So I think you have your answer, Dick.
A country whose GA fleet is mere rounding errors on the size and hours amassed in the USA knows better. You should feel comforted by the fact that your helicopter will be 'safer' in Australia.
If you fly your helicopter past the date on which the compass has to be calibrated, without having it calibrated, you'd be a dangerous criminal even if it remained accurate. However, if the calibrated compass suffered a random failure in flight, you're safe because the compass had been calibrated.
You see: It's all about 'safety'.
