We did option b just this year
The biggest issues have been work situation & medical care. Medical care is way better than we got in Sydney but it's different & I find it hard to get used to.
Work sucks, opportunities & work ethic/safety terrible up here especially for DH. Be prepared with a few months money behind you as jobs can be scarce in smaller towns.
Other than that we ❤️ it and it's given us a great quality of living & wonderful lifestyle for kids. We have found it hard to click with people so don't socialise with anyone new, however truth is we aren't overly sociable people anyway lol
