Dog and Cat Vaccinations in Australia: What You Actually Need to Know

Vaccination is one of those topics where pet owners often know they need to do it, but aren't always sure what they're actually vaccinating against, how often it's needed, or what the difference is between a C3 and a C5.

I'm Dr Nic Cher, BVMS, and I've been vaccinating dogs and cats across Australia since 2012. I own Fortitude Valley Vet and South Brisbane Vet, and I've seen the consequences of under-vaccination — parvovirus in puppies, cat flu in kittens, kennel cough outbreaks. These are preventable diseases. Let me walk you through what you need to know.

What Does 'C' Mean in Dog Vaccination?

In Australia, dog vaccines are classified by a 'C' number, which refers to how many disease components the vaccine covers. The higher the number, the more diseases it protects against.

•       C2 (Or KC): Covers Bordetella bronchiseptica and Canine Parainfluenza

•       C3 (core vaccine): Covers Parvovirus, Distemper, and Hepatitis — the three diseases every dog in Australia should be vaccinated against

•       C5: All of the above plus Bordetella bronchiseptica and Canine Parainfluenza — the two main kennel cough pathogens

The C3 is the minimum recommended vaccination for all dogs in Australia, regardless of lifestyle. The C5 is required (or strongly recommended) for dogs that go to kennels, doggy daycare, dog parks, or come into regular contact with other dogs.

What Does 'F' Mean in Cat Vaccination?

The same principle applies to cats. The 'F' stands for feline, and the number indicates how many components are covered.

•       F3 (core vaccine): Feline herpesvirus, Feline calicivirus, and Feline panleukopaenia

The F3 is the standard recommended vaccine for all cats in Australia. I only offer the F3 at my clinics because it covers the core diseases that every cat — indoor or outdoor — should be protected against.

There are additional feline vaccines available (FIV, FeLV), but they're not part of the core vaccination schedule and are only recommended in specific circumstances. Speak to your vet if you have questions about your cat's individual risk.

How Often Do Dogs Need to Be Vaccinated?

This is where a lot of confusion comes from, and it's worth explaining properly.

Puppies

Puppies need a primary vaccination course to build immunity from scratch:

•       6-8 weeks: First vaccination

•       10-14 weeks: Second vaccination

•       14-16 weeks: Third vaccination

•       6 months: Final puppy vaccination

Until this course is complete, your puppy's immunity is not fully established. Maternal antibodies from the mother can interfere with the early vaccines, which is why the series is needed.

Adult dogs

Adult dogs that have completed their primary course can often move to less frequent boosters. At my clinics, I use the Nobivac triannual vaccine — a product registered by the APVMA that provides three years of core (C3) protection. This means many adult dogs only need a C3 booster every three years.

However, if your dog requires C5 (kennel cough cover), the Bordetella and Parainfluenza components require annual boosting. So dogs going to boarding kennels or daycare will still need annual visits for the kennel cough portion.

How Often Do Cats Need to Be Vaccinated?

Kittens

•       6-8 weeks: First F3

•       10 weeks: Second F3

•       14 weeks: Third F3

•       6 months: Final kitten vaccination

Adult cats

After the primary course, adult cats need F3 boosters every 1-3 years depending on their lifestyle and risk profile. Your vet will advise you at each visit. Indoor-only cats with low risk may be able to go to a three-year schedule; cats with outdoor access or exposure to other cats may need more frequent boosters.

What Do Dog and Cat Vaccinations Cost in Australia?

Vaccination costs vary between clinics and cities. At my two Brisbane clinics — Fortitude Valley Vet and South Brisbane Vet we offer affordable health checks and vaccination prices.

I publish these prices (June 2026) directly because I think pet owners deserve to know what they'll pay before they book. In Brisbane, vaccination costs can vary quite significantly between clinics — particularly in inner-city suburbs — so it's worth asking upfront.

Consultation - From $89.00

Required for all vaccination appointments

Dog vaccination (C2/KC, C3 or C5) - $40.90

Vaccine cost, added to consultation

Cat vaccination (F3) - $30.90

Vaccine cost, added to consultation

Dog total (example C3)

Consultation + C3 vaccine - From $129.90

Cat total (example F3)

Consultation + F3 vaccine - From $119.90

As a general guide for other parts of Australia: expect to pay between $80-$130 for a consultation and $50 -$120 for the vaccine component, depending on your city, suburb, and clinic. Specialist or emergency clinics will charge more. Low-cost or community vet services may charge less.

Why Does Vaccination Require a Consultation?

A common question I get: 'Can't I just come in for the jab without paying for a consult?'

The short answer is no — and not just because of the fee. A vet is legally required to examine an animal before administering any prescription medicine, which includes vaccines. But beyond the legal requirement, the examination is genuinely useful.

Every vaccination appointment at my clinics includes a full physical health check. I examine the heart, lungs, teeth, skin, joints, abdomen, eyes, and ears. I've found heart murmurs, early dental disease, tumours, and weight problems at what owners thought was 'just a vaccination visit.' The consult is the most valuable part of the appointment.

Can My Indoor Cat Skip Vaccination?

I hear this often, and I understand the logic: 'She never goes outside, so what's she being exposed to?'

The reality is that cat flu viruses (herpesvirus and calicivirus) can be brought into the home on clothing, hands, and shoes, or introduced by a new cat. Feline panleukopaenia is extremely hardy and can survive in the environment for months to years. I vaccinate indoor-only cats and always will.

The risk is lower for an indoor cat than one that goes outdoors. But 'lower risk' isn't the same as 'no risk' — and the cost of vaccination is modest compared to the cost of treating an unvaccinated cat with panleukopaenia or severe cat flu.

The Nobivac Triannual Vaccine — What Is It?

I use the Nobivac triannual vaccine at both of my Brisbane clinics. It's manufactured by MSD Animal Health and is registered with the Australian Pesticides and Veterinary Medicines Authority (APVMA) for three-year core protection in dogs.

This means eligible adult dogs can have their C3 core booster every three years rather than annually. The triannual schedule doesn't apply to the kennel cough components, which still need annual boosting.

Vaccinations and Pet Longevity

Three of my own dogs lived to ages 18, 19, and 20. I've thought a lot about what gives dogs and cats the best chance at a long, healthy life — and consistent preventive care, starting with vaccination, is foundational to that.

It's not glamorous. It doesn't generate headlines. But up-to-date vaccination is one of the clearest, most evidence-backed interventions available to pet owners. Parvovirus kills unvaccinated puppies. Cat flu causes lifelong chronic illness. These aren't abstract risks — they're things I still see in clinical practice.

If your pet is overdue for a vaccination, book a visit. It's one of the highest-value things you can do for their long-term health.
