Used fish tanks in Australia typically sell for A$38 to A$285 (about $27 to $200). An empty tank is bought on volume, dimensions and the state of the silicone — it is a simpler sale than a full setup, and it lives or dies on whether the seals are sound.

Selling a fish tank in Australia
Bank transfer via PayID is instant and is what most private buyers will offer. Cash on collection remains common for larger items.
Australia Post covers everywhere, but distance pricing is real and interstate parcels cost meaningfully more than local ones.
WishThrift has not opened Australia for trading yet, so this page is a guide rather than a live marketplace — the category becomes browsable here the moment the first Australian sellers list.
Seasons are inverted relative to the UK and North America: warm-weather items move from September, and winter gear from around May.
Working out what yours is worth
- Fill it outdoors and leave it standing to test for leaks
- Confirm the filter, heater and light work
Getting it ready
- Inspect the internal silicone for lifting, discolouration or gaps at the corners.
- Clean off limescale tide marks with an aquarium-safe method, and check the glass for scratches by feel as well as sight.
Photograph
- The empty tank straight on, on a plain surface, in good light
- The base and edges, showing chips or scratches
- The lid, hood or brace bars if included, plus any damage
Put in the description
- Volume in litres and exact external dimensions
- Glass thickness if known, and whether it is braced or rimless
- Age of the tank and whether the seals have been water tested
Volume and dimensions: “120L Glass Fish Tank, 100x40x40cm, Empty”. Say empty or bare in the title so buyers do not arrive expecting equipment — if yours includes filter and heater, it is a setup and belongs in the aquarium guide instead.
Steady year round with an autumn and January lift. Standard sizes sell within a couple of weeks; very large tanks are slower because few buyers have the floor for them.
It costs nothing to list
There is no listing fee, no selling fee and no commission, so the A$287 a buyer pays is the A$287 you keep. You and the buyer settle up and arrange the handover between yourselves; WishThrift does not hold the money or ship the item.

Common questions
Where can I sell a fish tank in Australia?
List it free on WishThrift and deal with the buyer direct. There is no selling fee, so the whole amount stays with you. Bank transfer via PayID is instant and is what most private buyers will offer. Cash on collection remains common for larger items.
Have you tested it for leaks?
Fill it, wait, and report what happened. An untested old tank is worth far less than a tested one because the buyer is carrying all the risk.
What is the most common tank fault?
Perished or lifted silicone seals. Run a fingernail along the seams — any lifting means it needs resealing.
Do complete setups sell better?
Much better, because a beginner needs everything at once and a complete tank saves them sourcing each part.
