My knowledge of accommodation options in Canberra is limited, so I’m hoping that people will share their experience in comments, but here are a few possibilities.
If you want to be near the University of Canberra, then your best option is probably the Belconnen Premier Inn which is within walking distance of the campus. According to Wotif, there are twin rooms available on 6, 7 & 8 October for $153 a night. This includes a whopping 100mb of free data via wired broadband (don’t go crazy people!).
Alternatively you could stay somewhere near the centre of town (known as Civic) and catch a bus out to the University of Canberra. Amongst the more reasonably priced options close to Civic are the Canberra Rex Hotel and Olims Hotel. They’re both about 1km away from the city centre. On Wotif, the Rex has rooms for $149 on 6, 7 & 8 October.
The Canberra City YHA is right in Civic and has beds available in their 4-share dormitories for $39 a night.
Any more suggestions?
