Anecdotally eBay.com is as full of Chinese[correct spelling] bleep as well.

And buying from America has its own pitfalls. Like currency conversion fees and the GSP.

If you buy the sort of stuff that Chinese sellers supply, you're probably better off buying from a real shop. Where your Chinese junk will come with a warranty, if applicable.

Hint: Don't buy anything from Apple; all their stuff is made in China these days.

Be aware too, that there's a high probability that the phone you bought is a fake. It may not comply with Australian standards, and could only work for a few months before dying. I'm sure they promised a warranty, but it is impossible to claim on it. Be careful with your new phone.

Free postage has no bearing on whether there is a tracking number....someone has to pay the postage so there should be a tracking number.

I have reported a number of items with false location , description or are fakes and ebay does nothing.

Nearly all the negs you've left are for sellers registered in China, perhaps it's past the time that you should be checking feedback for the seller's registration location, and be wary of any high-volume sellers with less than 99.5% feedback rating.

Unfortunately Chines sellers tend to be a protected species on eBay.

Australia Post's Sydney parcels bulk lodgement centre is in Chullora and where most Chinese drop shippers and consolidaters deposit parcels into the postal network.  The locality is home to many logistics companies.  The other common location is Botany and as soon as you see these suburbs you know your item has been shipped from China.

Botany is almost exclusively logistics companies who import the goods and hold them in storage and then disatch the individual parcels to Australian addresses when told to.
