Second-hand child restraints fail in boring ways. The tether is missing. The instruction book is missing. The shell was in a crash and looks fine. The date stamp is older than the ten-year horizon Queensland mentions. The cover has been replaced with something that no longer matches the harness routing. The seller is honest and still does not know the seat’s history.
Queensland’s public advice is the spine of this page: prefer a restraint less than ten years old, do not use a seat that has been in a crash, and get a copy of the manufacturer’s instructions. Kidsafe’s consumer material is in the same key. This site will not invent a “safe if it looks new” test.
## A checklist you can actually use
Ask for the model name and manufacture date. Search ACCC recalls. Ask whether the seat has been in a crash, including a crash that “wasn’t that bad”. Inspect the shell for cracks, the harness for fray, the buckle for sticky release, the tether for missing hardware. Refuse a seat with no label. Refuse a seat whose label is not AS/NZS 1754. Refuse a seat that arrived in Australia in a shipping container as a favour.
Then have a fitter look at it before the first school run. A fitter cannot restore crash history that nobody wrote down. They can tell you the seat is incomplete.
Marketplace listings on the old /baby-car-seat-classifieds/ path are gone. The path now teaches this checklist instead of hosting strangers’ ads.
This page is general information for Australian readers. It is not safety advice, a product ranking, or a fitting service. Always read the restraint label and the manufacturer instructions, confirm the current rule with the road agency in the state or territory where you are driving, and have the finished install checked by an authorised fitter.

When second-hand is the wrong tool
Newborn month, when you have no time to verify history. A seat offered without a label. A seat that has lived in a crashed car. A seat older than the ten-year horizon TMR mentions. Those are times to buy new or to hire an approved seat from a programme that can show you the paper, not times to negotiate.

A longer reading path from this hub
If you arrived here from search, stay long enough to open three other URLs: the ages and stages table, your state page, and either installation or buying depending on whether the seat already exists. That triangle — stage, jurisdiction, physical install or purchase — is the whole method of this site.
People bounce because they wanted a product name. Product names go stale, get recalled, and fail to fit a particular bench. Official sentences last longer. Transport for NSW, Transport Victoria, Queensland TMR, the other road agencies, CREP, Kidsafe and the ACCC already wrote the sentences that matter. Our job is to put them in an order a tired adult can follow, and to refuse the extra sentences that would make this domain look like a shop.
If you are choosing a seat, the order is mark, stage, vehicle, optional CREP, recall search, fitter. If you are using a seat, the order is book, mode, tether, harness, fitter. If you are travelling, the order is the state you will stand in, the vehicle you will actually occupy, and a plan that does not involve sharing a belt.
Stay on the page until you can say those orders out loud. Then leave and do the physical thing. A hub that only produces more tabs has failed.
Related reading sits at the bottom of the template on purpose. Use it. Internal links are how a rebuilt heritage domain keeps old backlinks honest.

One more pass for readers who stayed
If you are still on this page, you are the reader this rebuild was for. Close the marketplace tab. Open the agency tab. Look at the seat in the room. If the mark is missing, stop. If the markers say the child still fits, stay. If the install has not been seen by an authorised fitter, book one. If you are driving in another state tomorrow, open that state page tonight.
The Australian conversation is unusually consistent once you ignore shops. Birth to six months is rearward. Six months to four years is rearward or a harness. Four to seven is a harness or a booster. After seven a belt is legal when it fits. CREP and Kidsafe keep telling you to wait. The ACCC keeps telling you to search recalls. None of those institutions asked this domain to invent a ranking.
Use the related links. Use the resources list. Use contact only if our wording is wrong or a source link has moved. Then go do the physical job. That is the end of the page on purpose.
