A $570 million infrastructure package for NSW has been announced by Prime Minister Scott Morrison, including the acceleration of $530 million in federal funding across three major regional projects.

Queensland, West Australia, and South Australia are also in line to get a $3.8 billion injection in infrastructure spending from the Morrison government in an effort to prop up the economy.

The NSW package is smaller compared to the other states, especially Queensland, which is set to receive a $1.3 billion fund.

Premier Gladys Berejiklian of New South Wales told reporters in Sydney "we're actually top of the tree which is why other states are having to be supported. We're doing very well in NSW but I always say to the (prime minister) we're able to fast track a lot of things if you give us that extra support and he's open to that and I'm sure they'll come to the party."

The federal government pumps billions into infrastructure projects across the country to boost Australia’s slowing economy.The Morrison Government has said that $212 million of the new package is planned to be spent in the upcoming 18 months.

“This is a key part of our plan for a stronger economy, and our pipeline of $100 billion worth of congestion-busting roads and rail,” Mr. Morrison said.

“We’re also injecting $20 million in extra funding for the final link of the vital Pacific Highway upgrade, and we’ve locked in $8.8 million for the Brig O’Johnston Bridge project at Clarence Town and $7.9 million for the Davey Road Interchange in Albury.”

Mr. Morrison said the infrastructure projects will help to cut travel times and make roads safer while also boosting employment and the economy.

Infrastructure Minister, Michael McCormack said in a statement that the key roads in regional NSW have also been heavily invested by the Australian Government.

 “That is why we are bringing forward $185 million for the Toowoomba to Seymour corridor under the Roads of Strategic Importance initiative, with significant funding already allocated to stage two of the Newell Highway’s Mungle Back Creek to Boggabilla project and $23 million allocated to the upgrade and sealing of priority sections of Tooraweenah Road,” Mr. McCormack said.

“We are also accelerating a $200 million investment in the Newell Highway to support construction of the Parkes Bypass and the delivery of Inland Rail, as well as $145 million for the Princes Highway corridor, including the Milton-Ulladulla Bypass.”

The deal was welcomed by NSW Transport and Roads Minister Andrew Constance.

 “Across the state, $55.6 billion is being invested in transport and roads infrastructure over the next four years, and we are pleased to be able to accelerate the delivery of some of the highest priority projects thanks to the Federal Government’s support,” Mr. Constance said.
