I'll pre-empt Alan Hyatt here............
The Aust., market is NOT substantial enough for SP to invest in that kind of business structure, although I think by now Alan is well aware of the anomalies in pricing structures, and having an idea of his business philosophies, I would guess that as he is able, (i.e; as he gets time between other aspects of business), he may look into this issue.
There is apparently a "rough" formula that importers within the music industry here in Aust., apply to imported goods when determining the pricing structures. From memory, I think you can easily apply mark-ups in the region of 150%-200% and often more. They do deviate from this on occasion, but only when it will benefit their profits or when they may sacrifice the margins on one product from a range to act as a sweetener or bait.
As an example;
Fostex D160 H/disk recorders had a RRP of over $6000 Aust., when they were a current model, with an expected sale/street price of around $4800-5000 Aust. When the new D1624 was being released, the importer reduced the D160 pricing to the extent that the dealers' (music stores') cost was approx., $2200 Aust., which means that the importer was paying less than that again. Also, the importers will frequently insist that only they and not the overseas suppliers can set the pricing for Aust.
At first glance it appears that the importers of the MXL mics are sticking to the accepted industry habits.
Obviously RODE have realised that they have to change their Aust., pricing structures, although I imagine they will only do the bare minimum necessary.
