area stretching north-south from Bowen Hills to South Brisbane, and extending west to Lang Park and east to Kangaroo Point.

Here are 17 of the prohibited items. Anyone carrying them could face a fine of up to $5,500.

1. The obvious stuff

Weapons, knives, antique firearms, replica firearms and explosives are all out. Smoke bombs too.

2. Shanghais, slingshots, swords and spearguns

3. Blowpipes

4. Handcuffs and whips

Hmmm. This could get interesting.

5. Bows and arrows

Prohibited: "A bow, whether a longbow, a compound bow or another type of bow."

6. Eggs

Prohibited: "Projectiles, including, for example, stones, ball bearings or eggs."

Also banned: glass jars and tin cans.

7. Big signs

Banned: "A placard or banner to which a timber, metal or plastic pole is attached or a banner more than 100cm high by 200cm wide."

8. Dangerous animals

Prohibited: "A reptile, insect or other animal capable of causing physical harm if released in close proximity to a person."

9. 'A thing capable of being used to climb a barrier'

Also: "A thing capable of being used to construct a stage, platform, tripod or tower or a structure similar to a stage, platform, tripod or tower, other than a camera tripod".

10. Loud noises

"A thing capable of emitting a sound loud enough to disrupt part of the G20 meeting, including, for example, a horn or a hand-held marine warning device."

And: "A thing capable of emitting a sound that can distress or upset a dog or horse."

11. Non-weapons that could hurt someone

"A thing that is not a weapon but is capable of being used to cause harm to a person."

12. Camouflage paint

Banned: "A thing capable of disguising or concealing the identity of a person including camouflage paint or cream, a mask or a balaclava, but not including headwear, worn by a member of a religious group, of a type customarily worn by members of the group."

13. Flotation devices

Also: "A manually operated surf ski or surfboard, kayak, boat or canoe."

14. Lasers

"A laser pointer" and "a laser device capable of being shone onto an aircraft or of projecting an image".

15. Kites

"A kite or other device suspended by airflow and controlled by a string or cord attached to it."

16. Remote-control cars - and drones

"A remotely controlled device, including a vehicle or a model of a vehicle, including, for example, any of the following operated by remote control: a toy car; a model plane; a drone or unmanned aerial vehicle."

17. Fake ID

"A thing purporting to be a Commonwealth accreditation or access approval, that is not genuine."

And: "A thing purporting to be an identity card for an appointed person or a police officer, that is not genuine."

What's not banned?

Surprisingly, given the security record at international political events in Australia, fake beards are not specifically outlawed.

What if I have a good reason to carry one of these things?

People can possess "prohibited items" if they have a "lawful excuse". Some examples of lawful excuses outlined in the legislation include:

a family using knives to consume food at a barbecue at South Bank Parkland;

a family using knives to consume food at a barbecue at South Bank Parkland; a child playing with a radio controlled toy car in the yard of the place where the child lives in a security area;

a child playing with a radio controlled toy car in the yard of the place where the child lives in a security area; a person who purchases a longbow from a sports store in a security area and then carries the longbow in a case to the person's vehicle to take it home.

And some examples it gives where there's no lawful excuse:
