How can I transfer Ping balance to Australian Bank? I am an Australian seller.

Hi 

How can I transfer Ping balance to an Australian Bank? I am an Australian seller. I can use my AU credit card to deposit the listing fee to Ping account, but how about withdrawal? 

Also, how can I add a tracking number to the order if I use my own parcel service? Now I am using email to send the tracking number to the buyer. 

Thanks.
