Hey,

Have you thought about coming down yonder way? There's some awesome mtn biking on the North & South islands in New Zealand.

How long would your vacation be? If it's only 2 weeks, venturing down here to aust/nz would be a bummer as you wouldn't see tons. However, in saying that you'd could base yourself somewhere like Taupo(north island) & do rides in that area. Otherwise, you could do the queen charlotte track on the south island...

If you plan on Australia-why not do Tassie (tasmania) as you can hike & bike in a really really nice place!!!! This is if you don't mind mountains...

Now, if you want to do Canada...Why not look at www.intrepidtravel.com.au-they have some awesome tours...!!!!(small groups-max 10-12 folks)

Why not do Alberta, Saskatchewan, Manitoba-basically acrross the praries, tons of history,scenic & booooooteaful..

Many thoughts
