Labor will introduce laws on Wednesday aimed at streamlining access to government services by reducing the need to repeatedly provide information to different agencies.
Finance Minister Katy Gallagher said the laws aimed to cut red tape as well as allow information to be shared more easily between agencies.
"These are common sense reforms from the Albanese Labor government that will make a real difference in people's lives," Senator Gallagher said in a statement.
"Accessing everyday services shouldn't be difficult or burdensome and we're committed to streamlining services like the age pension and child support to make them simpler and easier to access.
"These proposals are straightforward, and I urge the coalition to support the government's bill to ensure Australians receive better, fairer experiences when accessing government services as soon as possible."
The bill will also increase information sharing between healthcare providers, provide people with more information about the rollout of NBN, and grant fuel companies greater flexibility to respond to supply disruptions.
The laws were fast-tracked after the government's economic reform roundtable held earlier this year recommended it to improve government inefficiencies.
