More than a third of Australian jobs face the threat of being taken over by computers or machines over the next decade.

The new Organisation for Economic Co-operation and Development (OECD) Outlook report says 36 percent of Australian jobs face a significant or high risk of automation.  It suggested that a large portion of adults will need to upskill or retrain to meet the needs of the future job market.

Australia also has one of the highest rates of casual workers - one in four, with more than half of them having no guaranteed hours.  The high rate of people who work fewer than 19 hours a week gave Australia one of the largest increases in underemployment within the 34 OECD countries since 2007.

"Young people with medium- and high-level education have seen increases in their probability of low-paid employment in Australia since 2006," the report noted.  "The labour market experiences of many young people and of those with less than tertiary education has worsened over the past decade," it added.

"In fact, young people with less than tertiary education have been particularly affected, with more of them being under-employed, non-employed or receiving low pay."
