A container is steel, so people assume it is the safe place to put things. Steel conducts heat beautifully, which is exactly the problem. Placement is what matters.
The country north and west of Tewantin — Cooroibah, Cootharaba, Ringtail Creek, Boreen Point and over the ridge to Kin Kin — is bush blocks on sandy soil, with long single-entry driveways and a lot of standing fuel. Anyone who has owned acreage up there through a dry spring already knows that. It changes two practical things about owning a shipping container: where you put it, and what you expect of it.
We get asked fairly often whether a container is a good place to keep valuables "in case of fire". The honest answer is the uncomfortable one, so let us get it out of the way first.
Corten steel will not burn. That is the whole of the good news, and people over-read it. The things that go wrong in a fire are:
Radiant heat. A steel box sitting in the path of radiant heat gets hot right through. The steel conducts, the air inside heats, and the contents cook. Plastics deform, aerosols and batteries become a hazard of their own, paint blisters, timber and fabric scorch. Nothing has to catch alight inside for the contents to be ruined.
Embers. A container is not sealed like a safe. There are vents along the top rail, and the cargo doors seal against rubber gaskets that are made to keep rain out, not embers. Fine debris gets in through both, and a container with dry leaf litter blown into the bottom corners has fuel inside it.
What it is standing in. Most of the damage we hear about afterwards is not the container, it is the metre of grass around it. A box in long grass, up against a fence line, under a tree, or beside a woodpile is sitting in the fire.
So: do not treat a container as a fire refuge, and never shelter in one. Do not plan on it protecting photographs, documents or anything else irreplaceable. That is the same advice we give about flooding, for the same reason — we would rather be straight with you about what a steel box can do than sell you a comfortable idea. If you want the longer version of that argument, our flood-season piece makes it about water.
Here is the flip side, and it is a real one. A container can be placed. A shed is wherever its slab is, permanently. A container goes where you decide, and can be shifted later if you got it wrong.
On a bush block that matters, because the useful thing you can do is put your secure storage somewhere with space around it — away from the house, away from the heaviest fuel, on ground you have cleared and keep cleared. That is a choice a shed does not give you once it is built. The same goes for the gear you want out of the house: mowers, tools, fuel-free machinery, camping kit, the things that make a block workable.
Walk the block before you order, not after the truck is booked. The things worth thinking about:
Separation. Give it clear space on all sides, kept mown or scraped back. Not in the grass, not against the fence, not under a tree that drops limbs, not tucked beside the woodpile or the gas bottle cage.
Not in the way. A container is heavy and it is staying put. Do not place it where it narrows your driveway, blocks a turning circle, or gets between the house and the only way out. If a fire appliance ever needs to come up your drive, it needs the room.
Ground you can keep bare. Sand, gravel or scraped dirt under and around it is better than grass, and it also keeps the underside dry, which is what makes a container floor last.
Doors facing the way you will use it. Cargo doors swing wide and need more clearance in front than people expect. Face them at the way you will drive or walk up to it.
Shade, if you have the choice. The long western wall in full afternoon sun makes the inside unpleasant from about two o'clock in summer. Where the block allows it, put the long side to the south.
Blocks through Cooroibah and Cootharaba sit on sand, and sand behaves differently from the clay out west of Gympie. It drains well, which is in your favour. It also moves, and it does not spread a point load.
A container carries its whole weight on four corner castings. On sand, small pads sink, and a container that settles unevenly stops closing its doors properly — which is the first thing you notice and the most annoying thing to fix. Use something with real footprint under each corner: wide concrete pads, hardwood sleepers laid flat, or a proper footing if you are putting it somewhere permanent. Level it across the diagonal, not just along one side.
Keep an eye on it through the first wet season. Sand shifts after heavy rain, and a tap of a packer under one corner early is easier than a re-level later.
The driveways up there are the limiting factor more often than the block is. A loaded tilt-tray wants a firm, reasonably straight run and room to tip; sand tracks with soft shoulders, tight bends between trees, and overhanging limbs all decide which truck we send — or whether we can send one at all that week.
The fix is cheap: send us photos of the entry, the track and the drop spot before you order. We would much rather tell you the truth about access from your photos than have a driver work it out at your gate. We have written the access side up properly in our acreage guide, and it applies just as much on sand as it does on the Mary Valley flats.
Two short rules, and they are about the container being a closed steel box rather than about fire specifically. Gas bottles do not belong inside one. Nor do jerry cans of petrol, mower fuel, or aerosols left to sit through a summer. A closed container in the sun gets hot, and vapour has nowhere to go. Store fuel and gas in a ventilated spot away from the box, which is what your supplier and your insurer will both tell you.
Chainsaws, brushcutters and mowers are fine stored dry and empty, and on a bush block that is most of what ends up in there.
For storage you care about, buy cargo-worthy. Those units are checked and sold wind and watertight, which is what keeps rain off tools and keeps leaf litter and dust out of the corners.
Our as-is stock is the cheap rung and we sell plenty of it, but it is sold as seen and it is not sold watertight. It earns its keep as a hay store or a rough lockup for fencing gear. It is the wrong buy for anything that has to stay dry.
Ask and we will send photos of your actual unit before it is delivered, serial number visible, so there are no surprises when it lands.
On sizes, a 20ft fits down most bush driveways and gives about six metres of wall. A 40ft needs a sidelifter and a lot more working room than a Cooroibah track usually offers. A high cube is worth it if you will be racking it out.
The boundary matters up here. Cooroibah, Cootharaba, Boreen Point, Kin Kin, Cooroy and Pomona sit with Noosa Shire; country north of the range falls under Gympie Regional Council. A container used as storage is treated differently from one that is substantially modified or lived in, and bushfire and vegetation overlays on your particular lot matter more than any general rule.
We are container people, not certifiers. Ring the council with your lot and plan number before you do anything permanent, and talk to your local brigade about placement if fire planning is the reason you are asking. Both conversations are free and both are worth more than a forum thread.
Permanent storage on a block you own is usually a purchase. Hire suits a build, a clean-up or a rebuild, and hire units go out cargo-worthy, wind and watertight. Freight is quoted with the container, because it depends on where you are and what the access looks like — one call gets you an exact number rather than a guess.
If you are up that way and want a straight answer about whether a truck will reach your spot, ring 0487 176 951 with your address and a couple of photos. If a container is the wrong answer for what you are trying to protect, we will tell you that too. Heading up the valley instead? The upper Mary Valley has its own set of problems.
Soft ground, steep tracks, long driveways — what actually matters when your container is going onto a property in the Gympie region, not a suburban block.
Above Kandanga the Mary Valley narrows, the road gets interesting and the council boundary stops being obvious. We deliver up there regularly — this is what we have learnt about the access, the ground and which council you are actually in.
People ring us most weeks about building a container home in the Mary Valley or the hinterland. Here is the honest version — where the money really goes, what the councils treat as a building, and when it does genuinely work.
One form, one delivered number.
