Which Australian pet insurers cover pre-existing conditions? Compare policies, waiting periods, and exclusions. Complete guide to getting cover for pets with health issues.
Last Updated: March 10, 2026
When your beloved pet already has a health condition, finding insurance can feel like an uphill battle. You’re not alone — thousands of Australian pet owners face this exact situation every year. Most Australian pet insurers exclude pre-existing conditions entirely, but there are some options and important nuances you need to know before you give up.
Key Takeaway: While no Australian insurer covers pre-existing conditions that have already been diagnosed and treated, some offer coverage for chronic conditions if you switch providers during a symptom-free period, accident-only policies still provide valuable protection, and wellness plans can help manage ongoing costs. Understanding how insurers define and investigate pre-existing conditions can make the difference between a successful claim and a denied one.

What Counts as a Pre-Existing Condition?
A pre-existing condition is any injury, illness, or symptoms that occurred before your pet insurance policy starts or during the waiting period. The definition is broader than most people expect, and it’s one of the most common reasons claims get denied in Australia.
Obvious Pre-Existing Conditions
- Already diagnosed illnesses: Diabetes, arthritis, heart disease, cancer, hypothyroidism, Cushing’s disease
- Previous injuries: Cruciate ligament tears, hip dysplasia, fractures, torn ACLs
- Ongoing treatments: Any condition currently being treated by a vet, including long-term medication
- Chronic conditions: Skin allergies, epilepsy, kidney disease, inflammatory bowel disease
- Previous surgeries: If your pet had a lump removed, any recurrence or related issue is typically excluded
Gray Areas That Catch People Out
- Symptoms without diagnosis: If your vet noted limping, coughing, excessive scratching, or skin irritation — even in passing — insurers may treat the underlying cause as pre-existing, even if it was never formally diagnosed
- Breed-specific conditions: Hip dysplasia in German Shepherds and Labradors, BOAS in French Bulldogs and Pugs — if any symptoms have been noted in vet records, these can be excluded
- Age-related changes: Early arthritis signs in senior pets, dental disease, lumps noted during routine exams
- Routine findings: A heart murmur detected during a vaccination visit, elevated liver enzymes on a blood test, or dental disease found during check-ups — even if your vet said “let’s just monitor it”
- Bilateral conditions: If your dog has had a cruciate ligament tear in one knee, most insurers will also exclude the other knee, as the condition is considered bilateral
- Related conditions: Obesity noted in vet records can lead to exclusions for diabetes, joint problems, and heart disease — conditions that insurers consider related
The 18-Month Review Period
Here’s something many pet owners don’t know: some Australian insurers use an 18-month review period for pre-existing conditions. This means that if your pet had a condition that has been completely symptom-free and treatment-free for 18 consecutive months, the insurer may reconsider the exclusion.
This isn’t universal, and it’s not automatic. You typically need to:
- Request the review in writing
- Provide complete vet records covering the 18-month period
- Have your vet confirm that no symptoms, treatment, or medication occurred during that time
- Accept that the insurer has final discretion — they can still say no
Important: Australian insurers typically review your pet’s full veterinary history when you make your first claim, not when you sign up. That casual vet visit where the vet noted “mild limp, monitor” could come back to haunt you months later. This is why it’s so important to understand what’s in your pet’s records.
Your Options When Your Pet Has Health Issues
Having a pet with a pre-existing condition doesn’t mean insurance is pointless. Here are your three main options:
1. Accident-Only Coverage
Even pets with significant chronic illnesses can still benefit from accident coverage. Accidents are unpredictable and can be devastatingly expensive — a snake bite antivenin alone can cost $3,000-$10,000 in Australia.
- Covers: Car accidents, snake bites, tick paralysis treatment, toxic ingestions (baiting, poisonous plants), fractures from falls, lacerations, foreign body ingestion (socks, toys, bones), dog attack injuries
- Doesn’t cover: Illness, disease, or anything related to existing conditions
- Cost: Usually 50-70% cheaper than comprehensive cover — often $15-35/month
- Best for: Pets with manageable chronic conditions who need protection from unexpected accidents
Accident-only cover is particularly worth considering for active dogs who spend time outdoors, dogs in snake-prone areas (most of regional Australia), and breeds prone to foreign body ingestion like Labradors and Golden Retrievers.
Tip: Some accident-only policies also cover emergency boarding fees if you’re hospitalised and can’t care for your pet. Check the PDS for these extras.
2. The “Chronic Condition Switch”
Some insurers may cover chronic conditions if you can prove your pet has been symptom-free for an extended period. This is sometimes called “portability” or “condition review.”
