There aren't many things you can see near Purrth that you can't see anywhere else in the world (and probably somewhere closer to you). One exception is that you can see some of the most incredible wildflowers you've ever imagined here. If you're interested in botany or gardening and you get the chance to visit Western Australia, time your trip for late August to early October to see all this lot and more.
Here are a few photos taken on a day trip to New Norcia, to the north of Purrth. Some of the shots that don't suck too badly are links to a bigger version - those are between 100 and 150Kb in size.
Unlike me, these folks know what they're talking about:
