If everything is trackable, does that mean everything gets PayPal Seller Protection? If so, that sounds worth the price hike to me. At the end of the day, all Aussie sellers are in the same boat re: price rise, so it will even out eventually.

Just reading some of the pdf files on the AusPost website and the new 500g parcels (lodged at AP) are $6.95 including tracking, which seems like a good price. I'd probably be tempted to add the Signature on Delivery though for the more pricey things.
