If you come to rent for a few months during the off season (June till mid Sept is the best) you will be able to find a place to rent for the lest expensive price. 400 to 600 U.S. dollars. I do recommend that. Renting in Riberas or Chapala or San Antonio Tylajacapan would be central to the bus line if you are with out a car. I travel to the land down under every few years and yes the prices are a bit high. I shop for the least expensive to LAX then search a Mexican airline to Guadalajara to get the best price. Just did a search for June 1 to Sept 1 2017 on Interjet and the price was 309 U.S. dollars round trip which includes two 55 pound suitcases for free. There is also Areo linea airlines to check out. I have found prices on the flight from Oz to Lax for anywhere from 800 to 1200 U.S. and missed one deal at 600 Round trip U.S. This is a great place to retire, I have been here for almost 20 years now and still love it. I have great friends from the U.S. Canada and England and my dear Mexican friends so it is quite a mix you can chose from. Every time I go to Oz I nearly have a stroke at the prices so I am sure your Aussie dollar will get you a great life here. Let me know when you plan on being here (dates and if I am here at the same time) I will pick you up at the airport in Guad and shout you a stubbie! The Aussies are the greatest and have been so nice to me when I am there I will do my best to help you out while you are here. Pm me and if you have skype we can talk and I will try to answer any other questions you might have.
