Your Pet Just Went Missing? Do This First
Winter is a surprisingly common time for pets to slip away: storms spook dogs, doors get left ajar against the cold, and a bolted cat can vanish in seconds. If your dog or cat is missing right now, the next few hours matter most. Here is exactly what to do, followed by the microchip rules that quietly decide whether your pet actually makes it home.
The First 24 Hours: A Simple Action Plan
Work through this list in order. Most reunited pets are found close to home, so start there before casting a wide net.
- Search your immediate street first, calling in a light, happy voice and carrying strong-smelling treats. A frightened animal often hides nearby rather than running far.
- Phone every local vet clinic, animal shelter and your council pound. If your pet is handed in, a scanned microchip is how they will contact you, so ring around even if no one has called you yet (RSPCA Australia).
- Search petaddress.com.au with your microchip number to confirm which registry holds your details, then log in and mark your pet as missing so vets and councils are alerted (NSW Office of Local Government).
- Post clear, recent photos to local community and “Lost Pets” Facebook groups for your suburb and state, plus PetRescue’s lost-and-found listings.
- Leave a worn item of your clothing or your pet’s bedding just outside your door: the familiar scent can draw an anxious pet back overnight.
- In cold or wet weather, treat it as urgent. Small dogs, cats, senior pets and short-coated breeds lose body heat quickly and can become dangerously chilled if stuck outside all night, so it is worth continuing to search after dark.
The Microchip Is Your Pet’s Ticket Home, and It’s the Law
A microchip is a rice-grain-sized implant placed under the skin between the shoulder blades. It stores a unique ID number, and when a vet, shelter or council scans it, that number links to your contact details in a registry. Importantly, it is not a GPS tracker and will not show you where your pet is right now (RSPCA Australia). What it does is prove ownership and get you a phone call the moment your pet is scanned.
Microchipping is now compulsory for cats and dogs in every state and the ACT: New South Wales, Victoria, Queensland, South Australia, Western Australia and Tasmania. The Northern Territory has no territory-wide requirement, although the City of Darwin requires it under its own by-laws (RSPCA Knowledgebase). RSPCA SA puts the average cost at around $45, sometimes including registration, and discounted microchip days can be far cheaper.

The Catch That Trips Up Thousands of Owners
A microchip only works if the details attached to it are current. Researchers have warned that thousands of Australian pets could end up with “useless” chips if a private registry holding their details shuts down, and noted there are no rules governing how private registries operate (The Conversation). Out-of-date phone numbers and addresses cause the same dead end. Take five minutes today: search your chip number on PetAddress, confirm your phone and address are right, and update them the instant anything changes (NSW Office of Local Government).
A microchip proves who your pet belongs to, but it will not stop them wandering. A secure cat enclosure or catio and a GPS tracking collar tackle that side of the problem, while staying on top of vaccinations protects a pet that does get out and mixes with strays.
Frequently Asked Questions
Does a pet microchip track my dog or cat’s location?
No. A microchip is passive technology that only holds an ID number read by a scanner; it has no battery and no GPS, so it cannot show your pet’s live position (RSPCA Australia). For real-time location you need a separate GPS collar or tag.
My pet is chipped but I’ve moved house, is that a problem?
Yes, and it is one of the most common reasons reunions fail. If the phone number or address on the registry is out of date, a scanned chip leads nowhere. Update your details whenever you move or change numbers (NSW Office of Local Government).
How much does it cost to microchip a pet in Australia?
RSPCA SA puts the average at around $45, sometimes including registration, and discounted microchip events can be far cheaper (RSPCA SA).
