Fish & Koi Cremation in Australia: what to know
Rules in Australia tend to say more about the fish still alive than the one that died. Releasing unwanted pet fish into rivers, lakes or ponds is restricted in many countries because it spreads disease and harms native species. For a fish that has died, cremation needs no permit, and burial on private land is allowed in many countries, though not all. The details for Australia are below.
Across Australia, the weather shapes fish aftercare as much as the rules do. Hot spells cause pond oxygen crashes and speed up decay, so prompt action matters; cold winters freeze ponds and ground, so many families keep a fish in the freezer until spring. Both situations are covered on the city pages below.
We cover 29 communities in Australia, from Sydney, Melbourne and Brisbane to smaller towns.

How we calculated this
The sum of our per-city estimates for the 29 communities in Australia on this site: each city's population ÷ national average household size × the national share of households with a fish. Households with several pets count once.

Cremation in Australia: a little context
Urns and keepsakes are easy to buy in Australia, where cremation is the choice for about 71%[1] of people, but most are sized for a cat or a dog, and a fish's ashes can look lost inside them. Look for a keepsake urn of a few cubic inches, a glass heart or a small wooden box. The urn size calculator helps if you're unsure. For a large koi, one small urn indoors and a pinch saved for the garden often works well.
We take the Australia percentage from FuneralSmart (2023). It refers to people; attitudes to cremating a pet tend to follow it.
Why a small fish still has a minimum price
Not every cost appears on a price list. Losing a fish you'd kept for years can hit harder than friends expect, and support is available without charge: Griefline covers pet loss, and a 24/7 pet loss line run by Pets and People costs nothing to ring from either country[2]. In Australia, spending on a cremation is a choice; talking to someone afterwards can be just as useful and costs nothing.
Prices in Australia follow the provider's smallest-pet rate. In New Zealand, one Auckland crematorium lists NZD 305 for individual and NZD 55 for communal cremation of a 2 to 7 kg pet[3], a useful benchmark for a fish. In Australia, RSPCA Queensland's memorial packages start from AUD 250; within 14 days[4]. Ask for the price in writing before you agree.
| Service | Price | Notes |
|---|---|---|
| Australia, individual, up to 5 kg | Median about AUD 412 | Range AUD 295 to 612 |
| Australia, communal | from AUD 80[5] | No ashes returned |
| Auckland, 2–7 kg pet | NZD 305 individual / NZD 55 communal | One provider's listed prices |

Rules worth knowing in Australia
A loss sometimes leads families to give up fish keeping altogether. If you're rehoming the fish that are left, offer them to a fish store, a club or another keeper; don't be tempted to free them in a local stream or lake, however healthy the water looks. Escaped pet fish spread parasites and compete with native species. For the fish you've lost, the local rules in Australia are below.
In Australia, koi are a form of common carp, which is a declared pest in parts of the country, and Queensland restricts keeping them at all. Goldfish and other aquarium fish should never be released into waterways. Summer heat makes the freezer essential after a fish dies, and many councils limit backyard burials in suburban areas.
The first day after a fish dies
- If a big koi is going for private cremation, take its length and get a rough weight by standing on bathroom scales holding the bagged fish.
- Photograph its markings before it goes in the freezer. A photo can be checked against the paperwork later, and many families treasure it regardless.
- Wrap it in an old towel inside two strong bags and freeze it lying flat so it fits a cooler later.
- Call a provider that has cremated fish before and ask how much ash it expects and how it tracks each pet.
- Work out the urn size using the urn size calculator first, so you don't buy the wrong one.
- Drive it over in an insulated box with frozen gel packs, and think ahead about a home for the ashes, whether that's indoors on a shelf, out in the garden or beside the pond.
Keeping your fish part of the family story
Biodegradable memorials suit a water animal. A plantable urn or a simple paper-wrapped burial under a water iris returns everything to the garden within a season or two. Our guides on biodegradable memorials and pond-side markers cover the options. In Australia, a native marginal plant at the pond's edge also feeds wildlife, which is a quiet way to let one life support others.
The services page compares what each option includes, the planning tools turn your animal's details into figures, and the poll results show what other families chose. All locations lists every region we cover.

Questions people ask
Can I bury a fish in my garden in Australia?
Usually yes, on land you own, with sensible care: wrap the fish in paper or cotton and keep well away from ponds, streams and wells. Local rules can be stricter, and landlords may object. A large planter with a new plant is a good alternative.
Can I scatter my koi's ashes in a lake or river in Australia?
It depends on who manages the water, and some public waters require permission. Scattering around your own pond, in the garden rather than into the water, avoids the question and keeps the memorial close. If you use a public place, choose a quiet spot and check the rules first.
Where can I find pet grief support in Australia?
Two places to start: Griefline, whose support covers the death of a pet, and a round-the-clock pet loss line from Pets and People with free calls on both sides of the Tasman[2]. Any counsellor they pass you to may set their own fee. Many callers are relieved just to have the loss taken seriously, and that applies to a long-lived goldfish as much as a dog.
Where can I find out why my fish died in Australia?
An aquatic vet is the best first stop, and pond clubs or aquarium shops generally know one. Some university vet schools and fish health labs also examine samples. Keep the body chilled in the fridge rather than frozen and call quickly, since ice crystals ruin the tissue a pathologist needs. Knowing the cause can protect the fish you still have.
Why do pond fish die in hot weather in Australia?
Warm water holds less oxygen, and on hot, still nights levels drop lowest around dawn. In hot parts of Australia, such as Australia where summer highs average about °F, an air pump or fountain helps, and a dead fish should be removed and frozen promptly.
Can I keep a koi's ashes outdoors by the pond in Australia?
Yes, if the container can cope with the weather. Choose a sealed, frost-proof urn in stone, metal or glazed ceramic, or place a small inner urn inside a hollow garden ornament. Ordinary wood and unglazed pottery crack in freezing weather and fade in strong sun. Set it on a firm base away from the splash zone, and consider burying most of the ashes and keeping only a little on display.
