All eyes will be on Treasurer Jim Chalmers when he hands down his first budget, but it's certainly not the only hot topic in federal politics.
Tuesday night's budget will be delivered at a time of surging interest rates and inflation.
Prime Minister Anthony Albanese told Labor colleagues the economic plan would deliver election commitments and offer households targeted support.
"You can't change 10 years of chaos and neglect in one budget," he told a caucus meeting.
Opposition Leader Peter Dutton will get his chance to respond to the budget on Thursday night.
The government will also introduce legislation to crack down on data breaches.
The laws, drafted following widespread cyber hacks of Optus and Medibank customers, will increase the amount companies are fined for data breaches.
Industrial relations laws will also be up for debate.
The proposed changes stem from the jobs and skills summit earlier this year, allowing for multi-employer bargaining and improving gender pay equity.
Amendments to the defence home ownership assistance scheme and veterans' affairs will also be brought forward.
The Senate will deal with bills on paid domestic violence leave as well as anti-terrorist powers and changes to aged care.
The upper house will also debate the establishment of an agency called Jobs and Skills Australia, while incentives for pensioners to downsize and discounts on electric cars will also be discussed.
Greens senator Lidia Thorpe will also come under scrutiny after failing to disclose a relationship with a former bikie boss while sitting on a law enforcement committee.
The senator was set to face a censure motion but has referred herself to parliament's privileges committee, which investigates whether politicians have complied with disclosure rules.
