You won't be much over Aus$1000 per set landed in Aus
(maybe just over Aus$1100, depending on what model).So if we take the B6 Front Left as an example. It is VE3-B830.
Bilstein Germany lists prices online. They charge 227.00 EUR ea, which is Aus$352.75. (But expect to pay a LOT more from Bilstein Aus).
They actually list what OEM Subaru Parts#s each model corresponds to, but none match the 20310AG433 Subaru Part# that our stock billies are. But B8s are not listed as having OEM Part#s, so the chances are good that the factory Billies are basically B6s.
http://www.spring-loaded.co.uk in the UK list them at £184.26, which is Aus$369.76
http://www.partsgeek.com is great (that's where I bought my set of 4 Billies for the Merc). They are US$214.23, which is Aus$297.08.
EDIT: Partsgeek list 2 different B6s (HD and Performance). Price above is HD, Performance are US$231.33, which is Aus$320.43. That's confusing, I don't know what the difference is.
And rears you're looking at US$102.23, which is Aus$141.60 (B6 HDs and Performance are basically the same price for the rears).
Years ago I paid US$200 for freight from PartsGeek for 4 Shocks. Since weight counts most, that gives you a rough idea of what 2 shocks would be if you only get 2 (~$100).
