• 1

  Australia publishes sales tax figures in Australian Dollar, revised periodically — enter the rate currently in force for your case in Australia rather than an older stored figure so the result matches the official calculation.

• 2

  Currency is part of the math: this Australia sales tax computes in Australian Dollar, so convert a foreign source figure first — applying a local rate to a foreign amount silently inflates or deflates the result.

• 3

  When comparing two options for Australia, run both through this sales tax with the same rate and the same Australian Dollar basis; then the difference you see reflects the options themselves rather than an inconsistency between the two inputs.

• Rates in Australia move — annually, or with each fiscal announcement — and a Sales Tax result computed from last year's figure misleads budgets and quotes alike. Re-enter the current rate whenever the underlying number changes.

• This page computes in Australian Dollar, Australia's currency: pasting a figure from a neighboring country's calculator mixes currencies silently. Re-run the number on the matching country page so the Australian Dollar basis holds.
