Self-storage has seen phenomenal growth, leading to an influx of new players and supply – but experts insist demand can keep pace. Here’s how investors can cash in.
Our booming population, denser cities, unaffordable housing that squeezes families into smaller homes, and ongoing love of renovations create endless demand for stashing our stuff.

Australia’s self-storage market, valued at nearly $3.14 billion in 2025, is projected to grow at a robust 4.3% annually to $4.78 billion by 2035, according to an Expert Market Research report.
Linda Sharkey, managing director of specialist self-storage advisory Four Leaves, said that demand is surging from every angle.
“It’s not just people moving, decluttering and renovating; demand also comes from deaths, divorces, merging or separating families, as well as small- and medium-sized businesses in transition,” Ms Sharkey said.
The pandemic turbocharged the sector as deaths, divorces and lockdown reshuffles collided with a housing boom and spare cash.
“Some states saw self-storage grow by 20% in one year, which was phenomenal,” Ms Sharkey said. “Operators were raising their rates so that customers would leave, because the next customer was prepared to go in much higher.”

At the same time, businesses piled up inventory buffers against delays, shortages and soaring freight costs, according to REA Group senior economist Anne Flaherty.
“The pandemic highlighted how essential self-storage can be,” she said. “But as businesses face more uncertainty, storage space is definitely expected to grow.”
A ‘boon’ investment?
This double-digit revenue growth during the pandemic has fuelled new storage facilities, pushed up prices, and lured large players to the space making large-scale transactions.
December’s blockbuster $4 billion Brookfield-GIC buyout of National Storage REIT (real estate investment trust) set records as Australia’s biggest REIT privatisation, while Chapter + Co’s sale of six assets totalling 48,000sqm along the eastern seaboard for an expected $220m is drawing local and offshore interest.

Chapter + Co’s portfolio represents the largest privately-held self-storage portfolio, and expressions of interest on its blockbuster divestment close on Thursday, 7 May – its managing agent is CBRE’s Paul Ryan.
“Despite current market volatility, we are seeing self-storage assets continue to be in high demand with investors attracted to inflation protected income, high cash yield and an attractive growth outlook,” Mr Ryan said.
But it’s not just demand from consumers and business that make this sector attractive. Its real edge is its resilience, simplicity and pricing agility, according to Ms Flaherty.

“The fact that you can adjust pricing depending on market conditions is a big boon, because often with other kinds of commercial assets, you’re locked into a lease term for several years,” she said.
“This also makes it less risky, because if demand goes down, you just adjust the pricing point down.
“It’s also relatively hands-off, in contrast to owning and managing a shopping centre, for example, which has a lot more complexity to it.”
Precinct in Oakleigh has 49 self-storage sites and is for sale on realcommercial.com.au.
Tenants are also pretty sticky, Ms Sharkey said.
“Generally, you can bank on a customer staying for 12 months. It’s a bit like a gym membership – people just keep paying it. And businesses tend to stay for longer and absorb free rate rises more easily.”
A favourable outlook – sustainable growth?
Ms Sharkey says no industry can sustain double-digit growth forever, but yields remain stronger than traditional assets, with Sydney around 5%, Melbourne 5.5%-5.75% and regional areas up to 7%.
Self Storage Association of Australia’s 2025 data shows there are 3,380 self-storage facilities across Australia and New Zealand (that are around 85% occupied), with 350 major developments underway – yet only 9.2% of the adult population use them.

Ms Sharkey says Australia remains undersupplied.
“We have roughly two-thirds the amount of supply that they have per capita in the United States — our market can absorb a lot more supply,” she said.
CBRE National Director of Alternative Assets, Dylan Adams, says supply remains constrained by planning settings, site availability and development feasibility, particularly in inner-urban markets.
“While some pockets may see elevated levels of new delivery, there is no evidence of systemic oversupply, with strong demand fundamentals continuing to absorb new supply across most major metro markets,” he said.
“We expect deal activity to continue to build, driven by portfolio recycling, ongoing sector consolidation, and new entrants seeking scale in what is becoming an increasingly institutionalised asset class.”

But Vanessa Rader, Head of Research at Ray White, warned cost-of-living pressures and young people’s buy-less-resell-more mindset may deter some.
“Younger people aren’t collecting quality furniture worth storing. Second-hand market platforms like Facebook Marketplace let them buy and resell cheaply and avoid high storage costs.”
But businesses remain a prime market, she said.
“For many businesses, self storage is more flexible and cheaper than leasing their own facilities.”

How to invest in self-storage
Self-storage attracts REITs, private equity and seasoned capital – and isn’t an easy investment class for newcomers to enter.
Institutional giants like Storage King, National Storage and Kennards own and operate their own assets; plenty of deals are done off-market, which experts say prevents customer flight and hides performance from rivals.
Top performing assets are tightly held, and warehouse space remains scarce nationwide, but entry paths exist, Ms Sharkey said.
This mega storage facility in North Rocks, in Sydney’s hills district, is for sale on realcommercial.com.au.
“Underperforming assets can miss demand-based pricing, like charging premiums for scarce unit sizes. A well-rounded facility will optimise rates every day, just like an airline,” she said.
“There’s scope to turn a 5%- 6% return into an 8% return just by managing it correctly.”
You can buy a facility and outsource to pros like Storage King, CBRE or Wilson Storage to manage it; launch and run your own self-storage business; or buy shares in sector syndicates or trusts.
While running a self-storage facility may seem simple, expertise should not be underestimated, Ms Sharkey said.
A 340sqm site at this storage facility in Direk, on the fringes of Adelaide, is for sale on realcommercial.com.au.
Ms Flaherty said while large players have brand presence, there’s still space for small players.
“There’s growing demand for self-storage, so that creates an opportunity in areas where there’s a shortage,” she said.
Urban areas may offer stronger demand, but warehouse space is in shorter supply and pricier.
Ms Sharkey advises investors to analyse supply-demand fundamentals in the facility’s 15-minute radius.
“When two or three operators open a facility at the same time, you have this price war, though this oversupply is temporary,” she said.
“Once the facility reaches a stabilised level of occupancy, rate optimisation can come back in again.”
