Interesting article I read in B&CA many years ago, stating that some of the worst icing conditions in the World can be found in South-Eastern Australia, very moist South-Westerly airflows with conditions just below freezing leading to extreme icing conditions... I remember one night flight in an Air Ambulance Queenair going into Cooma,this was with hot-props boots and all, Max Continuous Power with about 110 kts IAS and barely maintaining altitude, after landing digging out many, many Kgs of impacted ice from the intakes, as an aside another article on Thunderstorms stated that the Brisbane-Gayndah corridor contained some of the most severe CBs to be found anywhere...been there too...
