The number of jobs advertised online dipped 0.6 per cent in June, marking a sixth consecutive month of falls recorded by the federal government’s Internet Vacancy Index.

The numbers, released by the Department of Jobs and Small Business on Wednesday, indicated a drop of 1,100 ads from the previous month and a 6.7 per cent slump in listings in the past year.

The IVI measure is based on a count of all new job ads posted on three employment websites – Seek, CareerOne and Australian JobSearch – during the month.

NSW ads had the biggest fall over the past 12 months, sliding 10.8 per cent, while the figures dropped 10.6 per cent in the Northern Territory and 6.6 per cent in Victoria.

The survey of online job classifieds also recorded a drop of 4.9 per cent in Queensland, a fall of 2.6 per cent in Western Australia and a 0.7 per cent dip in South Australia over the past year.

Job vacancies on an annual basis increased 7.1 per cent in the ACT and 10.5 per cent in Tasmania.
