So you made a lot of money and you're are complaining about paying your fair share in tax? Capital gains tax is payable in the financial year in which the gain is made - so you knew about it as you had budgeted for it...I'm not sure what to make of your comments then as it appears you are being reactive rather than proactive. There are plenty of options available to reduce taxable income (ask any accountant).
The Budget Repair levy was proposed in the 2014/15 Budget and then legislated for the 3 financial years 14/15, 15/16 and 16/17:
Temporary budget repair levy
Your new motto will only get you into trouble - Australia & Thailand have a
tax treaty in place. It also surprises me that you appear not to have considered plenty of other options where income will not be taxed at the highest MTR (unless you are going to earn taxable income of greater than $180K indefinitely). If you're not happy with Australian tax and laws, there are other options....
