What is a sub-limit in pet insurance?

A sub-limit is a per-condition or per-treatment cap on how much your insurer will pay out for a specific category of claim, sitting inside the headline annual benefit limit. Common sub-limits include dental ($1,000–$2,500/year typical), behavioural ($500–$1,500/year), and per-leg cruciate ligament caps ($2,500–$5,000 lifetime per leg).

Where do I find sub-limits in the PDS?

Sub-limits live in the PDS Sub-limit Schedule, usually a table near the back of the document or in a Schedule of Benefits section. They aren't usually shown on the brand's marketing pages or quote summaries. Look for tables headed 'Sub-limits', 'Schedule of Benefits', or 'Per-condition limits'.

Why are sub-limits important?

The headline annual benefit limit (e.g. $25,000) is the maximum across all claims. Sub-limits cap individual condition categories inside that figure. A $25,000 policy with a $1,500 dental sub-limit gives you only $1,500 of dental cover regardless of how much annual benefit is left. Sub-limits often determine whether the policy is fit-for-purpose for your pet's likely claim profile.

Sub-limits in the pet insurance PDS.

A sub-limit is a per-condition or per-treatment cap on how much your insurer will pay out for a specific category of claim, sitting inside the headline annual benefit limit. Sub-limits don't usually appear on marketing pages — they live in the PDS Sub-limit Schedule near the back. Knowing the sub-limits matters because the headline cover number is misleading without them. A $25,000 annual cover policy with a $1,500 dental sub-limit gives you exactly $1,500 of dental cover, no matter how much general benefit is left.

What sub-limits do

The headline annual benefit limit on a pet insurance policy ($15k, $20k, $25k, $35k, $40k, depending on tier and brand) is the maximum total payout across all claims combined in a policy year. Sub-limits cap individual condition or treatment categories inside that figure. A claim eligible under a sub-limited category is reimbursed up to the sub-limit, not up to the annual benefit.

Worked example · $25,000 annual cover with $1,500 dental sub-limit

Headline annual cover$25,000

Dental sub-limit$1,500

Your pet has a $3,200 dental procedureclaim made

Insurer applies the sub-limit cap firstcapped at $1,500

Then applies excess + reimbursement %($1,500 − excess) × R%

Real payout (assuming $200 excess + 80% reimbursement)$1,040

The remaining $23,500 of annual benefit doesn't help on the dental claim — it's available for non-dental conditions. The dental sub-limit caps the dental payout at $1,500 regardless of what the annual benefit ceiling looks like. Buyers reading marketing copy that emphasises "$25,000 annual cover" can be surprised when the dental claim payout doesn't approach that figure.

The most common sub-limits to watch

Sub-limits vary brand by brand and tier by tier. The categories most commonly sub-limited in Australian pet insurance:

Dental sub-limits

Where dental cover is included in the policy (either core or add-on), it's almost always sub-limited. Typical dental sub-limits sit in the $1,000–$2,500/year range across the Australian market. PetsOnMe Deluxe sits at $500/year (the lowest in our directory). Some brands cap individual dental procedures separately from the annual sub-limit. A $5,000 oral surgery for a senior cat with periodontal disease can quickly exceed even the higher sub-limit ceilings, leaving meaningful out-of-pocket cost regardless of headline cover.

Behavioural sub-limits

Where behavioural cover is included (it's often add-on or excluded entirely — see our brand reviews), the sub-limit is typically $500–$1,500/year. Behavioural therapy under veterinary supervision can run $200–$400 per session, so a $1,500 sub-limit covers roughly 4–7 sessions in a year. Useful for short-course treatment; insufficient for ongoing chronic behavioural conditions.

Cruciate ligament and orthopaedic sub-limits

Cruciate disease in dogs is common (especially in larger breeds) and expensive (TPLO surgery typically $4,000–$7,000 per leg). Some brands apply a per-leg lifetime sub-limit on cruciate treatment ($2,500–$5,000 typical) that caps cumulative cruciate spend on each leg over the policy life. Combined with the bilateral condition rule (a pre-existing cruciate on one side excludes the other side), cruciate sub-limits are one of the most consequential cover restrictions for medium and large breed dogs.

