Having spent 90% of my flying career in the sub-tropics/tropics, I know all about flying in icing conditions! Yeah right!
I aversion to ice is right up there with my aversion to CBs.
Here's my approach for a GA aircraft not approved for flight into know icing conditions.
1) No flight in sustained cloud at or above the forcast freezing level.
2) If flying in IMC and icing occurs - immediate 180o turn and bug outta there. There was no icing in the air you just flew through so there should be no icing when you go back there.
3) Descend into warmer air if LSA allows, before returning to the desired course.
4) Take a different course that has a lower LSA - well below the freezing level
5) If in doubt - head for the nearest instrument approach behind your present position, with the lowest LSAs and land.
Nothing is so important that you should risk smacking in!

PS: I suspect that people who operate in southern Australia are considerably less averse than I am!
