I just bought this, meant to be a really good collection. Can't seem to find it at many places apart from eBay (a lot of the cheap ones don't ship to Aus) and Amazon ($290 + shipping). The DVD version retails for $450 at JB Hifi Online.
These were the shipping details I got in the email:
Estimated Ship Date: August 9, 2013 to August 19, 2013
Estimated Delivery: August 21, 2013 to September 12, 2013
Expires in 14hrs. AC/DC and The Who specials are on the next 2 days.
The Blu-rays are region free as stated here: http://www.neilyoungarchives.com/NYAFAQ.html#tech
