Defence abuse probe overdue: Lambie

Independent senator Jacqui Lambie says a royal commission into defence force abuse is long overdue.

There is speculation the Defence Abuse Response Taskforce will recommend a royal commission in its long-awaited report on Wednesday.

"Beautiful, that'd be great," Senator Lambie told reporters in Canberra.

"These victims, they want to have their say. It's time to call that royal commission. It's well overdue."

The taskforce was formed in 2012 to examine about 2400 historical allegations of abuse within the defence force, in some cases recommending victims be compensated.

One outstanding issue remains a series of sexual assaults on female cadets at the Australian Defence Force Academy in the mid-1990s.

That has been referred to as the ADFA-24, and some alleged perpetrators remain in the defence force.

Labor defence spokesman Stephen Conroy said it was worthwhile to "have a conversation" about the need for a royal commission, depending on DART's findings.
