For what it's worth Australia ramped up it's infrastructure spending as part of the stimulus spending in response to the GFC.
Projects that were already in advanced stages of planning were given priority so that the benefits would be seen over the medium term. Where I live the state Government awarded contracts to build road and rail amongst other things.
So it turns out Australia has already spent record amounts on infrastructure in the last few years. Hence the large amount of infrastructure bonds that have been issued by the commonwealth government.
The Coalition also have a plan to promote the building of infrastructure. As part of that plan they hope to induce the State Governments to sell their publicly owned infrastructure in return for federal Government grants. The realised funds are to be put towards new infrastructure spending.
In the long term the Federal Government will actually get their money back because instead of the State Government receiving dividends from their owned infrastructure the Federal Government will gain tax revenue from the privatised entities.
