glen, the address given by the PayPal payment is the only address covered by PayPal's seller protection.

so, if you are using a trackable postage method is needs to go to the Paypal supplied address.

I 'm in Melb but often buy and have shipped to son and dil in Sydney, nothing unusual about that, I, the buyer, chooses the shipping address in checkout before paying with paypal, it can be any address I choose, not my eBay registerd address.
