I was able to online-order a box of 25 sets of DÁddario Super Light strings from Stewmac, but they'll take anything up to 4-weeks to arrive in the post, so, no more guitar-playing till then for me.
There are plenty of online retailers in AUS that sell D'Adarrio's in bulk. Not sure why you went overseas. With the current condition of the AUD/USD and shipping, the domestic prices are pretty reasonable (from the right seller).

Also, it would take a whole lot more than dead strings to keep me from playing!
