Be aware that some are oil cloth, some are waxed. Never had an Australian, but have worn Barbour and Filson for a number of years. Have a no name (that I remember) oiled one, great water repellent, left stains on my cloth seats and any papers that touch it. Comfortable other than the sleeves need to be longer and the hood is too small. Filsons are tough but crude compared to Barbour. Both Filson and Barbour weigh a ton, and if you are in a heavy rain/drizzle for a long period, they all eventually seem to leave you damp. Religious following of a re-treatment regimen will minimize it but if it's an active sport you are involved in, expect stress points to get damp. (top of your shoulders and elbows) Never had a Filson that didnt shrink with age when cycled through repeated rainstorms. Havent noticed shrinking in Barbour.
I get moisture build up in anything that is waterproof if I am active, waxed or oiled is no different. Goretex and Event are pretty similar, Sympatex is more waterproof but I really sweat in them.
