The downloaded standalone products in the Australian store manage to avoid GST, presumably because they are downloading from the overseas servers. ( I can't see why if it's coming from US servers, they can avoid paying GST but still charge us a massive premium on the US price on downloaded products, but that's another issue!) .
I would thus have expected the creative cloud subscription to not attract GST as it's a download - So I would expect to be charged $62.99 . But Adobe's Australian pricing is weird and wonderful so who knows? (eg the upgrade price for standalone Illustrator CS6 has gone up substantially and is close to double the US price, while the photoshop CS6 upgrade has about the same price differential relative to the US that CS5 did)
