Stayed in Isa over the rodeo weekend at a lovely caravan park just on the edge of town - Moondarra. Our room was only $90 a night, which is very cheap for Mt Isa we thought. We had a little room which was a specially made caravan but more like a small motel room, all very new and spotlessly clean. There was a kitchenette with tea and coffee making and a microwave. we cooked a BBQ in the camp kitchen overlooking the river - lots of birds to see.
Management were friendly and told us what was in the area to do. We caught a free bus into the Buffs club one night, and ate at the restaurant at the park another night. The food was very good. Would recommend.
