OVERVIEW
The hidden trap: UK has a 60% effective rate between £100,000-£125,140 as your personal allowance vanishes—Australia has no such trap. At £80,000 (~A$155,000), UK charges ~£23,000 (income tax + NI) while Australia charges ~A$41,500 (~£21,400, income tax + Medicare), so Australia is about £1,600 a year cheaper. At £50,000 the UK is slightly cheaper (about £630), and the gap in Australia's favour grows from around £75,000 upward (about £2,000 at £100,000, £5,900 at £125,000). Choose UK if: you earn around £50,000 or less, want NHS included, or plan to use ISAs. Choose Australia if: you earn £75,000+ (and especially £100,000+ to avoid the 60% trap), want mandatory 12% employer Super, or prefer higher base salaries. All conversions use about A$1.94 to £1.

FAQ

Frequently Asked Questions

How much tax will I pay at £100,000 in UK vs Australia?

At £100,000: UK charges ~£31,400 (income tax + National Insurance). Australia at the equivalent A$194,000 charges ~A$57,000 (~£29,400, income tax + Medicare), at about A$1.94 to £1. But WARNING: the UK's 60% trap starts here. Earn £110,000 and you'll pay ~£37,600 in UK. Australia has no such trap—consistent marginal rates.

What is the UK's 60% tax trap and does Australia have it?

Between £100,000-£125,140, UK reduces your £12,570 personal allowance by £1 for every £2 earned. Combined with 40% tax + 2% NI = effective 60% rate. Australia has no equivalent—their thresholds don't phase out. This is the main reason high earners prefer Australia.

How does Superannuation compare to UK workplace pensions?

Australia mandates 12% employer Super contributions on top of salary. UK auto-enrolment requires just 3% employer contribution (plus 5% employee). On a £80,000 salary, that's ~£9,600/year vs £2,400/year into retirement. Over 30 years, the difference compounds to £200,000+.

Is healthcare included in both countries' taxes?

UK: NHS is free at point of use, funded through general taxation and NI. Australia: Medicare (public system) costs 2% levy on taxable income. Both provide universal coverage, but Australia charges explicitly while UK bundles it in. Private health is cheaper in Australia (~A$2,000/year vs £1,500+ in UK).

Which country is better for £50,000-£80,000 earners?

At this range, UK and Australia are fairly similar in total tax burden: about 21-29% effective in the UK at £50,000-£80,000, and about 22-27% in Australia at the equivalent A$97,000-A$155,000. The UK is slightly cheaper at £50,000 (by about £630), but Australia is cheaper from around £75,000 (about £1,550 at £75,000 and £1,640 at £80,000). Australia's advantage grows further above £100,000, where the UK's 60% trap begins biting.
