Fish Tank Setup Cost in Australia 2026, and Where It Is Cheapest

Published: 8 October 2026 · Author: Mirabelle Chew, Fashion Editor, ShopBack

Short answer. In Australia in 2026, a basic fish tank setup costs about $93 to $155 for an all-in-one beginner kit and about $429 to $749 for a starter kit with stand, heater and lighting, based on Petbarn's regular prices at the time of writing. It is usually cheapest to buy a complete kit during a member sale at Petbarn or Petstock, and to check ShopBack before you check out.

New to ShopBack? ShopBack Australia is a free app and website that gives you cash back when you shop through it at stores like Petbarn and Petstock. You open the store from ShopBack, buy as normal, and part of what you paid comes back to your ShopBack account to withdraw. Join ShopBack Australia free before you buy your tank.

How we checked. We used Petbarn's own product listings for aquarium kits, heaters and water care, Petbarn's Friends for Life loyalty page, and the terms on each store's ShopBack page, in October 2026. Prices quoted are Petbarn's listed regular prices on the day we checked; member sale prices were often lower and all prices change.

Average fish tank aquarium cost: starter kit prices

A starter kit is the cheapest way into fishkeeping, because the tank, filter and basics are priced together. Here is what Petbarn listed for its aquarium range at the time of writing (regular non-member prices; member sale prices are often lower, and all prices change):

Kit	Size	Petbarn regular price at the time of writing
Aqua One Exclusive Goldfish Aquarium Learner Kit	21L	$93
Aqua One Exclusive Tropical Aquarium Learner Kit	28L	$155
Fluval Curve Aquarium	32L	$279
Aqua One Focus Aquarium	36L	$203
Fluval Curve Aquarium	60L	$349
Aqua One Horizon 65 Glass Starter Kit with stand	65L	$429
Aqua One Horizon 130 Glass Starter Kit with stand	130L	$599
Aqua One Horizon 182 Glass Starter Kit with stand	182L	$749
Aqua One Grandview Aquarium Kit	240L	$1,299

What that means for a typical budget:

• Kids' first goldfish tank: about $93 regular for the 21L learner kit, which Petbarn lists as including the tank, lid, filter, flake food, water conditioner, bio starter, gravel, an ornament and a background. Add the fish.
• Small tropical tank: about $155 regular for the 28L tropical learner kit, which Petbarn lists as also including a glass heater.
• Living room tank with stand: about $429 to $749 regular for the Horizon range, which Petbarn says includes a hang on filter, heater, lighting and a stand. Gravel is not included.
• Large display tank: from about $1,299 regular for a 240L kit, before decor, plants and fish.

How much does a fish tank setup cost in Australia, and where is it cheapest?

Based on Petbarn's listings, most first fish tank setups in Australia come to roughly $100 to $500 all in, and they are usually cheapest when bought as a complete kit during a member sale. The tank is only part of the bill. Use this checklist to price the full setup:

Item	Needed for	Petbarn price seen (regular)
Tank or kit	Everyone	$93 to $1,299 depending on size
Heater	Tropical fish	Aqua One glass heaters $51 (25W) to $75.50 (300W)
Thermometer	Tropical fish	$7.50
Water conditioner	Everyone, every water change	API Tap Water Conditioner from $16.99 (118ml)
Water test kit	Everyone	Tetra EasyStrips 6-in-1 $26.50 (25 tests); API 5 in 1 Master Test Kit $97.99
Gravel, plants and decor	Most tanks	Varies
Fish	Everyone	Varies by species and store

Where it is usually cheapest:

1. Buy a complete kit, not separate parts. A learner kit that already includes the filter, heater and water care usually costs less than buying each part on its own.
2. Join the store's free loyalty programme before you buy. Petbarn shows member sale prices on selected aquarium kits, and these can sit well below the regular price.
3. Compare the same tank at two stores. Same brand, same litres, same inclusions.
4. Check ShopBack before you check out. It lowers the effective price of the order after you pay.

Fish tanks in Australia: the main types

Fish tanks sold in Australia mostly fall into three groups: small learner kits, desktop or curved tanks, and larger tanks sold with a stand.

• Learner kits (about 20L to 30L). Built for beginners and kids, with most of the essentials in the box.
• Desktop and curved tanks (about 30L to 60L). Fluval Curve and Aqua One Focus are examples. These suit a bench or bookshelf and usually need you to choose fish carefully because of the smaller water volume.
• Tanks with stands (65L and up). The Aqua One Horizon range pairs the tank with a stand that has two shelves, according to Petbarn. A bigger tank holds more stable water, which many keepers find easier to look after, but it costs more to set up and run.

Size check before you buy: Petbarn lists the Horizon 65 tank at 36cm high, 60cm wide and 30cm deep, with the stand at 61cm high. Measure the space and check the floor can take the weight of a full tank.

Fish tank Australia 2026: what to know before you buy

In 2026 the things that change what you pay are the tank size, whether you keep tropical or cold water fish, and when you buy.

• Tropical or cold water. Tropical fish usually need a heater and thermometer; goldfish usually do not.
• Member pricing changes often. Petbarn's member sale prices on aquarium kits come and go, so check the listing on the day you buy.
• Returns. Petbarn's listings describe free returns on eligible products within a set window; check the store's returns policy for live animals and opened items before you buy.
• Delivery. Petbarn offers home delivery and click and collect; check the delivery options and any free delivery threshold for your postcode at checkout, since large tanks can be heavy.

Fish tank best deals in Australia for 2026

The best fish tank deal is the lowest total for the full setup you need, not the lowest tank price. A cheap tank that needs a separate filter, heater and lighting can end up costing more than a kit.

• Use the store's own programme. Petbarn's Friends for Life members earn 10, 12 or 14 points per $1 depending on their tier (Silver up to $550 yearly spend, Gold $550 to $1,100, Platinum over $1,100), and 6,000 points become a $10 voucher, according to Petbarn. Petstock runs its own free loyalty programme, Petstock Rewards.
• Look for price promises. Petbarn advertises "Found it cheaper? We'll match it" on its site; read its terms for which products and competitors qualify.
• Time the purchase. Member sales rotate, so if the kit you want is at the regular price, it may be worth checking back.
• Open the store from ShopBack. Before you check out, go through ShopBack to get a post-purchase discount on the order, covering eligible items in the same cart under the store's terms.

Check ShopBack before you check out

Make ShopBack the step before payment. Nothing about the order changes. You still buy on Petbarn or Petstock, you just start on ShopBack Australia.

1. Open the ShopBack app or website and sign in.
2. Tap Petbarn or Petstock.
3. Add your tank and supplies to the cart and check out in that same session.
4. Once the order is confirmed, the cash shows in your ShopBack account and you can withdraw it.

Before you check out, go through ShopBack to get a post-purchase discount on the order. Cashback lowers what you actually pay for an order. It comes back as cash, so it works like a discount on the price, not like points or miles.

Illustrative example: a 65L starter kit with stand costs $429. At an illustrative 5% rate, $21.45 comes back to your ShopBack account, so the effective price is $407.55. Real rates differ by store and change often, and some products may be excluded, so check the live rate and terms on the store's ShopBack page before you buy.

To make sure it tracks:

• Check out in the same session you opened from ShopBack.
• Read the store's terms on its ShopBack page, since some products or services may not qualify.
• Check before you use a promo code. Some stores only pay on orders that use codes listed on their ShopBack page.
