Buying an over bonnet storage unit in Australia typically costs $1,700 to $2,100 outright, plus a delivery and installation fee of roughly $150 to $450 depending on your metro area and site access. Renting sits between $25 and $30 a week. If you own your apartment or plan to stay put for more than a year or two, buying usually wins on cost. Renting suits tenants or anyone still waiting on body corporate approval.
Prices generally fall into a few bands, and knowing where a quote sits helps indicate the type of unit being purchased.
Entry-level mesh or half-mesh cages start lower, often in the $1,000 to $1,500 range, but they trade off security and weatherproofing. Mid-range steel units, the ones most apartment residents end up choosing, land between $1,700 and $1,900. Premium all-steel models with heavier load ratings and longer warranties push toward $2,000 to $2,100 or beyond.
Storagenest's own product, The Kookaburra, sells for $1,749 as a one-off purchase, with delivery and professional installation quoted separately for your location.
What's usually included in that headline price:
What commonly gets added on top:
Vendors routinely quote the cabinet price as the headline figure while delivery, installation, and any accessories appear as line items further down the quote. Read the full breakdown before comparing two suppliers on price alone.
Size is the biggest lever. Internal volume around 2.3m³, which is common for full-size units like the Kookaburra, costs more than a shallow half-mesh cage but holds considerably more gear, from bikes and camping equipment to seasonal storage boxes.
Material and finish matter more in Australia than buyers expect. Coastal humidity in Gold Coast, Sunshine Coast, and Brisbane apartment car parks accelerates corrosion on cheaper powder-coated steel. Electrocoated finishes resist rust better in salt air and typically carry a small premium over standard coatings, though that premium is the point of paying it.
Security features shift the price too. Multi-point locking steel panels cost more than a single hasp lock but matter if your car park has public or shared access.
Pro Tip: Ask suppliers whether their steel finish is rated for coastal exposure before comparing two quotes on price alone. A cheaper unit that rusts in three years costs more than a pricier one that lasts a decade.
Delivery and installation fees are almost always billed separately from the unit price, and they vary by location and site access.
The right model depends almost entirely on how long you expect to occupy the bay.
Renting suits short-term tenants and anyone unsure how long they'll stay. Storagenest's rental plans run $25 per week on a 12 month term or $29 per week on a 6 month term, both through the rental plans page. Over a year, that's roughly $1,300, cheaper than buying outright only if you move before the breakeven point.
Buying outright makes sense once you pass that breakeven, typically somewhere between 12 and 18 months of rental payments. At typical prices around $1,749 for the unit plus $149 to $199 install fee, owners recoup the cost against rental pricing within that window and then own the asset outright.
Most apartment complexes require body corporate or strata approval before any structure goes above a car bonnet, and the concerns are consistent across buildings: is it a permanent fixture, does it look reasonable, and does it create any safety hazard for pedestrians or other vehicles.
Suppliers who've done this before usually provide a documentation pack to smooth the process:
Approval delays cost you time, not necessarily money, but a rushed or incomplete application sometimes triggers a change in installation method partway through, which can push the install fee higher. Storagenest's body corporate approval support exists specifically to reduce that risk.
Pro Tip: Submit your body corporate application with the supplier's documentation pack attached from day one. Committees approve faster when they don't have to chase you for photos or specs.
A mid-range unit like the Kookaburra gives you roughly 2.3m³ of internal volume and a load capacity up to 500kg, enough for tools, bikes, camping gear, and seasonal boxes without worrying about overloading the frame. Some premium units on the Australian market advertise similar 500kg load ratings paired with 10-year warranties, a combination worth checking if you're buying rather than renting.
Long warranties and solid load ratings matter more to owners than renters, since they're the ones carrying the asset for years rather than months. If you're buying for the long haul, treat warranty length as seriously as the sticker price.
The Kookaburra is a freestanding, all-steel over bonnet storage unit built for apartment car parks, with roughly 2.3m³ of internal volume and a load capacity of up to 500kg. Professional installation is typically completed in under two hours, including a site measure to confirm fit before the unit goes in.
