Funding for critical Queensland infrastructure has been put on the backburner in the budget, the State Government says, despite Federal Treasurer Josh Frydenberg announcing more than $2 billion for new projects.

The Budget included $2.6 billion for new road and rail projects — $425 million for Bruce Highway upgrades, $800 million on a Gateway Motorway extension from Bracken Ridge to Pine River, and $287 million for the Cairns Ring Road.

But Queensland Treasurer Jackie Trad said the majority of the funding won't be seen until the 2023-24 financial year.

"The money allocated for new infrastructure projects is $2.6 billion and let's be clear, $2.3 billion of that funding Queensland won't see for the next few years," she said.

"As they did in last year's budget, they make big commitments for big to infrastructure projects but we don't see the money for a very long time."

The road and rail funding is part of the Coalition Government's $100 billion infrastructure spend over a decade.

"Cranes, hard hats and heavy machinery will be seen across the country, as we build Australia for current and future generations," Josh Frydenberg told Federal Parliament.

"We will deliver new infrastructure projects to ease congestion in our cities, to unlock the potential of our regions."

However, Ms Trad said it was disappointing to see no funds had been put aside for the Cross River Rail.

"There was zero funding for Cross River Rail which will get people home faster and deliver thousands of jobs across our rapidly growing region," she said.

"While the LNP continue to ignore Cross River Rail, they are spending billions on similar projects in Victoria and New South Wales."

State Transport Minister Mark Bailey said Queenslanders were the poor cousins in the budget.

"They've given us a dud deal, other states have done a lot better. We've got nothing for Cross River Rail, M1 we only get 50 per cent," he said.

But Home Affairs Minister Peter Dutton said hundreds of millions of dollars were available and "projects could start tomorrow".

"There is federal funding committed and sitting on the table to build the Dohles Rocks Road on and off ramps to the Bruce Highway ($120m), the Linkfield Road overpass of the Bruce Highway duplication ($100m), the Young's Crossing flood proofing project ($7.5m) and $11m for additional parking at Ferny Grove rail station," he said in a statement.

RACQ head of public policy Rebecca Michael said the infrastructure funding was a big win for drivers.

"Some of the new projects that we didn't get wind of but are pleasantly surprised by are the Gateway Motorway for example, the Bracken Ridge to Pine River, where it hits the Bruce Highway there, $800 million allocated in the budget," she said.

"That's one of the last missing links for the Gateway and will go a long way to improving congestion on that part of the network."

She also welcomed money to set up National Faster Rail Agency, which will aim to deliver fast-rail projects across the country to ease transport gridlock in major cities.

"The establishment of the agency will see a business case being developed for fast rail connecting Brisbane to Moreton Bay, Sunshine Coast as well as Brisbane to the Sunshine Coast."

Emergency Response Fund to provide natural disaster relief

More disaster relief funding will also be on offer with the Federal Government to establish a new $3.9 billion national Emergency Response Fund for when future disasters impact the state.

It was revealed $150 million would be available every year following a "significant and catastrophic" disaster.

The fund will offer additional assistance to existing federal and state government natural disaster response programs.

AgForce president Georgie Somerset said she was glad to see continued support for flood and drought-affected producers in Queensland.

"A continued commitment to drought support and one of the clips in there was around farm household allowances and changes to that," she said.

"Also acknowledging that we still need to support people that are going through flood recovery and drought — we've had some communities that had no rain in the past few weeks."
