The unemployment rate fell to 7.5% from 9.1% three months earlier.

However, the underemployment rate amongst self-employed geoscientists, rose 2% to 20.5%, up from less than 15% six months ago.

The fall in geoscientist unemployment continues a gradual, downward trend that became evident in March 2016.

Over the March quarter, geoscientist unemployment increased in all states except Queensland and the Northern Territory. The biggest increase was in Victoria, where the unemployment rate increased from 5.9% to 11.8%.  In Queensland, the unemployment rate fell from 15.1% to 9.4%.

Underemployment increased in every state except South Australia, where the rate fell from 36.8% to 31.2%. 

Western Australia recorded an unemployment rate of 8.5% and underemployment rate of 17.6%.

"There is, clearly, evidence that improved industry activity is creating new employment opportunities for geoscientists, particularly in mineral exploration, but any talk of a boom seems premature," AIG president Andrew Waltho said. 

"We received excellent responses to the survey again, with more than 400 contributions received from geoscientists across Australia," he said.

The second quarter survey will open for contributions early in July.
