Dog Microchipping in Australia: Everything You Need to Know
Mandatory in every Australian state and territory — costs, process, registration, and what to do when a microchip fails.
Microchipping is mandatory for all dogs in every Australian state and territory — fines up to $5,500 for non-compliance
The procedure takes seconds, costs $30–80 AUD at a vet or council clinic, and lasts your dog's lifetime
A chip is only useful if the registration details are current — update your address immediately every time you move
- 🇦🇺Mandatory in all 8 states and territories
- 💉Injected between shoulder blades — takes under 10 seconds
- 💰Costs $30–80 AUD depending on provider
- 📡ISO 11784/11785 standard — readable by all AU scanners
- ♾️Lasts your dog's entire life — no battery, no expiry
A microchip is a passive RFID transponder the size of a grain of rice. Injected under the skin between the shoulder blades, it stores a unique 15-digit code. When a vet, council ranger, or shelter scans your dog, that code links to your contact details on the national register. No chip means no way home if your dog is lost. It's also illegal.
lost pets in Australia are never reunited with their owner without microchip ID

Legal Requirements by State and Territory
Mandatory everywhere — no exceptions
Every Australian state and territory requires dogs to be microchipped by a specific age. Purchasing or selling an unregistered dog is also an offence in most states. Check your local council for registration fees — the chip implant and the registration are two separate steps.
| State/Territory | Required by age | Registration body | Council registration required |
|---|---|---|---|
| NSW | 12 weeks | NSW Pet Registry | Yes — within 28 days of chipping |
| VIC | 3 months | Pet Exchange Register | Yes — via local council |
| QLD | 12 weeks | Queensland Government | Yes — via local council |
| SA | 3 months | Dog and Cat Management Board | Yes — via local council |
| WA | 3 months | DogWA / CatWA | Yes — via local government |
| TAS | 6 months | Tasmanian Pointscore | Yes — via local council |
| ACT | 8 weeks | ACT Government | Yes — via Access Canberra |
| NT | 3 months | NT Government | Yes — via local council |
What Happens During the Microchip Implant
The process from start to finish
Injection between shoulder blades
Your vet uses a sterile preloaded syringe to inject the chip subcutaneously (under the skin) in the scruff between the shoulder blades. It's similar to a vaccination — most dogs barely react. No anaesthetic needed.
Immediate scanner verification
The vet scans the implant site immediately to confirm the chip is reading correctly and the number matches the paperwork. You receive a certificate with the 15-digit microchip number — keep this.
Register on the national database
Within the legally required timeframe (varies by state), register the chip number with your state's official registry and your local council. The chip is worthless without registration — it's just a number with no name attached.
Best time to microchip
Most vets implant the microchip at the same visit as the first vaccination (6–8 weeks). This means one vet trip, one injection event, and your pup is covered from day one. Reputable breeders and rescue organisations are legally required to chip before rehoming.
Where to Get Your Dog Microchipped
Only accredited implanters can legally chip your dog
In Australia, only vets and approved animal welfare officers are authorised to implant microchips. At-home microchipping is illegal. Verify any implanters credentials if using a non-vet service.
Registration: The Step Most Owners Miss
The chip implant and the registration are two completely separate steps. A chip with no registration is useless — the scanner reads a number, but there's no owner attached to it. Yet thousands of Australian dogs are chipped but unregistered, or registered to an old address.
Update your details every time you move
Moving house is the most common reason microchips fail to reunite dogs with owners. Your chip number stays the same for life — but your contact details don't. Update your state registry and council records immediately every time you change address or phone number. Most registries allow online updates for free.
Microchip registration checklist
- Receive microchip certificate from vet (keep a copy)
- Register with your state's official pet registry within required timeframe
- Register with your local council (separate from state registry)
- Confirm your address, phone number, and email are correct
- Update details immediately when you move or change phone number
- Check registration annually — registries sometimes have data issues
- Ensure your vet has your current microchip number on file
If Your Dog Goes Missing
Do this immediately
Contact your local council ranger
Council rangers are legally required to scan all impounded dogs. Report your dog missing with the microchip number so they can match it immediately if your dog is brought in.
Alert all local vets and shelters
Call every vet clinic and RSPCA in your area with your dog's microchip number and description. Samaritans who find dogs often take them straight to a vet for scanning.
Report to the national register
Log into your state registry and mark your dog as missing. Some national platforms like PetSearch.com.au aggregate reports across all shelters. Post on local Facebook lost pets groups with the microchip number visible.
Can Microchips Move or Fail?
Chip migration is rare but real. The chip can move from the implant site — usually remaining in the loose scruff tissue but occasionally drifting further. This is why vets scan the entire body, not just the shoulder blades. Ask your vet to scan for the chip at your dog's annual check to confirm it's still reading correctly.
Request a chip scan at every annual vet visit
A quick scan at each annual check confirms the chip is still in place and reading correctly. If your vet isn't scanning routinely, ask them to. Takes five seconds and confirms your dog's ID is intact.
