A slowing trend in job advertisements warns of dwindling jobs growth, according to an ANZ economist.
The number of jobs advertised on the internet and in newspapers has fallen, the ANZ's monthly data shows.
The number of job ads fell 0.4 per cent in seasonally adjusted terms between June and July.
Ads were still 9.3 per cent higher than a year earlier, but ANZ chief economist Warren Hogan said the trend had slowed in recent months.
The ANZ's trend measure of job ads, which smooths out the ups and downs in the seasonally adjusted figures, grew by 0.4 per cent in July.

That was only a third of its 1.2 per cent per monthly growth rate seen at the recent peak in September and October last year.
"The slower growth in job advertising supports our view that employment growth will slow in the second half of 2015 following unexpectedly strong outcomes since late 2014," Mr Hogan said.
Despite the strong jobs growth, total household income has grown only modestly, because the jobs being created in the services sector are paid significantly less than the jobs lost in mining manufacturing industries.
"As a result, growth in household spending has remained sluggish," Mr Hogan said.
That in turn will act as a headwind to economic activity and hiring.
Official figures show the trend in growth in the number of people with a job has slowed, from a peak of over 27,000 a month in January to 15,000 in June.
The figures will be updated by the Australian Bureau of Statistics with July estimates on Thursday.
The median forecast in an AAP survey of economists is for seasonally adjusted employment growth of 10,000 in July, with an even split between those expecting the unemployment rate to stay at 6.0 per cent or edge up to 6.1 per cent.
