What Can and Can't Go in a Skip Bin
Most of what comes out of a house, a garden or a renovation goes straight in a skip bin without a second thought. The list of things that can’t is short – but it’s short for good reasons, and a few of the items on it are ones people throw in every day without realising there’s a problem.
Here’s what can go in a skip bin, what needs to be declared first, and what can never go in under any circumstances.
What can go in a skip bin
Standard general waste covers the vast majority of household and renovation rubbish:
Household – furniture, mattresses (declare them), clothing, linen, curtains, carpet and underlay, boxes, paper, books, toys, kitchenware, crockery, sporting gear, bikes, general junk.
Garden – grass clippings, leaves, prunings, branches, weeds, bark and mulch.
Renovation and building – timber, plasterboard, tiles, bricks, concrete, rubble, insulation, roofing, cabinetry, packaging.
Office and commercial – desks, chairs, shelving, partitions, filing cabinets, packaging and cardboard.
The important qualifier is that the bin has to match the waste. A general waste bin takes almost anything on that list. A green waste or hard fill bin doesn’t – more on that below.
Items you need to declare before they go in
These are accepted, but they cost more to dispose of and need to be mentioned when you book rather than discovered at the weighbridge.
Mattresses. Stripped and processed separately rather than landfilled whole.
Fridges, freezers and air conditioners. Must be degassed by a licensed technician before disposal – the refrigerant gases can’t simply be released.
Other whitegoods. Washing machines, dryers, dishwashers, ovens. Mostly recoverable metal.
Televisions, computers and monitors. Electronic waste is banned from landfill in metropolitan Adelaide and various other jurisdictions, so it has to go to an e-waste recycler.
Tyres. Separate disposal pathway, and a common surcharge item.
None of these are a problem. Burying one at the bottom of the bin and hoping is – it turns up on the invoice as a variation, which nobody enjoys.
What can never go in a skip bin
The genuinely prohibited list is fairly consistent across Australian operators, because the reasons behind it are the same everywhere.
Asbestos
Never in a general bin, under any circumstances. Asbestos requires a specialised wrapped bin, licensed disposal and documentation, and depending on the quantity and type, a licensed removalist to take it out in the first place.
It’s common in Australian homes built before the late 1980s – behind bathroom wall tiles, under vinyl flooring, in eaves, garage walls, fences and shed roofing. You can’t identify it by looking; the only way to know is a sample tested by an accredited laboratory. If you suspect it, stop work on that area and get it tested before going further.
Liquids and chemicals
Paint, solvents, thinners, adhesives, engine oil, brake fluid, fuel, pesticides, herbicides, pool chemicals, cleaning concentrates.
Liquid waste leaks. In a bin sitting on a driveway it runs into stormwater; at a transfer station it contaminates everything around it. These all have dedicated household hazardous waste drop-off points, usually free for domestic quantities.
Gas bottles and aerosols
BBQ bottles, camping canisters, oxy and acetylene, spray cans – even ones that feel empty.
They’re pressurised. When a bin is tipped and the contents are compacted or crushed, a gas bottle becomes a genuine explosion risk to the operator standing next to it. Swap empty BBQ bottles at any exchange point; aerosols go to hazardous waste.
Batteries
Car batteries, household batteries, power tool packs, laptop and phone batteries, and anything with a battery sealed inside it – vapes, toys, electric toothbrushes, cordless tools.
This one deserves its own section, below.
Clinical and medical waste
Sharps, syringes, dressings, and anything from home-based care. These need a clinical waste stream. Pharmacies and councils can direct you.
Medications go back to any pharmacy for safe disposal, free of charge. Don’t bin them and don’t flush them.
Fluorescent tubes and globes
Mercury content. Separate disposal, and many hardware stores accept them.
Contaminated soil
Soil suspected of contamination – from former industrial land, imported fill of unknown origin, or anywhere with fuel staining or fibro fragments through it – has to be assessed and classified before disposal, and goes to a facility licensed for that classification.
