I understand the frustration, and agree with Marina's post, but there are some things you might want to consider which could help prevent this from happening again (if the winning bidder doesn't pay and you decide to relist it after the dispute process has been resolved). Hopefull some of it will be useful. ๐
As the console and included accessories have a pretty fixed RRP and they're relatively readily available, and since you listed with PayPal only, you may want to consider listing as a Buy It Now with immediate payment required, as that will prevent anyone from going through with the purchase unless they pay for it straight away. You would of course have to decide on a fixed price, though.
Another issue is postage, but you can (and probably should, either way), use the calculated postage option rather than flat rate. If you enter the package dimensions and weight, the postage displayed and charged will vary based on the buyer's location (it uses Australia Post's pricing), so you wouldn't have to worry about under or overcharging on postage whether you used instant payment or not. You can also add in an amount for a handling charge (done separately but included in the total P&H), so if you need to add extra for packaging materials, signature on delivery and insurance (strongly recommended due to the item's value, whether the buyer wants / pays for it or not), you can do it there.
The only major issue with listing it that way is that you will allow pick-up. That in itself is not an issue, but accepting PayPal for a pick-up item can be. (There is no PayPal buyer or seller protection for pick up items, and immediate payment will only work if PP is the only payment option offered, so that exposes you to a potential risk).
