Don't despair. It's very normal to go thru the homesick stage. We once left South America for Europe and eventually moved to Canada. Now we are looking at spending more time in Mexico, probably months at the time. Why Mexico for us? Well, it has one of the best climats in the world. Close enough to Canada to visit the kids and grandkids. You must try to find a place or organization where you can meet fellow emigrants. Not nessecarily from Australia. I promise , it will get better as you get established. Mexico is a wonderful country. The people are friendly, and it has a lot of history. Mexico city might not have been my first choice. I would prefer more towards Guadalajara, Chapala, etc. However, I am sure that there are wonderful areas around mexico city as well. We considered Australia as well, but it's too expensive, another big city (like Vancouver), and too far for us. This is just our opinion. In the meantime , stay in touch with others. If you so wish, you can email us at anytime and we'll reply.
