What's you expectation on your investment.
Are you after capital growth or dividend yield.
Aussie companies are good yield payers in general, a lot of US and International shares are generally low yield but higher capital growth due to the fact they are generally looking at the world as their market so have a lot more options to reinvest earnings within the company rather than pay high dividends to shareholders.
Another option could be to use some of the ASX listed ETFs that invest overseas. ishares have their global 100 and consumer stables ETFs which provide access to a large number of high moat companies. The yield is low at < 3% pre tax, but you would expect over a few years to generate some decent capital growth.
I put some money internationally simply as a hedge should the aussie economy stumble late this year or early next year and takes the AUD with it.
