Deputy Chief Minister Andrew Barr along with other senior government members will meet Infrastructure Partnerships Australia to gain support for public private partnerships in the territory.

While the form of funding has not before been used in the ACT Mr Barr said it would be critical in the delivery of the government's infrastructure plan.

Major projects include Capital Metro, City to the Lake, Supreme Court upgrades and the University of Canberra public hospital.

"There's a couple of billion dollars' worth of infrastructure projects for Canberra over the rest of this decade so our capacity to deliver those in that timeframe over the next seven years or so will be contingent on early productive engagement with the infrastructure community," Mr Barr said.

He said the government would look to explore the opportunities for a variety of procurement arrangements with senior infrastructure firms attending the meeting, including AECOM, the Macquarie Group and the Plenary Group.

"It's a significant outreach to the infrastructure community to put a number of our major projects on their radar and on the agenda for delivery in the coming years," Mr Barr said.

"We're beginning what is a serious pitch for private partnership in the delivery of our infrastructure projects."

Public private partnerships are infrastructure projects that are funded and operated collaboratively by government and private sector companies.

The government has previously stated its intention to develop projects through this method of delivery and has been developing a policy framework for potential partnerships to occur.

Mr Barr said the meeting, which will provide information from the soon-to-be-released Infrastructure Plan, demonstrated the ACT was moving out of the realm of the smaller-scale city into the space where state governments had traditionally operated.

"We've certainly recognised that if our city is going to grow then we're going to have to source investment from outside of Canberra - we're just simply too small," he said.

"We're just 2 per cent of the Australian economy and Australia's 2 per cent of the world economy so our longer-term economic future lies in being open to national and international investment in the city."

The ACT Property Council recently called for the government to use private sector participation to help deliver infrastructure in its "Declaration for Canberra's Centenary Year" document.

Mr Barr said it was not ambitious for the ACT to rely on private investment to deliver projects the government had planned as it was the preferred method of delivery across the country.

He said Federal Treasurer Joe Hockey had made it clear during the state treasurers meeting in Canberra on Wednesday that governments would have to step up investment efforts. He called for the sale of state and territory assets to pay for public infrastructure as a way of boosting the economy when the mining boom came to an end.

The ACT Assembly has approved the sale of ACTAB.

"We'll certainly look at the productive reinvestment of the proceeds of that sale into projects that will support the territory's longer-term economic growth," Mr Barr said.

"We'll need to look across our asset portfolio at options to raise capital to invest in new infrastructure."