Because it's freestanding and doesn't require permanent fixing to the building structure, installation time drops compared to units that need drilling or bracketry, which keeps the install fee at the lower end of the market range. That combination of speed and a non-permanent design also tends to simplify the body corporate approval conversation, since committees see less structural risk in something that can be removed cleanly if a resident moves out.
Over bonnet storage units carry very little in the way of ongoing costs, which is one of the quieter advantages over other storage solutions. There's no subscription, no service contract, and no recurring maintenance fee tied to owning the unit outright.
The main cost that can appear later is replacement of the lock mechanism if it wears out or a key gets lost, which most locksmiths handle for a modest call-out fee rather than anything supplier-specific. Coastal owners should budget for an occasional inspection of the steel finish, particularly around door hinges and lock housings where moisture collects, though this is closer to a five-minute check than a paid service.
If you're renting rather than buying, the weekly fee already covers the unit itself, and most rental agreements shift responsibility for damage or excessive wear back to the supplier rather than the tenant, though it's worth confirming this in the specific rental terms before signing. Buyers carry the small long-term maintenance load themselves, but given there are no moving parts beyond the lock and hinges, that load stays light for the life of the unit.
The absence of a service fee is part of what makes the total cost of ownership calculation for buying relatively simple: unit price, plus one-off installation, plus near-zero ongoing spend.
Steel over bonnet units are built to outlast most other apartment storage solutions, largely because they're not exposed to the same weather cycling as an outdoor shed or an unenclosed cage. A well-finished unit, particularly one with electrocoated or corrosion-resistant steel, can reasonably be expected to last a decade or more with only light upkeep.
Depreciation works differently for storage hardware than for vehicles or electronics. There's no resale market tracking these units closely, but the practical depreciation curve is shaped almost entirely by finish quality and coastal exposure rather than age alone. A basic powder-coated unit in a humid coastal car park might show surface corrosion within three to five years, while the same unit inland could look nearly new after a decade.
That's why warranty length is a genuinely useful proxy for expected lifespan when you're comparing quotes. A supplier offering a Lifetime Parts Cover is making an implicit claim about how long the steel and locking mechanism are expected to hold up, and it's a more honest signal than a low sticker price on its own. Premium units advertising 10-year warranties alongside heavier load ratings are effectively pricing in a longer expected service life.
For owners weighing buy versus rent, this lifespan matters directly. If a $1,749 unit lasts ten years, the annualised cost drops to roughly $175 a year before installation, which comfortably undercuts even the cheaper 12 month rental plan over any multi-year stay.
Total cost of ownership pulls together the purchase price, the one-off installation fee, and whatever light maintenance crops up over the unit's working life, and running the numbers on a typical scenario is more useful than any single sticker price.
Take a Gold Coast apartment owner buying a Kookaburra outright: $1,749 for the unit, plus $149 to $199 for delivery and installation, brings the initial outlay to somewhere between $1,898 and $1,948. Assuming minimal ongoing costs beyond an occasional lock service, and a working life of ten years given a coastal-resistant finish, that works out to under $200 a year of storage space that would otherwise sit unused.
Compare that against a tenant renting the same style of unit on a 12 month plan at $25 a week. Over three years, that's roughly $3,900, more than double the outright purchase cost, though the tenant avoids any upfront capital outlay and can walk away without a resale problem if they move.
A body corporate buying units in bulk for multiple bays faces a slightly different equation. Buying outright across, say, six bays means a larger upfront spend, but it removes any ongoing rental administration and locks in a fixed, predictable cost per bay rather than a recurring line item on the strata budget. For most owner-occupiers and long-term investors, the maths favours buying once you're confident the tenure will run past roughly 18 months.
Regional pricing in Australia follows a fairly predictable pattern: unit prices themselves don't shift much by location, since steel manufacturing costs are national, but delivery and installation fees climb the further you get from a supplier's home base.
