You have many possibilities, but if I were you I would decide what my heart wants, even if it would be a more complicated process or lasting longer to get PR etc.
Where do you, deep inside yourself, think you'll feel home, satisfied, happy to be?
Choose that country!
If you are family bound, why not considering Australia?
A door will always open, if you believe in your dreams.
Have you already been in Australia, NZ or Canada?
My place will be Canada, but I prefer a colder climate, lots of snow and rural communities - first I thought it will be either BC or Yukon, now it seems to be the Yukon, as my hubby received a job offer in Whitehorse - like mentioned before, a door opened.
Wish you all the best I am sure you'll find the appopriate route to make your dream come true.
