Ombudsman Michael Manthorpe released a report on Monday looking at behaviour training for ADF recruits.

Mr Manthorpe said while most reports of abuse related to incidents occurring many years ago, his office had also received around 70 reports of unacceptable behaviour and abuse relating to incidents reported to have occurred since June 30, 2014.

"We continue to receive some recent reports of unacceptable workplace behaviour and abuse," he said in the report.

"These recent cases do not point to systemic abuse in the manner which was apparent in Defence in earlier periods, however, the fact that incidents continue to occur reinforces the importance of continued vigilance."

Most recruits are aged between 17 and 24, with "general entry" training spanning 11 weeks.

Training would not be able to eliminate all instances of inappropriate behaviour or abuse, but was an important preventative tool and would help build a culture where incidents are reported and appropriately dealt with, the ombudsman said.

The ombudsman report found no significant concerns with the ADF's approach to recruit training, being "largely satisfied" the curriculum reflects rules on on required behaviours.

But he made five recommendations for changes, mostly dealing with the evaluation of training and identifying current risks and issues in the ADF to improve training.

Since 2011 there have been a series of reports, recommendations and responses relating to the ADF's culture, including the treatment of women, alcohol use, social media use, complaint handling and incident management.
