"If you have a spouse I suggest you speak with your accountant about income splitting. If your employer would allow you to become a consultant that would be a bonus as you could start a company with a trust structure. This is what I operate with which allows me to bump my spouse up to the $180k with an affective tax rate of 30%"
Hopefully your accountant is up to date with PSI, Part IVA anti-avoidance rules etc.
