Accommodation in Canberra during Summernats

[BAFalconXT]

I know there might not be much accommodation left near exhibition park... I have done searches on the net, there wasnt really much I could find. Where are other people staying? Anyone in Canberra know the names of cheap motels/caravan parks with cabins near there? I dont feel like sleeping in a tent. Within walking distance would be good, so I can get ****ed everyday... Any help would be good!
