Mary Kathleen was an overnight bush camp near Mt Isa. According to The Sydney Morning Herald: This famous mining town has been reduced to a bitumen road leading into the bush about 55 km from Mt Isa and 62 km from Cloncurry. The site is not marked but is on the northern side of the road. All that is left of the once thriving town is a series of old streets. Everything else, including all the houses, has disappeared as the centre was completely closed down.
