You have a more serious issue than tracking numbers and waiting time.
The risk with buying anything electronic/electrical from China is that the components used in Chinese factories (not made for a major brand with quality control) are the cheapest possible, and very frequently do not meet the product specifications. WIth electronic items the risk is huge. The raw materials of which such items are used need to be very specific, as if a lesser material is used, it won't be sufficient for the demands of the product.
It's not just that such items are likely not to work as stated (or not last if they do work, or not work to the full specs) - but - the really bad risks are the item exploding, bursting into flame, destroying the phone when you plug it in, destroying more (possibly your house), and even causing injury or death.
No insurance will cover any sort of damage caused by using an electronic/electric item that doesn't meet Australian standards. It's not a risk I would take...
Now, in terms of waiting for months - NEVER allow a seller to string you along for months without delivery.
You have 30 days from the latest "estimated delivery date" to report in My eBay that you haven't received the item. You've said that it's been 59 days since you placed the order, but if the delivery time was estimated to be quite long, it's just possible that you may be still be within the eBay Money Back Guarantee timeframe. You won't lose anything by trying, at any rate.
This is the link to Get help with an item that hasn't arrived (in other words, open a report/dispute). You should see the items that you've purchased recently; click onto the item that you didn't receive, and follow the prompts. (Ask here if you're not sure.) If you're still within the timeframe, you'll be able to open a claim.
If, however, the latest "estimated delivery date" for your purchase is more than 30 days ago, you'll need to open a PayPal claim.
Go to the PayPal Resolution Centre, log in, click onto the blue button that says "Report a problem", and you'll see a list of your most recent transactions. The page will be headed "Report an issue by selecting a transaction", and that's exactly what you'll do. Just click the selection button next to the relevant transaction, and it will clearly show the seller, the item/s purchased, the item number, and any tracking details. If there is a tracking number, double-check it to see if there's any tracking information.
Then click onto the blue "Continue" button at the bottom of the screen to go ahead and report that your item hasn't arrived. It should be straightforward from there.
Be careful to escalate the dispute to a claim NO LATER than 20 days after you open the PayPal dispute. You must do this, otherwise the dispute will automatically close and you won't be able to re-open it.
Make sure that you reply within the PayPal dispute if the seller responds, and if you're not certain about how to respond, post here again as there are a number of very knowledgeable responders who can advise.
