Dubai vs Portugal for Australians leaving home
The regimes are genuinely different: Dubai is a zero personal tax system while Portugal runs worldwide tax, which of your income streams each one actually touches matters more than any headline rate.
Neither has an Australian tax treaty, no tie-breaker in either direction if your residency is contested, and full withholding on Australian dividends and interest you keep. Your facts on the ground have to do all the work.
Portugal is the cheaper place to live day to day, roughly 65% of Sydney's basket against Dubai's 95% (indicative, ex-rent), which can outweigh a thinner tax saving over a full household budget.

Honest downsides, side by side
Every destination hub on this site carries its downsides in the open. Here are both lists together, because the right question is rarely “which is better?” and usually “which set of problems would you rather live with?”
Dubai
- No Australia tax treaty: if your residency status is contested, there is no tie-breaker. You can be fully taxed in both places on the same income.
- Summer is genuinely brutal; many expat families leave for two months a year (watch your Australian day count when they head "home").
- Renting and schooling costs rival Sydney; the tax saving is real but the cost base is not cheap.
- Everything rests on your visa: lose the job, and the clock starts on leaving.
Portugal
- No Australia tax treaty: a contested residency year can leave the same income fully taxed in both countries with only messy unilateral credits between you and double tax.
- NHR is gone for new arrivals, the 20% IFICI successor is narrow, and most Australians will face full progressive rates up to 48% plus 28% on investments.
- Salaries and bureaucracy are Southern European: local pay is low, AIMA appointment backlogs are real, and everything official takes months.
- It is the single worst time zone on this list for keeping Australian clients, 9, 10 hours behind AEST means your overlap is their evening.
- Winter housing is genuinely cold and damp; central heating is the exception, not the rule.
