ANZ's latest survey of business sentiment found confidence had hit its highest level since April 1999.
Consumer confidence is also improving, with the latest ANZ-Roy Morgan survey finding sentiment at a three-year high.
But these signs of growing financial optimism were yet to spill over into wage growth, Faulding said.
"While strong salary growth and job creation are yet to be seen across the board, some industries are faring better than others with growing momentum in the housing market and construction sector in particular boosting figures."
The average salary for jobs in construction had risen by more than $6,000 since July last year, Seek said.
Job vacancies in the construction sector were also booming, up 46 per cent from a year ago, compared to a 6 per cent rise in jobs nationally.
Faulding said that based on recent confidence surveys, she expected wage inflation to build and broaden over the next six to eighteen months.
