Hmmm ... am sorry but am philosophically opposed to any Govt anywhere 'topping up anyone's wages' ... !!
One of the largest aged care providers in Australia now is BUPA which is soooo huge and profitable that it buys 'private health insurance' outfits out of petty cash.
Aged Care workers are like any industry and need to unionise or lobby for arbitration for wage/conditions like any other.
And, just as the NSW Nurses are doing above ... although, there aren't many nurses anywhere not on about $70k a year.
