But if you're going to lose them at 16-24 years anyway and if you make things so bad that the initial enthusiasm wanes at 12-15 years then that could be the strategy? Yes, the churn has happened slightly earlier.
Also, don't forget that those on 16 year AFPS75 pensions are dwindling fast - the last will be past that point in 2020. So holding out for 18, 20 and 22 will be required for an early departure payment.
This is complete guess-work on my part, but just like NEM not being a cost-saving exercise, it does all seem to point to a strategy that saves money in the longer term.