Fetch Pet’s Approach:
- 6+ months symptom-free with vet documentation
- Condition must be well-controlled or fully resolved
- Coverage decision made on individual basis by their underwriting team
- Not guaranteed, but worth trying — they’re currently the most flexible major insurer
PetsOnMe’s Approach:
- Assessed case by case — no blanket policy
- Generally requires longer symptom-free periods than Fetch
- May apply a higher excess or sub-limit to previously excluded conditions
What you’ll need for either insurer:
- Complete vet records showing the symptom-free period (every visit, not just relevant ones)
- Letter from your current vet confirming the condition is stable or resolved
- Proof of any ongoing management (medication, prescription diet)
- Patience — underwriting reviews can take 2-4 weeks
3. Wellness Plans and Preventive Care Cover
While not traditional insurance, wellness plans can help offset the ongoing costs of managing a pre-existing condition. Several Australian providers now offer these as standalone products or add-ons:
- What they cover: Routine vet consultations, vaccinations, dental cleans, parasite prevention, prescription diets, and sometimes ongoing medication
- What they don’t cover: Emergency treatment, surgery, hospitalisation
- Cost: Typically $30-60/month, with annual benefits of $400-800
- Best for: Pets with stable chronic conditions that require regular vet visits and ongoing medication
A wellness plan paired with accident-only insurance can provide surprisingly comprehensive protection for a pet with pre-existing conditions — often for less than a full comprehensive policy would cost for a healthy pet.
How Insurers Investigate Pre-Existing Conditions
Understanding the claims investigation process helps you avoid surprises and prepare your documentation properly.
When the Investigation Happens
Most Australian pet insurers do not request your vet records when you first take out a policy. Instead, they review your pet’s history when you submit your first claim — or sometimes when you submit a claim for a significant amount. This means you might pay premiums for months before discovering that a condition is excluded.
What Insurers Request
When investigating a claim, your insurer will typically:
- Request complete vet records — from every vet your pet has visited, not just the treating vet. They’ll ask you to sign an authority form allowing them to contact any veterinary practice.
- Review clinical notes in detail — insurers have veterinary consultants who read through every line of your pet’s history, including notes you may never have seen yourself.
- Look for related symptoms — a claim for a knee injury might be denied if your vet noted “slight limp on right hind” during a vaccination visit two years ago.
- Check timing against your policy start date and waiting periods — any symptom or sign that falls before coverage began, or during the waiting period, can trigger an exclusion.
Common Investigation Outcomes
- Claim approved: No evidence of pre-existing symptoms or conditions found
- Claim denied: Evidence found that the condition, or related symptoms, existed before coverage
- Partial exclusion applied: The specific condition is excluded going forward, but your policy otherwise remains intact
- Policy-wide exclusion: In some cases, a broader exclusion is applied (e.g., “all orthopaedic conditions” rather than just “left knee”)
Dispute Resolution
If your claim is denied and you believe the decision is wrong, you have several options:
- Internal review: Ask the insurer to review the decision. Provide any additional vet records or letters that support your case.
- Request the specific reason: Insurers must tell you exactly why a claim was denied and which vet records they relied on. Ask for this in writing.
- Get your vet involved: Your vet can write a letter explaining why, in their clinical opinion, the claimed condition is not related to any prior issue.
- Escalate to AFCA: If the internal dispute process doesn’t resolve things, you can lodge a complaint with the Australian Financial Complaints Authority (see below).
Your Rights: Australian Consumer Protections
Pet insurance in Australia is regulated as a general insurance product. This means you have real protections, regardless of which state or territory you live in.
The Insurance Code of Practice
All major Australian pet insurers subscribe to the General Insurance Code of Practice, which requires them to:
- Handle claims promptly and fairly
- Provide clear reasons for claim denials in writing
- Offer an internal dispute resolution (IDR) process
- Inform you of your right to escalate to an external body
- Not use unfair contract terms (regulated under Australian Consumer Law)
Australian Financial Complaints Authority (AFCA)
AFCA is the free, independent external dispute resolution scheme for financial services, including pet insurance. If you’ve exhausted your insurer’s internal complaints process and you’re still not satisfied:
- Cost: Free for consumers
- Time limit: You generally have two years from the insurer’s final response to lodge a complaint
- Process: AFCA will review all evidence from both sides and make a binding determination
- Website: afca.org.au
AFCA has handled an increasing number of pet insurance disputes in recent years, and their determinations are publicly available — which means insurers are motivated to resolve complaints before they reach this stage.
