Abbott version is estimated to cost $5.5B, or roughly 3 times the cost of the current system introduced by Labor.
In that case there would be a saving of $1.86 billion from Labor's current scheme which could go to the lNP PPL scheme, leaving $3.72 billion paid in as a levy from big business.
Personally, I am opposed to such a scheme and also the same scheme that has been operating for some time with public servants including female politicians.
