When it comes to repeat business, Viennese optometrist Alfred Pruckner must be a dream come true for the local tourist industry. Since 1995 he has toured Central Australia 16 times, every time staying for a few weeks, cruising around the bush in big hired 4WDs, taking in the well known attractions, and many not so well known. His experiences over nearly two decades make him more qualified than most to judge the region, from the standpoint of a paying tourist. ERWIN CHLANDA reports. PICTURED: Alfred and his partner, Erika, at Chambers Pillar and this week.
