DirtWorks have got a heap of stuff on sale, in particular a heap of wheelsets for 40% and 50% off. Someone put up a post about e13 tyres, but the sale covers a lot of other stuff.
I'm pretty sure these guys are the importer, although I could be wrong about that.
Anyway, there's some really sharp pricing on a bunch of wheelsets, with heaps of choices of driver, wheel diameter and rim width. Only problem is they don't seem to have any mixed wheelsets, but maybe you could contact them directly and work something out.
Highlights are probably this carbon wheelset for $1200 https://www.dirtworksb2b.com.au/wheelset-e-spec-race-carbon-… or the LG1 downhill wheelset for $640 https://www.dirtworksb2b.com.au/wheelset-lg1-plus-downhill-2… but there's a heap of options.
Sale ends at the end of March.
That's a cracking deal for a quality carbon wheelset! Upvote for OP
