LABOR has sharpened its attacks on the Abbott government's budget, arguing on Thursday it would hit low income women harder than men.
Opposition Leader Bill Shorten said that new figures, from left-leaning The Australia Institute, showed that "Tony Abbott has turned his back on working women".
The institute's figures showed that single mothers fared worse than most other demographics from proposed budget measures.
Modelling from the institute confirmed that women in the poorest 20% of households would be about $2500 worse off in 2017, while men would be only $1800 worse off.
Mr Shorten appealed to voter perceptions of the budget, describing the data as confirming that over "two million Australian women, as a result of the Abbott government, will be paying more tax on their superannuation.
However, Prime Minister Abbott on Wednesday night further affirmed his commitment to working women, citing his signature paid parental leave scheme.
He said he had shifted his own position on paid parental leave as if women were to have children, "they needed encouragement to be both mothers and workers".
