How much does a self-storage unit cost in Australia? [2026]

Whether you need moving storage between leases, mid-renovation, or just need somewhere to put the stuff you can’t quite let go of, a self-storage unit is one of the most practical options out there. But how much does a storage unit cost, and what are you actually paying for? 

In Australia, storage unit prices range from around $50 per month for a basic locker to $800 or more for a large unit. The median price for a medium-sized unit sits at around $280/month nationally, though that shifts quite a bit depending on where you are and what features you need. This guide breaks it all down.

Self-storage units are private, lockable spaces you rent to keep your belongings safe, short-term or long-term. These are helpful for people who are moving, downsizing, or undergoing a home renovation and need a temporary holding space for their things without the pressure to unpack straight away. They come in a range of sizes and types, so whether you’re storing a few boxes or the full contents of a three-bedroom home, there’s an option that fits. 

Most self-storage facilities offer flexible month-to-month terms, so you can scale up, downsize, or move out without a lot of fuss.

How much does a self-storage unit cost per month?

For a small to medium unit, you’re typically looking at $140 to $500 per month. Larger units can push past $800 per month. Self-storage costs shift based on where you are, how big the unit is, and what extras you need, like climate control or 24/7 access. More on all of that below.

How much does a self-storage unit cost per week?

Some facilities offer weekly billing at around $60 to $100 per week for a standard unit. It’s a handy option for short stretches, but most places require at least one month’s rental upfront, so even with weekly billing, you’ll often be charged for four weeks from the start.

How much is a storage unit per city

Understanding how different rental periods impact your costs can help you choose the best plan for your needs. Here’s a breakdown of typical pricing structures for short-term and long-term storage:

How much is a storage unit per city

Where you are in Australia makes a real difference to what you'll pay. Inner-city facilities in Sydney and Melbourne sit at the top end, while Adelaide and Perth tend to be noticeably more affordable. The figures below reflect the typical storage unit cost per month for a medium unit (5–10 sqm) across major cities, based on 2026 live pricing data.

It’s worth knowing that prices for the same unit size can vary 30–50% between providers in the same suburb. A facility 10–20 km outside the CBD can cost up to 40% less than one in an inner-city location, so if you don’t need frequent access, it’s worth looking a little further out.

Less clutter, more space

Tucking rarely used items into storage frees up room at home without having to get rid of things you might actually want later. It's a simple way to reclaim your garage, spare room, or office.

Downsizing made easier

Storage gives you the breathing room to keep valued possessions while you figure out what fits in your new space, without having to make snap decisions about what to keep or donate.

Better security

Most facilities offer locked units, CCTV, and on-site monitoring, so your belongings stay safe whether you're visiting daily or leaving things untouched for months.

Flexible pricing and terms

Facilities typically offer a range of storage unit sizes, prices, and contract lengths. You can start small, scale up if you need more space, and move out when you're done, without being locked into more than you need.

Protection from external elements

A decent storage unit keeps your things dry and sheltered. Go for a climate-controlled storage unit, and your items should be protected from temperature swings and humidity.

Location

Storage in major cities costs more than in outer suburbs or regional areas. Higher real estate prices flow straight through to what you're charged. If you can manage the extra travel, a facility a little further out can save you a meaningful amount each month.

Rental period

Short-term storage generally costs more per week than a longer commitment. If you're in the middle of an interstate move and need storage to bridge the gap between homes, locking in a longer agreement upfront usually works out cheaper than rolling month-to-month.

Climate control

Electronics, timber furniture, leather, artwork, and books can all deteriorate in extreme heat or humidity. Climate-controlled storage maintains a steady temperature and moisture level year-round. It costs more, but it's worth it for anything sensitive, particularly if you’re in Queensland or the Northern Territory, where summers are punishing.

Security

Basic lock-and-key facilities are the most affordable. Units with CCTV, individual alarms, and security patrols cost more but offer more peace of mind, particularly for high-value items.

Unit size

Bigger units cost more, and the jump between sizes can be significant. Going from a medium to a large unit can add $80 to $150/month, so it’s worth measuring what you're actually storing before you commit to a bigger space. A 5 x 3m unit can hold the contents of a two-to-three-bedroom home. A 3 x 3m unit suits a one-bedroom apartment's worth of boxes and furniture.

Seasonality

Demand spikes around Australia’s busiest moving periods: Christmas, January, and over the summer. If you’ve got some flexibility on timing, booking in autumn or mid-year often means better rates and more availability.

Hidden fees to watch for

The advertised rate isn’t always the full cost. Security deposits, admin fees, insurance premiums, and late payment penalties can all add to your bill. Always ask for a full cost breakdown before signing up, and ask specifically whether the first-month rate is promotional or ongoing.

The type of unit you go for is one of the bigger drivers of price. Here's what's typically on offer:

Standard units

Standard units are the most common option. These are suitable for general household items, furniture, and boxes. They're also the most affordable, typically ranging from $50 to $300 per month, depending on size and location.

Climate-controlled units

If you're storing anything sensitive to heat, cold, or moisture, climate control is worth the extra cost. Prices generally start around $150 per month for a small unit and can reach $500 or more for larger, premium spaces.

Drive-up and outdoor units

Accessible directly from the car park and ideal for vehicles, boats, caravans, or bulky gear you need to get to regularly. Expect to pay around $80 to $250 per month, depending on the size and facility.

Portable and mobile units

A portable storage unit gets delivered to your door, you fill it up, and it's taken to a facility or your next location. No need to hire a truck or make multiple trips. Prices start from around $100 to $200 per month, though delivery and pickup fees may apply on top.

Commercial units

Larger spaces designed for businesses storing inventory, documents, or equipment. Monthly rates range from $150 to $600 or more, depending on size and features. Business pricing tends to reflect longer-term contracts and bulk agreements.

Tips for choosing a storage facility

Looking for cheap storage units without compromising on security or access? A few simple steps can help you find better value without the guesswork.

• Shop around. Rates vary significantly between facilities, even in the same suburb. Get two or three quotes before committing, and compare price per square metre rather than just the headline monthly rate.

• Ask about deals. Many facilities offer first-month discounts, online booking rates, or promotional pricing. It’s always worth asking before you sign up as some offers often aren’t advertised.

• Pack smart. The more efficiently you organise your items, the smaller (and cheaper) the unit you’ll need. Disassemble large furniture where possible and use uniform-sized boxes to maximise vertical space.

• Time it right. Avoid peak periods like summer and the Christmas–January window if you can. Booking in autumn or mid-year often means better availability and more competitive pricing.

• Read the fine print. Ask for a full breakdown of fees upfront: deposits, insurance, access charges, and any rate-increase clauses in the contract.

• Factor in the full moving cost. Storage is just one part of the equation. Don't forget to budget for getting your things there. There are also hidden DIY moving costs worth knowing about before you go it alone.