Ammunition, flares and fireworks
If you find any of these – and deceased estates turn them up more often than you’d think – contact the police for instructions. The same applies to firearms.
Fire extinguishers
Pressurised. Most fire equipment suppliers will take them back.
The battery problem
Batteries have quietly become one of the biggest safety issues in Australian waste management, and lithium-ion ones in particular.
When a lithium battery is crushed or punctured – which is exactly what happens inside a compactor truck or at a transfer station – it can enter thermal runaway and ignite. It burns extremely hot, it’s difficult to extinguish, and it does it in the middle of a load of paper, cardboard and timber. Fires in collection trucks and waste facilities from concealed batteries are now a well-documented and growing problem across the country.
The difficulty is that batteries hide. People know not to bin a car battery. Far fewer think about:
- Disposable vapes
- Cordless tool battery packs
- Old laptops, tablets and phones
- Kids’ toys with sealed battery compartments
- Electric toothbrushes and shavers
- Bluetooth speakers and headphones
- Power banks
- E-bike and scooter batteries
If it holds a charge, it doesn’t go in the bin. Battery drop-off points are now widely available at supermarkets, hardware stores, council depots and many electronics retailers, and they’re free.
It depends which bin you've hired
A lot of “can I put this in” questions aren’t about safety at all – they’re about keeping a load clean.
Green waste bins take garden material only. Plastic pots, seedling trays, weed matting, treated timber, sleepers, fence palings, soil, rocks and general rubbish all contaminate the load. One plastic bag can reclassify an entire bin as general waste, at general waste prices, because the composting facility won’t take it.
Heavy waste bins come in two kinds. A clean fill bin takes clean concrete, soil, sand and rock. A mixed heavy bin takes a combination of concrete, bricks, tiles, pavers, rubble and soil. Timber, plasterboard, plastic and general rubbish don’t belong in either – keeping the load to heavy material is what keeps it at heavy waste rates.
General waste bins are the forgiving option. Everything on the “can go in” list, mixed, sorted at the facility. It costs more per tonne precisely because of that sorting.
The practical upshot: if a job produces two clean streams, two bins are usually cheaper than one mixed one.
What about paint?
The most common single question, and the answer is simple: paint stays out of the skip bin, whether it’s wet or dried in the tin.
Leftover paint is easy to get rid of properly. Household hazardous waste depots take paint free for domestic amounts, and Paintback collection points at many paint retailers and council depots accept leftover tins at no charge.
Set the tins aside as you clear out, and drop them off in one trip once the job is done.
What happens if you put something prohibited in anyway
Nothing good, and it’s rarely worth it.
Loads are inspected. A prohibited item found at the weighbridge means the load is rejected, which means a return trip and a disposal problem that’s now sitting back on your driveway. Contamination charges apply. For serious items – asbestos in particular – there are potential regulatory consequences beyond the commercial ones.
More to the point, most of the prohibited list exists because of risk to the people handling it. The driver lifting the bin and the staff at the transfer station have no way of knowing there’s a gas bottle under the plasterboard until something happens.
If you’re not sure about an item, ask when you book. It’s a thirty-second conversation.

Frequently Asked Questions
Can I put a mattress in a skip bin?
Yes, but declare it when you book – it carries a surcharge because it’s processed separately.
Can I put a fridge in?
Yes, once it’s been degassed by a licensed technician. Tell us at booking.
Can I mix garden waste and general rubbish?
You can, but you’ll pay general waste rates for the lot. Kept separate, a clean green load is cheaper.
Is treated timber allowed?
In a general waste bin, yes. In a green waste bin, no – treated and painted timber contaminates the composting stream.
What about food waste?
Small amounts from a house clean-out are fine. Commercial quantities need an organics service.
Can I put in a bit of soil with the bricks?
Yes – book a mixed heavy bin. It’s built for exactly that combination of soil, brick, concrete and rubble.
What if I'm not sure about something?
Ask before it goes in. It’s much easier than sorting it out afterwards.
Not sure what you need?
Tell us what you’re clearing out and we’ll point you to the right bin – and flag anything that needs handling separately before it arrives.
