What are some AUD dollar Investments that I can look at in 2020?

Hey there Mr Wu! You could consider Auzzie denominated funds. I recently went into JP Morgan Global Income Fund - Bloomberg ticker (JPMGIAA.LX). The yield is approximately 6%, pays out dividends on a monthly basis, really good for passive income! But do do your due diligence should you decide to buy into it. I believe some banks do offer the fund. Just that there are initial charges involved and it'll take a couple of months to recoup them

Change them to SGD or USD. AUD is weakening and you will need to achieve a higher expected return to reduce the loss/risks from FX.

even if you frequent Aus, it will be better to change them at a better rates as it seems that AUD is struggling to hold at it's current pricing​​​
