scotbill - Australian ATC have used grouped callsigns for while. Can cause problems of its own eg 'Qantas five eighty' and 'Qantas five eighty two' are easier to confuse then 'Qantas five eight zero' and 'Qantas five eight two'.
Then there are oddities like 'Qantas seven sixty seven", which is usually but not always a B767, 'Virgin seven forty seven' which isn't a B747 etc. I shudder to think what our US cousins would make of 'Qantas nine eleven"!
