You knew the total cost of the items and postage before you bought them, and presumably that price was acceptable to you or you wouldn't have gone ahead. So what is unfair?

The fact that you have been charged postage in US$ and Euros indicates that you have bought the wigs in both currencies.  The seller has no option but to send invoices in both currencies.

If the postage was reasonable on each separate package you have no cause for complaint.

The seller has made a mistake in sending them all in one parcel but it is hardly earth shattering and surely more convenient for you to get one parcel instead of two.

This is what is wrong with ebay you buy you pay then after you get items do you wont to winge and moan about  prices being too dear or postage too expensive why did you bid and buy it if you dont like the price go elsewhere and dont whinge about it sick hearing about it.No body forces you to bid or buy

490 CNY = 83.25 AUD

You've paid $AU 6.48 handling for each item.

Sellers are allowed to include packaging and handling in their postage price, the postage price isn't necessarily just what it costs to post.

Did the seller send the items by the method that they stated in their listing?

They would have had no choice but to invoice you seperately because of the two different currecies.

I don't know if there would have been a difference in price had the parcels been shipped seperately, but remember that a seller is not obliged to ship the parcel by the cheapest method or to discount postage. Combined postage does not mean discounted postage.

Were you aware of the postage costs and handling charges before you committed to buy? (I think you may have been)

However, I do believe that you may have recourse, but as you knew the postage and handling costs before committing to buy and you did receive everything that you purchased, assuming the seller sent the items in the method that they informed you then, those avenues would, in my opinion, be unethical.

I have purchased 18 wigs from a seller who split the order into 2 separate orders then charged me postage $78 U.S for 10 wigs and $74 Euro for the last 8. I then receive all 18 wigs in one parcel from Beijing china with the seller being charged 490.00 yuan postage.I have requested refund of some of my money but the seller is saying that I am cheating them. All up I have paid $199.91 Aud for postage of a bag weighing in at 2902 grams.

Two invoices =  two payments = two parcels

Paypal rules = two separate payments = two separate proof of post evidence  

IMO, two separate payments for goods sent in one parcel, not sent in accordance with paypal policy = possible partial refund - potentially achieveable by just opening a paypal dispute - and getting more appropriate seller response.
