Funding for Queensland infrastructure has been put on the backburner in the budget 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 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,” Ms Trad said, "As they did in last year's budget, they make big commitments to big infrastructure projects but we don't see the money for a very long time."
