Yes. Section 10C of the Domestic Animals Act 1994 requires cats and dogs to be microchipped as a condition of registration (which is compulsory once the animal is 3 months of age). However the requirement to microchip prior to sale/transfer under section 12A only applies to domestic animal businesses.
Regulation 12 of the Domestic Animals Regulations 2005 outlines what information must be recorded in the microchip database.
Section 12A (2) of the Domestic Animals Act 1994 requires an animal’s microchip number to be displayed in any advertisement for the animal, but not at the point of sale. If the seller is a ‘domestic animal business’ the breeder must display the microchip number or the breeder registration number, and the name of the issuing Council.
