OPPOSITION Leader Bill Shorten said "millions of Australians" were in for bad news.
The Abbott government had prepared "a budget of broken promises and twisted priorities", he told a media conference this week.
Mr Shorten said it would include increased tax for some, pressure on the carer's pension and making parents pay to take sick children to a doctor.
"This budget is scaring the daylights out of carers and pensioners, it's frustrating Australians who go to work every day who cannot believe that this prime minister, when he was opposition leader, made himself the moral paragon.
"He made himself the Mother Teresa of opposition leaders.
"Tony Abbott staked his reputation on not breaking election promises.
"Now we see Tony Abbott conflating a false budget emergency and it is the sick, it is the elderly, it is the vulnerable, it is the carers, it is the people who go to work every day who are paying . . ."
