Are those all Australian based companies? I have some German companies in my portfolio because I don't pay an extra tax on the dividends from them. Does something similar exist in Australia?
I have my passive income-investments split 3 ways at the moment.
40% in local cooperativas/saving banks, making between 9 and 12% interest per year (as secure as a cooperativa in Ecuador can be...)
30% in the construction firm of a friend, paying me 20% per year.
30% in stocks in Germany, mostly growth and/or value, very little dividend until now.
I don't count the bakery as a passive income yet, since I'm still actively involved and doing quite a few things, though I wouldn't have to. If I counted it, that would be 50% of my investment, and the rest would be 20/15/15; and the interest is between 20 and 25% (that's the net profit margin).
Years ago, I calculated the minimum I would need to survive (no luxuries at all, not even beer) and keep Lily in school, insurance, and all she needs. That was $600 passive income, and I reached that a couple of years ago - not counting the bakery.
The stocks in Germany are saving up for Lily to be able to study there if she decides to do so. When I studied, it costs my mom around 25k over a lapse of 4 years, and costs have gone up a lot since then. I think I'll need at least 70k, due in around 12 years. A long way to go still, but I'm confident that my strategy will pan out that way - and maybe in 12 years my bigger holdings will pay nice dividends, so I don't even have to sell stocks.
So far my financial plan which is working out really good. During this crisis, it was the first time that I did not worry about money at all. I up fronted wages, helped with loans, and yet not once was I scared that I might not have enough. That felt really good.
