With regard to Australia i do know a bit about the situation there as my xMil lives there and is an Australian citizen, we visited a lot and when FIL was due to retire an offer was made to us, they would gift the house they were living in,5 bedroom bungalow to us and X would take over the Singer sewing machine centre which FIL owned, it was a successful business and X had a similar business in the UK. We applied to emigrate, and were immediately turned down,me, too old at 35, X did not have a formal college qualification accepted by the Oz authorities, he is South African with british parents and a british passport, the only member of the family who would be accepted was Autistic DS1 who was studying Theology at the time. I have a very good uni degree and a diploma in Community Education, and was working in that field at the time. The business closed, 4 part-time staff losing their jobs.
XMIL worked for the local council and arranged an appeal for us, we were told the business was not a necessary one and there were no suitable jobs for me in the area.
Canada is not the land of milk and honey as friends of mine from Toronto would be very happy to tell you. Anyway you need visas etc to work in these countries, you cannot just arrive in them and get a job the way you can in the EU. The situation is completely different and cannot be compared. Oh and Xmil gets her state UK pension every month although she left the uk in 1955 and is an Australian citizen. Perhaps you can explain that one????
