The number of Australian jobs posted on the Internet hit an all-time high in June, according to the Olivier Internet Job Index.
The index rose 4 percent in June with 163,837 jobs appearing on the major job boards each week on average.
Oliver Group director Helen Oliver said it was a substantial increase at a time when there's traditionally a market dip.
"There was a flurry at the beginning of the month. It's a superb time to be looking for a job," Oliver said.
The strongest growth in June was in multimedia while IT jobs were up 1.46 percent in June, that's 55.75 percent higher than at the same time last year. "This is not a candidate-short market, it is a skills shortage," she said.
"It takes longer to find the right people for jobs and employers are starting to search earlier."
Oliver said the federal government's Industrial Relations reforms and changing economic conditions could affect the Australian work force.
"People have been changing jobs more often - there's been an explosion of opportunities and so job security isn't so important," she said.
"It's been 'easy come easy go'. However, the Industrial Relations reforms may start to change the balance."
As a result of the shortage, Oliver said businesses were hiring overseas workers and employing mature age workers.