What This Means for Pre-Existing Condition Disputes
If you believe your insurer has unfairly classified a condition as pre-existing, you have a genuine path to challenge the decision. Key things that strengthen your case:
- A vet letter clearly distinguishing the new condition from any prior symptoms
- Evidence that the earlier symptoms were investigated and ruled out as a different issue
- Proof that the insurer’s definition of “pre-existing” is being applied unreasonably broadly
- Any inconsistency between the insurer’s PDS wording and how they’ve applied it
Frequently Asked Questions
Q: Can I get insurance for my pet that already has arthritis?
A: You can get accident-only coverage, but the arthritis and any related conditions (joint issues, mobility problems, lameness) will be permanently excluded. Consider pairing accident-only cover with a wellness plan for ongoing arthritis management, including prescription anti-inflammatory medication and joint supplements.
Q: Will insurers cover my diabetic cat for other illnesses?
A: Most will exclude diabetes and any conditions insurers consider related (which may include obesity, urinary tract issues, pancreatitis, and kidney disease). However, unrelated illnesses like cancer, respiratory infections, or accidents should still be covered. Check with individual insurers, as the scope of “related conditions” varies significantly.
Q: If my pet has been symptom-free for 2 years, will they be covered?
A: Possibly. Fetch Pet considers chronic condition switches after 6+ months symptom-free, and some insurers have an 18-month review process. You’ll need full vet documentation proving the symptom-free period. It’s not guaranteed, but a two-year symptom-free period gives you the strongest possible case.
Q: Do insurers check vet records when I sign up or when I claim?
A: Almost always when you claim. Most insurers accept applications without vet checks, then review your pet’s full veterinary history when you lodge your first significant claim. This is why it’s crucial to understand what’s in your pet’s records before you need to claim.
Q: Can a breed predisposition be treated as a pre-existing condition?
A: A breed predisposition alone is not a pre-existing condition. However, if your vet has noted any symptoms — even mild ones — related to a breed-specific condition, insurers can exclude it. For example, a French Bulldog with no breathing symptoms noted in their records shouldn’t have BOAS excluded, but one where the vet wrote “mild stertor noted” could.
Q: What if I change vets — will the new insurer know about my old vet records?
A: When you make a claim, insurers will ask you to authorise access to records from all veterinary practices your pet has attended. Failing to disclose a previous vet, or providing incomplete information, can result in your entire policy being voided. It’s always better to be upfront.
Q: Is it worth getting pet insurance if my pet already has multiple conditions?
A: It depends on the conditions. If your pet has several chronic illnesses, comprehensive cover may exclude so much that it’s not good value. However, accident-only cover (typically $15-35/month) can still save you thousands if your pet is hit by a car, bitten by a snake, or ingests something toxic. Run the numbers for your situation.
Q: Can I dispute a pre-existing condition exclusion?
A: Yes. Start with the insurer’s internal dispute process, get a supporting letter from your vet, and if necessary escalate to AFCA (the Australian Financial Complaints Authority). Disputes are most successful when you can show the insurer has applied the exclusion more broadly than their PDS wording supports.
Next Steps
If Your Pet Has Pre-Existing Conditions:
- Request your pet’s complete vet records — before you even apply for insurance, know exactly what’s in there. You’re entitled to a copy under Australian privacy law. Read through them carefully and note anything an insurer might flag.
- Get quotes for accident-only coverage from Fetch, PetsOnMe, and Bow Wow Meow — compare what’s included (tick paralysis, snake bite, foreign body) and the excess amounts.
- Consider pairing accident-only cover with a wellness plan — this combination can cover both unexpected emergencies and the day-to-day costs of managing a chronic condition.
- Document any symptom-free periods — if your pet’s condition has resolved or is well-controlled, keep a log and ensure your vet records reflect this at every visit. Ask your vet to note “no signs of [condition]” during routine check-ups.
- Build a dedicated emergency fund — set aside $50-100/month in a separate savings account for excluded conditions. Even $1,200/year can make a significant difference when an unexpected flare-up occurs.
- Talk to your vet — they deal with insurance companies regularly and can advise on how to document your pet’s health in a way that’s accurate but doesn’t inadvertently trigger exclusions.
- Don’t give up — if one insurer excludes a condition, try another. Underwriting criteria vary, and a condition one insurer excludes broadly may be treated more narrowly by another.
If Your Pet Is Still Healthy:
- Get comprehensive coverage now — don’t wait for problems to develop. Every day without insurance is a day where an illness or injury could become a permanent exclusion.
- Consider higher coverage limits while your pet is young and healthy — premiums are lowest when your pet has a clean bill of health.
- Keep vet records clean — attend regular check-ups so your vet has a documented history of good health. This makes future claims much smoother.
- Understand your waiting periods — most policies have a 30-day waiting period for illness and a 2-day period for accidents. Any condition that appears during the waiting period will be treated as pre-existing.
