Once the Writs have been issued for a State election, and commencing on the 40th day before election day for a Local Government election, all posters must show the name and address of the person authorising the printing of the poster, and the name of the printer and the address at which it was printed. These requirements give authenticity to the document and allow the source or printer to be contacted, if necessary. This provision applies whether a poster is displayed on a building, a motor vehicle, attached to a wooden stake or is in banner form.

It is an offence to write, draw or depict any electoral matter directly on any roadway, footpath, building, vehicle, vessel, hoarding or place.

The size of posters is only regulated when they are displayed in certain areas at a polling place on election day. Posters are prohibited within 6 metres of the entrance to a polling place (the actual building). Posters displayed beyond the 6 metre exclusion zone and up to or on an outer wall, fence or other boundary to the grounds are not allowed to be bigger than 8,000 square centimetres (80cm x 100cm) in area. Several single posters of the required size must not be joined together so as to create a sign in excess of the legal maximum size.

Posters are not to be exhibited on or in unoccupied premises, unless permission has first been obtained from the owner. It is also unlawful to attach posters to telegraph poles without the written consent of the appropriate electricity provider.

If the Returning Officer receives a complaint concerning an illegal poster outside a polling place, the candidate, registered political party or community organisation will be contacted and asked to remove it. Election officials are able to remove such posters displayed at a polling place.
