I would inquire as to travel of this beer, before purchase. Ask if it's made it way down here (AUS/NZ) by way of Europe, first. If so, it's gray beer and I can almost bet quality has been compromised, as compared to what you would've enjoyed in NY, etc.
If you really wanted it, and are prepared to cough up the dough, I would contact the brewery directly, pre-pay for a slab, have them pack it properly at refrigeration temps, then priority express it here. Or if you have a contact in the States, have them grab a 6 and do the same. Even if you skip the packing at cool temps (to save weight/cost)- have them purchase the 6 at room temp, package and post straight away. Unless it's ridiculously disturbed in transit, it should be far superior to what you can buy locally. Make sure they shop around, and grab the freshest (by manufacture date) avail, too.
