KEY POINTS:
A new report shows a 20 per cent rise in the value of investment projects in Australia for the past year to almost A$180 billion.
The latest Access Economics data shows that the value of Australia's investment projects is continuing to rise, despite the pressure of interest rates and a high Australian dollar.
Access Economics Director Chris Richardson says the strong global economy is driving investment, particularly in mining projects.
"We already have a mature investment boom in Australia, we already have investment, as a share of national income, higher than we've ever seen before.
"And yet to top that we're getting big projects getting the tick at the moment. Or in other words, what was already a boom is becoming a bigger boom.
"The outlook in China and India too has been strengthening," he added.
"Commodity prices are still good and there are expectations that many of them will continue to rise. Because of that more and more mining projects are getting the tick.
"Businesses have a very optimistic outlook of where the Australian economy's headed and they're putting their money where their mouth is."
Meanwhile, the Reserve Bank of Australia (RBA) is set to raise interest rates tomorrow for the second time this year, in a move that will almost certainly see rates return to the centre of the election campaign.
It will be the first time rates have been hiked in the middle of a federal election and is likely to test the political resolve of Coalition Prime Minister John Howard.