Alternative therapy sub-limits

Where alternative therapies (acupuncture, hydrotherapy, physiotherapy) are covered, sub-limits typically apply per session and per year. The annual cap is often $500–$1,500. These therapies are most often used for chronic joint pain in older dogs and for post-surgical rehabilitation; the sub-limit is typically high enough for moderate use, restrictive for ongoing weekly therapy.

Tick paralysis sub-limits

A small number of brands apply specific sub-limits to tick paralysis treatment, which is a high-cost emergency presentation common in Eastern Australia (typical treatment $2,000–$5,000 for severe cases requiring intensive care). Where present, the sub-limit is usually $500–$1,000 per episode. Worth checking if you live in a tick paralysis zone.

Cancer treatment sub-limits

Less common but worth checking — some legacy products and lower-tier policies cap chemotherapy or oncology spend at a separate sub-limit even where the headline cover is high. Cancer treatment for dogs and cats can run $5,000–$15,000+ over a 6–12 month course; a separate cancer sub-limit can dramatically reduce real cover.

Where to find sub-limits in the PDS

Sub-limits don't usually appear on a brand's quote summary or marketing page. They live in the PDS, typically:

The Sub-limit Schedule — usually a table near the back of the PDS or in a separate Schedule of Benefits document referenced from the main PDS
The Cover Sections — individual cover sections (Section 4 dental, Section 5 behavioural, etc.) often list applicable sub-limits inline with the cover description
The Important Information section — restrictions and limits sometimes summarised here in plain language
The Certificate of Insurance — your specific policy document confirms which sub-limits apply to your tier and selected options

If you can't find a clear sub-limit table in the PDS, that's itself information — some brands fold sub-limits into the body of the cover sections rather than presenting them as a single schedule. Read the cover sections carefully for any "$X cap", "$X per year", or "$X lifetime" qualifying language attached to specific condition categories.

The buyer test. Before committing to a brand, ask yourself: what specific conditions does my pet's breed, age, or known history make most likely? Then check that brand's sub-limits for those condition categories. A high-headline-cover policy with low sub-limits in the categories you're most likely to claim is structurally less coverage than a lower-headline-cover policy with no sub-limits in those categories. Headline cover is the wrong primary filter; condition-specific sub-limits are usually the right one.

Why sub-limits exist

Sub-limits are how insurers control claims-cost concentration in known high-frequency or high-cost categories. Dental, behavioural, alternative therapy, and orthopaedic claims are predictable, repeatable cost centres — applying a sub-limit lets the insurer offer a high headline annual benefit (which sounds good in marketing) while limiting real exposure on the categories most likely to drive claims.

This isn't a moral failing on the insurers' part — sub-limits are how reimbursement insurance broadly works. The problem is the asymmetry between how prominently headline annual benefit appears in marketing (front and centre) and how prominently sub-limits appear in the same materials (rarely, and usually buried). The fix isn't to demand brands change the disclosure — it's to read the PDS Sub-limit Schedule before signing up, and to weight the sub-limits more heavily than the headline cover when comparing brands.

Why we don't tabulate exact sub-limits in our brand reviews

Sub-limits change between PDS revisions. A brand can move a dental sub-limit from $1,500 to $2,000 (or vice versa) between the 2025 PDS and the 2026 PDS without major announcement. Our brand reviews and comparison pages flag the existence of sub-limits and note where to find them ("per PDS sub-limit schedule") rather than tabulating exact figures that may be wrong by the time you buy.

The exception is where a sub-limit is unusually low or unusually high enough to be the editorially significant point — PetsOnMe's $500/year dental sub-limit on Deluxe, for example, is low enough that we call it out by figure on the PetsOnMe review and the dental comparison page. For mainstream-range sub-limits, the right way to check is to read the brand's current PDS yourself before signing up.
