Treasurer Josh Frydenberg will deliver his first federal budget at 7.30pm on Tuesday and voters in Dubbo told the Daily Liberal they have a range of items on their wish lists.

Lorraine Byrne wanted the government to help families struggling to make ends meet, especially those contending with massive power bills.

Her wish was granted on Sunday granted because the government announced it will offer a one-off payment to carers, aged pensioners, people on the disability support pension, single parenting payment recipients, veterans and  their eligible dependents.

To help with rising power prices, single people in those groups will get $75 before July and couples will have $125 deposited into their bank accounts.

Workers in the Dubbo region should get more money permanently in their pockets from July 1, if the government brings forward — or builds on promised reductions in income tax rates. 

Responding to ongoing voter dissatisfaction at the state of roads, the government has announced it will give councils an extra $1.1 billion in Roads to Recovery funding. 

More money will also be spent repairing black spots on roads where accidents happen more often, and a new national office of road safety will be established.

Business owner Phillip Williams said drought relief for country communities should be a priority for the government.

That's another wish the government is likely to grant, with changes to the Farm Household Allowance, which would increase support for farmers, expected to be announced.

Samantha Workman said she thinks more support should be given to disabled people, but the budget is expected to show billions less than was expected has been spent on the National Disability Insurance Scheme (NDIS).

The budget is tipped to be back in the black  — meaning the government should be collecting more than it spends for the first time in more than a decade since the global financial crisis hit and the budget entered a cycle of rising debt and deficits.

Once his government's new budget promises have been formally announced, Prime Minister Scott Morrison is expected to call a federal election.

If the Opposition does as expected and wins that election, Labor's Shadow Treasurer Chris Bowen said a Shorten government will bring down a major economic statement sometime between June and August.

"After six years of Liberal Government, the budget to be handed down six weeks before a Federal election is going to be a rather desperate throw of the dice attempt to change the political conversation, as opposed to a blueprint for reform, fiscal repair or growth," Mr Bowen said.

"This will be a political document from a desperate government, not worth the paper it's written on."
