Yes I am an Aussie, and yes I require a callsign when recieving a readback. If some here think that is anal, then so be it, I am anal. I call it safe. If Aussies have the reputation for being in your words anal, in my words safe, then I am proud to be Aussie. We now have every night a rush of 20 QTR flights all Eastbound with as many as 10 on one frequency at one time with all very similair callsigns, and with an amazing propensity to answer each others calls. Frequency transfers are bad enough, and do take up a lot of time locating the aircraft and getting them back with who they should be, or just confirming the correct aircraft did change, but sometimes you have QTR aircraft taking company traffics descent and turn instructions with no callsign. Again if I am anal for not just sitting back and accepting that sort of airmanship, then so be it.
