Federal Treasurer Josh Frydenberg is set to deliver the first surplus budget in 12 years, plus a raft of pre-election sweeteners, on the back of strong coal and iron ore exports.
Mr Frydenberg will hand down his first budget on Tuesday night, just days out from Prime Minister Scott Morrison calling a federal election for May 11 or 18.
The Treasurer is expected to announce that the government will double the $530 tax break it gave last year to workers who earn between n $48,000 and $90,000, ensuring a $1000 boost for about 4.4 million on low and middle incomes, The Australian reports.
There will also be tax relief for those earning as little as $37,000 and as much as $126,000.
Labor has already flagged it will deliver its own economic statement later in the year if, as polls suggest, it wins the election - rendering the budget mostly redundant.
However, the opposition has signalled it will deliver bigger and fairer tax cuts, and put more money into schools and hospitals.
