Yeah, Oz recently made it that you couldn't contribute more than $25k p.a. to your retirement savings without a 48% tax on contributions.
Then last week a new tax on people who earn more than $100k in their super pension, or have more than $2M saved...only affects 0.4% of retirees today, but this is only the thin end, as contributory superannuation is relatively (decades) new, and kids entering the workforce will be accumulating for 45 years into the future.
