As you will all be aware, there is a huge range of accommodation in Coffs Harbour. For those who do not have relatives in town who you can stay with, I suggest you go to the Coffs Harbour Tourist Information site at and click on Accommodation, then Search Accommodation. This will take you to the wotif link and there are many options available.
For those who wish to bring a caravan, I usually stay at the North Coast Holiday Park (At the Showground) 123 Pacific Highway, Coffs Harbour NSW 2450 Ph: 02 6652 1694. This is handy to town, has excellent amenities, no pool or jumping pillow, but on the highway and can be a bit noisy. There are other parks which you will find through Google.
