Hey Coachky
DW and I are also working in the UAE enjoying tax free USD and I presume from your intro you are also not a tax resident of Australia.
I do not know all the correct answers to your questions, but will tell you what I do....and because your questions are directly relevant to me I welcome advice and corrections from the clever peeps on this thread.
We invest in a mix of VAS, VWRD and VDEM. We have own some property in Oz that is leveraged to a point that, with depreciation deductions, we don't pay tax. We also have a decent amount in super back in Oz, but are not adding to the stash.
We are not adding to super as we want a stash outside of super to fund our FIRE. We will FIRE when I am 46-47 and DW 40-41, so a long time till we can access super.
We are investing in international and emerging markets (in USD) because I know we will spend plenty of time (years most likely) outide Australia over the remainder of our life so having exposure to different currencies and markets works for us.
I also am a bit bullish on emerging markets.... but that is just a personal bet, not a recommendation.
I don't know if you saw Bill Evan (WBC) comments this week forecasting the AUD to continue to drop v the USD over the coming year. He was predicting 65c. If this happens it'll be a huge bonanza for us getting paid in USD and shipping cash back to Oz.
For VAS, as non-Oz tax residents we have to pay tax on un-franked dividends. No tax on franked dividends. Tax on unfranked dividends can be offset against tax losses on negatively geared property (confirmation from others please :-) )
My understanding is that generally we won't be liable for CGT on selling VAS, except for any portion that relates to a sale of shares of Taxable Australian Property.... this part is a bit unclear for me so again I would value the knowledge of others..., we are not selling now just accumulating so this hasn't been an issue thus far. I figure any CGT will be quite insignificant.
For my part, I would be interested to hear the thoughts of others on investing in super as a non-tax resident. It seems to me that getting money into super is a good idea, but an even better idea if I wait until I get back to Australia and can benefit from some tax breaks by loading up my super then. I am thinking while out of Australia build up my non-super stash. When in Australia build up my super stash.
