Prohibited Items
Overrun exists to move surplus building material to someone who can use it. Some material cannot be moved safely or lawfully, and this page names it. It forms part of our Terms of Service, and every seller confirms they have read it before publishing a listing.
Material that cannot be listed
The following cannot be listed on Overrun in any condition, at any price, including free. Describing the risk in the listing, marking it “for disposal”, or asking the buyer to accept it “as is” does not make the listing acceptable.
Asbestos and asbestos cement
Overrun does not permit asbestos in any form, for any reason, under any circumstances. This is our rule and it has no exceptions. It covers friable asbestos and bonded asbestos cement in every product it was made into — fibro and AC sheet, corrugated and “super six” roofing, ridge capping, eaves and soffit lining, flue pipe, downpipe, water and drainage pipe, backing board behind wet-area sheeting and switchboards, and vinyl or lino with asbestos-backed underlay. It applies whether the material is broken or intact, weathered or sealed, painted, encapsulated, or still fixed in place, and it applies to offcuts and part sheets as much as to full ones.
The supply of asbestos is restricted under the WHS Regulations in every Australian state and territory. We are not the authority on how those rules apply to your work.
A Class A or Class B asbestos licence makes no difference to this rule. Nothing on Overrun distinguishes a licensed seller from an unlicensed buyer, so we do not permit the material regardless of who is listing it.
Unverified pre-1990 building material
Material that came out of a building constructed or last refurbished before 1990, where you cannot say what it is made of, is prohibited. Sheeting, lining, roofing, insulation, pipe, and floor covering from that era were commonly asbestos-containing, and an unidentified sheet is indistinguishable from a prohibited one.
The one route to a compliant listing: a written analysis from a NATA-accredited laboratory identifying the material, with the laboratory’s name and the date of the report stated in the listing. Age of the building, a supplier invoice, a builder’s recollection, and visual identification are not analyses and are not accepted.
Lead-painted timber
Timber carrying paint that contains lead, or paint of unknown composition applied before 1997, is prohibited. That includes weatherboards, architraves, skirting, window frames, sashes, doors, and fascia recovered from painted pre-1997 buildings.
Cutting, sanding, or burning lead-painted timber releases lead dust and fume, and the person exposed is usually the buyer, in a home workshop, without knowing what is in the paint. Stripped timber may be listed only where the paint has been fully removed and the listing says so.
Treated pine from an unknown source
Treated pine may be listed only when you can state the treatment. If you cannot say whether it is CCA, ACQ, LOSP, or creosote, it is prohibited.
CCA-treated timber contains arsenic and chromium, and restrictions apply to where it can be used and to burning it. A buyer who does not know the treatment cannot make that decision at all, which is why we need it stated. Offcuts with no visible tag or brand, and salvaged timber of uncertain history, fall under this prohibition.
Insulation and glass containing hazardous fibre
Prohibited: insulation containing amosite, crocidolite, or any amphibole asbestos; loose-fill asbestos insulation of the “Mr Fluffy” type; refractory ceramic fibre board, blanket, and rope; and any insulation whose fibre content you cannot state.
Also prohibited: glass wool, mineral wool, rock wool, and glass or glazing products whose composition is unknown, where they have been removed from a building and are being passed on. Batts in original packaging with the manufacturer, product name, and R-value legible on the bag are acceptable.
What happens when a listing breaches this policy
Reports go to a moderation queue and are reviewed by a person. Anyone can report a listing, signed in or not, using the Prohibited item reason on the listing page. We also act on listings we find ourselves.
- The listing is removed from public view immediately. Removal does not wait for the seller to reply, and it is not a negotiation. Nothing is deleted — the listing and its messages are retained as a record of what was published and when.
- The seller is told which material and which clause. Where the breach is genuine ambiguity rather than the material itself — unstated timber treatment, missing laboratory analysis — the seller may republish once the listing states what this policy requires.
- Asbestos is not a warning. A listing offering asbestos or asbestos cement results in immediate removal and suspension of the account. Suspension hides every listing the account holds and blocks access; it is reversible, and it is not reversed on the basis that the seller holds a removal licence.
- Repeat breaches end the account. A second breach after a warning, or any attempt to relist removed material under a different title, category, or account, results in suspension without a further warning.
- We may report the listing to the relevant authority. That includes the work-health-and-safety or environmental regulator in the state the material is in. Where we do, we provide the listing, the account details, and the messages associated with it.
Removal under this policy does not entitle a seller to a refund of any membership fee, and it does not depend on whether the material sold before it was removed.
Where responsibility sits
The seller is responsible for what they list, for identifying it correctly, and for complying with the law that applies to it in their state. Overrun does not inspect, test, handle, transport, or take possession of any material listed on the site, and publishing a listing is not a representation by us that the material is safe, lawful, or as described.
Nothing on this page is legal advice, and it does not replace the duties a licence holder, principal contractor, or occupier already has under work-health-and-safety and environmental law.
Reporting something you have seen
Use the report link on the listing, or email hello@overrunau.com.au with the listing URL. If material has already changed hands and you believe someone is at risk, contact the work-health-and-safety regulator in your state as well — we can remove a listing, and we cannot recover material that has already been collected.
Changes to this policy
We update this page as we encounter material that belongs on it. The “Last updated” date at the top shows the current version. Sellers confirm this policy at each publish, so a change takes effect on the next listing rather than retrospectively.