Metro areas like Brisbane, the Gold Coast, and the Sunshine Coast typically see the lower end of installation fees, in the $149 to $199 range for suppliers with an established local presence. Regional towns further out, or apartment complexes in areas without a nearby installer base, can expect higher delivery charges simply because of travel time and fuel, sometimes pushing the total delivery and install cost toward $350 to $450 based on examples from suppliers operating across wider service areas.
Access also plays a bigger role regionally than in the city. A regional apartment block might have simpler car park access than a dense inner-city building with boom gates and lift-only entry, which can offset some of the higher travel fee with a faster, simpler install. If you're outside a major metro area, ask upfront whether the quoted delivery fee already accounts for your postcode or whether it's a placeholder estimate pending a formal site check.
Property managers overseeing complexes in multiple regions should expect some fee variation between buildings even from the same supplier, and it's worth requesting a written breakdown per site rather than assuming one quote applies uniformly across a portfolio.
Getting quotes that are actually comparable takes a bit more than asking "how much for a unit." Request the same information from every supplier so you're matching like with like.
Ask each supplier for the unit price, the delivery and installation fee separately, the exact internal volume and load capacity, and the warranty terms in writing. A quote that bundles everything into one number without breaking out installation makes it hard to spot which supplier is actually cheaper once site access or regional travel fees are factored in.
Confirm whether the quote includes a site measure before the unit ships, since this step catches fit issues that would otherwise turn into a costly reinstall or restocking fee. Also ask whether the supplier provides body corporate documentation as standard, because chasing that paperwork separately after signing adds weeks to your timeline.
Finally, compare warranty length against price rather than treating price as the only variable. A unit that costs $150 more but comes with a Lifetime Parts Cover and a coastal-rated finish is very likely the cheaper option once you annualise the cost over its expected lifespan. Get at least two written quotes before committing, and don't be shy about asking a supplier to clarify any line item that looks vague.
Buy if you're staying long-term. Rent if your tenure is shorter than roughly 18 months or approval is still pending. Coastal sites, custom fits, or complicated strata committees all push the real cost higher than the sticker price, so budget accordingly. Choose a supplier who handles the site measure and body corporate paperwork upfront. That's where most quote surprises come from.

Storagenest sells one product, the Kookaburra, and skips the guesswork that comes with comparing a dozen mesh cages and steel lockers against each other. If you own your apartment and plan to stay, the $1,749 outright purchase of The Kookaburra works out to about the same as 70 weeks on the $25-a-week plan. If you're a tenant or still waiting on strata sign-off, the 12-month plan at $25 a week or the 6-month plan at $29 a week gets you storing gear without the upfront cost.
Every quote includes a site measure to confirm the unit fits your bay, an upfront fee estimate for delivery and installation, and a body corporate documentation pack if your building needs sign-off. Request a free quote through Storagenest's how it works page or head straight to the Kookaburra product page to lock in pricing before your next strata meeting.
Buying an over bonnet unit typically costs $1,700 to $2,100, with Storagenest's Kookaburra priced at $1,749 one off. Delivery and installation add $149 to $199 through Storagenest, or up to $450 for some suppliers in less accessible regions.
Over bonnet units are typically bought outright or rented weekly rather than billed monthly. Storagenest's rental plans cost $25 per week on a 12 month term or $29 per week on a 6 month term, as shown on the rental plans page.
Over bonnet storage is a steel storage unit installed above the bonnet space in a car park bay, giving apartment residents secure storage without losing their parking spot. Units like the Kookaburra offer roughly 2.3m³ of internal volume and up to 500kg load capacity while sitting entirely above the vehicle.
Professional installation for a freestanding unit typically takes under two hours and costs $149 to $199 with Storagenest, including a site measure to confirm fit. Fees can run higher in regional areas or buildings with difficult access, sometimes reaching $350 to $450.
Yes, for most owners staying longer than about 18 months. A $1,749 outright purchase plus installation breaks even against a $25 a week rental plan within roughly a year and a half, after which buying is clearly cheaper.
