The measure is designed to tackle bracket creep, with wage inflation estimated to push 300,000 middle income earners into the second highest tax bracket where they'll be taxed 37 cents in every dollar they earn over A$80,000.
But the offer of tax relief for high wage earners has irked the estimated 75 per cent of Australians earning below what Morrison has declared the "average wage".
A total of A$80,000 is the average wage (November 2015) for fulltime workers, which make up 68 per cent of the workforce. For all income earners, the average wage is A$59,000, according to the Australian Bureau of Statistics.
Opposition Leader Bill Shorten has also slammed the offer of modest tax cuts, saying Australians wouldn't be bought by a few dollars in cuts.
"For the last three years, every day, the Liberal Government has been pick-pocketing voters and now at the very last minute they are offering a few dollars in hope that all will be forgiven," he said.
While missing out on tax cuts, the Government is promising to top up superannuation accounts of the low paid, according to the Australian Financial Review. Overly generous superannuation tax concessions enjoyed by the rich will be reined in.
There will also be a A$5 billion kitty for major projects across the country.
