I checked the wiki and searched the forums but didn't see an answer to this question, although it did come up in regards to the USB charger issue a little while back.
Certain devices are not legal for import into Australia or to be sold because they are not certified. The name given to these devices in the laws is prescribed/declared/proclaimed articles, and the government decides which types of devices should be on the list. For example, electric kettles are on the list. No uncertified electric kettle can be sold, but the actual laws regarding such prescribed articles is up to the states. Other articles include chargers, microwaves, electric blankets, etc. A full list is available here: http://www.esv.vic.gov.au/Electricity-Professionals/Electric…
However, each state makes the laws on enforcement, so although it seems like WA says it's illegal to use these devices, QLD was less rigorous in the area so does not seem to have a specific law against privately buying it from Gearbest and then using it there.
Every single state has come out on their gov websites and suggested that nobody should be buying these types of products. Insurers refuse to payout because these products are uncertified. They can all cause fires if they are badly made. Certification can ensure that the products are safe, so all declared articles must be certified if they are to be sold in Australia.
So my question is, should we have these types of uncertified, quasi legal bargains listed on OzBargain? Should we report these bargains because it's not a bargain to have unsafe electrical equipment in our homes? Or should we just let people do their own research and buy them if they like?
In particular, this kettle: www.ozbargain.com.au/node/277311
You'd be surprised at how many uncertified products are in peoples houses. Some stores like Jaycar sell devices that haven't been properly certified.
I personally use Xiaomi power strips which aren't AU certified. I have them disconnected when not in use to be safe.
