This is a pretty interesting topic. Here's a few of my thoughts on the matter.
Here in good old Australia (a place that President Bush recently renamed Austria, while he was actually here in Sydney) we're like Canada. We, too, have got Queen Liz II, a GG and a PM. We have also got lots and lots of open space, and you can spend weeks in the National Parks without ever seeing a ranger, or anyone else for that matter. That's the good bit.
What's not so good is that our gear manufacturers and retailers are still largely stuck in the era of heavy, bombproof, indestructable gear for which they charge massively inflated prices. When asked about lighweight gear the response is usually along the lines of "we need tough (aka: heavy) gear for Aussie conditions". Which, of course, is crap.
Anything that is imported is even more expensive (except if it's from Asia).
For example, local retailer, "Paddy Palin" charge US$563.00 for a Western Mountaineering Summerlite s/bag. That's a massive US$273 mark up from what I can buy it for from US companies like Bent Gate or Backcountry Gear($290). It's blatent profiteering and given that they are the only local importer of WM, if you want one you gotta pay.
The result of this is that I buy nearly all my gear from the US, via the WWW. I have never had any trouble. I have often encountered companies that do not service the international market, but I have always been able to buy the same product from another company that will.
Companies I have dealt with include: Backcountry Gear, Bent Gate, TarpTent and BPL. I have bought stoves off Tinny from Mini Bull Designs and a pack from zpack.com – all of which arrived safely and promptly. I can recommend them to my fellow Aussies and anyone else for that matter.
