Great place Wilcannia, recently spend 3 days there at Warrawong park and loved it, one of the best parks I have stayed in, also try the coffee shop in town and if your after fuel go to the other garage on the back street, it was 11 cents cheaper a litre than the one on the main road for Petrol and Diesel.
Wilcannia used to have a bad reputation years ago but thats gone now
