Health and climate change will also be among big-ticket items in the big-spending election-year budget.

Mr Stanhope will announce significant road projects to increase the capacity of existing arterial roads and to create the infrastructure for new greenfield sites.

Infrastructure investment will be the centrepiece of the budget to support housing affordability strategies and fight the skills shortage which the Government acknowledges is linked to population growth.

Last week, Mr Stanhope announced a five-year program of land releases for 15,000 new homes, including the imminent development of the new suburb of Molonglo.

The budget will include increased spending to upgrade the transport system in anticipation of future growth in new residential suburbs.

Tuggeranong is expected to be a beneficiary of significant road upgrades and there is also expected to be funding allocated for feasibility and scoping studies for major roads needed in future to support population growth in expanding areas of the city.

There is expected to be a significant boost to the capital program across the board.

While the ACT has enjoyed full employment, the election-year budget, boosted by property tax windfalls, will be aimed at stimulating economic growth.

Millions of dollars of additional funding for urban amenities will be available to help attract and retain people in Canberra.

Mr Stanhope said the ACT was the master of its own destiny and would not be waiting around for the Federal Government's budget, which will be handed down a week from today.

He would be driving the economy hard through today's budget.

"It's a good, strong budget considering the strength of our economy and responds to the priorities of this community in health, education, community safety, public amenity and the economy."
