Job advertisements on the internet fell by 2.3 per cent in December, Federal Government figures show.
The Department of Education, Employment and Workplace Relations internet vacancy index declined to a seasonally adjusted 64.9 points in the month, to be 24.8 per cent lower than a year ago.
In trend terms, internet job ads are at their lowest since the series began in January 2006.
However, vacancies increased in four of the eight occupational groups monitored by the department.
The strongest monthly increase was for machinery operators and drivers, rising by 4.6 per cent, followed by a 2.2 per cent rise in community and personal service workers.
On the other hand, demand for professional workers dropped by five per cent in the month and there was a 4.2 per cent decline in vacancies for clerical and administrative workers.
Only Tasmania and the Northern Territory posted a rise in jobs ads in December, increasing by 1.8 per cent and 0.5 per cent respectively.
The biggest fall was in Victoria, a drop of three per cent in the month.
Jobs ads declined in all states and territories over the year, led by a 32.2 per cent fall in Queensland.
