As for foreign markets, don't go there yet. You need more money to make it worthwhile due to higher brokerage, and there is also more inherant risk due to exchange rates. So while your shares might go up 10%, if the exchange rate moves unfavourably by 10%, you've gained nothing.
Your approach may work, I'd suggest looking at the dividend yield as well. 'Theory' says that the dividend is the sole thing used to price shares.
If a share's dividend yield is only 2%, then even though it might go up, and be going up already, there are probably better opportunities.
For example, and I do own these so take my advice with a grain of salt, zinifex currently has an upcoming dividend which will be around 4% yield. You can also claim imputation credits in your tax return, as this has already been taxed at 30%. This dividend is only for half of the year, of you hold them for the full year, you are likely to get 8%+ easily in dividends alone. So look at the capital gain you expect, I'm not going to speculate here on how much that might be, but you see what I mean. Gaining 8% in dividends leaves a lot of 'safety' for the price going down a bit.
The banks all have a half decent dividend yield which is around 5% p.a. as well as good capital gains. So these could be called nearly as safe as a bank account, and 10-15% annual return overall.
