Fe: Difficult. You’d have to use P-Clamps and the brake hole, ok, but not for significant loads. Otherwise you could use a rack with axle supports, which will either be cheap and nasty (Wald, not that nasty, but I don’t think you can get them in Oz?), or heavy duty and pricey (Paul Flatbed)
Al: Brazeons behind the axle are for fenders, the fork blades will interfere with the rack legs unless you do some judicious spacing/bending. But you have mounts on the legs so you could mount a lowrider rack? Abbotsford also have a nice little Minoura rack that mounts on the brake bosses and comes in black/white/red/blue. It’s designed to work with cantis, but may work with Vees.
Sexy racks: ANT, Tubus, Jim Blackburn, Cetma, Ahearne
Keep in mind that high trail = bad loaded handling. I try not to put too much on my front rack, it really throws the handling out. (Especially when I put a spring-loaded collapsible basket on the LHS and loaded it up asymmetrically!)
I scored an old Al Jim Blackburn front rack that mounts on brazeons & brake hole from Human Powered, but you have to be quick, they get snapped up in a flash.

I’m wrong, it doesn’t use the axle, it uses brazeons, but comes with spacers to work with the ones behind the dropouts.

If you have some tubing and a MAPP torch you could probably homebrew your own copy of a CETMA.
