Hostel World - Website
Many of you may already have visited this website in your trip planning process. Since I just discovered it I’m going to post it anyways. First of all this has pretty much the best hostels from all over the world (not just Australia) along with reviews and ratings. You can book through the site as well.
The extras on the site are what made me check out the site longer. I started listening to some of the podcasts, downloading pocket guides and even checking out the route planner. Of course you need to create a free account so you can access some of the content but it seems like a good site for travel planning. I think I may return to it when I need a hostel on short notice.
