The ALP is tight-lipped about which seats the Opposition Leader will visit, but it is understood he will travel to western Sydney and outer-suburban Melbourne.

Mr Shorten said the Prime Minister's ''budget mess'' had not gone away simply because he had gone overseas.

''Coalition MPs can't just sit in their offices and hide from scrutiny, they need to hear what people really think about this unfair budget, and they need to pass the message on to Tony Abbott,'' he said.

''They should be telling the Prime Minister how much his budget will hurt their electorates, not staying quiet. If they go back to Canberra next week and don't speak out against the $7 GP tax and the pension cuts, their communities won't forgive them.

''If the Coalition doesn't want to sell their budget, we'll sell it for them. We'll be telling Australians about the new taxes, the cost of living increases and the savage cuts. And we'll be reminding people Tony Abbott lied to them before the election.''
