Storage Box Index · September 2026

What a standard storage unit costs in Australia

One unit, one measure, every month: the median standard (ongoing) price of a standard 9 m² self-storage unit — about the size of a single garage.

$275per month

National median standard rate, net of GST, September 2026 — the ongoing price after any introductory period. The promo-inclusive advertised median is $230. -1.0% on last month, measured across the same units. Based on 1,671 units.

Apr $293 Sep $275
Like-for-like price change over the last 6 months — a matched panel (the same units month to month, standard rate), rebased to today's $/mo, so provider and promotion mix are held out. Down $18 a month (6.1%) since Apr. The raw advertised median moved -17.3% over the same window; the gap is provider/promotion mix, not price.

By capital city

The parity column indexes each city against the national median (= 100). Sydney at 144 means a standard box costs 44% more there than the national middle.

Brisbane $278 101 -0.5% 192
Melbourne $275 100 +0.4% 271
Adelaide $273 99 +0.0% 52
Perth $270 98 +0.4% 132

The advertised price is often a promotion

About 35% of advertised units carry a promotion. Among the listings that also show an original price, the median discount is 50%.

Not every operator publishes an original price, so the discount figure describes the listings that do. Promotional rates are usually introductory: check the ongoing rate before you sign.

Method

The Storage Box Index headline is the median standard (post-introductory) monthly price of a 9 m² unit, net of GST: each current listing's ongoing rate is divided by its floor area and scaled to 9 m², then medianed across the providers we track. It is computed live from the same data as our API and AI tools, so every surface publishes the same number, and the advertised (promo-inclusive) median is reported alongside. The national figure pools every capital-city market. Month-on-month change uses a matched panel on the advertised series: the same units priced in both months, so a change reflects a real price move rather than a shift in which facilities we happened to measure. A city is published only once it clears a minimum sample, so thin months are withheld rather than estimated.

Prices are advertised public rates, GST-inclusive: a snapshot of what operators choose to advertise, not a guarantee of availability or of the final price you are quoted. A promotional rate is not the rate you pay once the promotion ends. Data confidence: high. Updated September 2026.
