Not necessarily, as long as a member has the option of removing after tax personal contributions, no one should be able to complain.
Other than that, grandfathering of funds in the pension phase would probably be required, as the pension was commenced with existing rules.
Somewhat like what would happen if a change was made to negative gearing.
That would put super back to just a savings account, see how that works.lol
On the other side of the equation, how many low income Australian workers paying their compulsory 9.25% into Super - costing them 15% PLUS costs - have complaints about the co-contribution scheme being withdrawn ?
Especially when they're told that super is all about saving for their retirement, but oops...they're paying up to 15% more than if they were to take their meagre 9.25% $$ (which will become 12% in 2019 ) home and pay their loans off... while at the same time funds with over $10million has reportedly doubled over the last three years?
And then to be told that whether low income earners receive the co-contribution or not will make no difference in the end because they will get the pension anyway ?
