Thanks to some tip offs in the Online Sightings topic, the Ravage 2-pack is finally being offered to Australians by two Australia/New Zealand sources...
MightyApe (in New Zealand, but ships to Australia and NZ) - $91 (shipping from $5.90 = $97) (extra for express shipping)
Popcultcha (in Victoria, ships Australia-wide) - $90 (shipping $9 = $99) (they offer free shipping on orders over $100, but apparently limit this item to just 1, which doesn't qualify)
The release date is noted at November 30th on one site, which probably applies to both, so expect it to be delivered within the first week of December from either source.... but be aware that there may be shipping delays at this time that might add a few extra days to the estimate.
I was expecting it to show up at EBGames/Zing, but they haven't listed it yet. If they are still getting it, they may list it when it arrives if they aren't getting too many units.
If they also get it, or it shows up at another non-import source, I'll update with details... but for now, there are two pre-order options for those who don't want to risk missing out (provided they don't over-sell and have to cancel orders later).
