It Makes Sense to Buy Australian Gold Coins

My wife and I have been living in Sydney for the past fifteen years.  We both work from home, running a successful website that we started five years ago.  I know everybody doesn’t find online success and I am very grateful that we have.  We are making good profits and saving as much money for the future as we can.  We have been taking part of our money each month and using it to buy Australian gold coins.  I like to diversify our investments a little bit and this makes perfect sense.  I want to make sure we have plenty of money when we retire.
