I thought the same when i was looking for HQ Van.. every van didn't matter what it was HQ-WB were all everywhere else except NSW!
I had my mind set on a HQ van.. but i would of settled if i was able to track down a HQ chassis and get a HJ-WB van body to wack on it.. HQ chassis cause you can put a 350 in it or even a BBC without any problems.
I stumbled across the White van on Ebay when i was on holidays I had to have it..
it was in Sydney and was owned by b-rock-05

Then we found the Blue Windowless HQ on the bay as well.. but it was in Echuca we just had to have it as well.. was too good not to let go so we made a 3 day trip to Echuca to get it.
