Used fish tanks in Sydney 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 Sydney
Sydney is Australia’s largest city and its most expensive to live in, which pushes people into smaller flats and shorter tenancies than the house-and-garden stereotype suggests. That makes furniture that fits a small apartment, and anything to do with the harbour and the beaches, the two things that move most reliably.
Rental turnover in the inner suburbs is high and leases commonly run six or twelve months, so households here reshuffle far more often than owner-occupied ones. Summer is when the water gear changes hands and winter is when it sits unsold.
Confirm access and parking before agreeing to collect anything large. Between the terraces, the apartment blocks and the permit zones, where a vehicle can actually stop is the thing that decides most furniture sales here.
Sydney has around 5.3 million people in New South Wales, which means a buyer pool big enough that almost anything finds someone, and close enough together that collection is rarely the obstacle. Newcastle, Wollongong and Albury are close enough that a buyer there may well make the trip for the right thing.
Handing it over in Sydney
Bank transfer via PayID is instant and is what most private buyers will offer. Cash on collection remains common for larger items.

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.
Listing is free and there is no selling fee, so the whole amount the buyer pays stays with you. You and the buyer agree the handover between yourselves.

Common questions
Where can I sell a fish tank in Sydney?
List it free on WishThrift and deal with the buyer direct. The city sprawls a long way and traffic between the inner suburbs and the outer ones is the real cost of a collection, so most people arrange to meet near a train station on their own side of the city rather than crossing it. Parking near the harbour is scarce and expensive.
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.
How much is a fish tank worth in Sydney?
Most used fish tanks change hands for A$38 to A$285 (about $27 to $200). Condition and completeness move that figure more than anything else.
