Aid organisation Save the Children says it is frustrated and angry over a "disturbing" intelligence report that sparked the Moss review into allegations of sexual misconduct at the Nauru detention centre.

The review was set up to examine allegations that staff from the charity acted inappropriately at the Nauru detention centre.

The review, headed by former integrity commissioner Phillip Moss, was announced by former immigration minister Scott Morrison in October and is due to be released on Tuesday.

The Moss review examined why 10 Save the Children aid workers were sent home from the detention centre and whether they fabricated allegations of sexual abuse.

An intelligence report released this week by Greens Senator Sarah Hanson-Young showed there was no evidence to support claims of misconduct and the review was based on vague allegations.

The report stated; "It is considered probable that refugee advocates and some service providers are engaged with asylum seekers, and refugees, to manufacture situations where 'evidence' can be obtained of the unsuitability of Nauru for processing and resettlement..."

It also claimed "It is probable there is a degree of internal and external coaching, and encouragement, to achieve evacuations to Australia through self-harm actions."

However, Senator Hanson-Young said the review was a witch hunt.

"The reason that I took the extraordinary step to read the report into Hansard is that I believe the Save the Children workers who are implicated in the report, and were fired from their jobs, deserve to know what accusations were being made against them," she said.

"We can't trust the Government on this - they now have form - we've seen that from the exposure of the intelligence report.

"The Government simply cannot be trusted to tell the truth to the Australian public.

"The report must be released in full - there's no two ways about that.

"The report simply contains a series of vague allegations without any actual evidence of inappropriate action by any staff member in the centre.

"It seems, from this intelligence report, that the only crime committed by those employees was to report accusations of abuse and the inappropriate behaviour of security guards, who are employed by the very same company that wrote this intelligence report."

Save the Children spokesman Matt Tinkler described the intelligence report as "disturbing" and the organisation was frustrated by the allegations.

"Especially as you can imagine for those staff who ultimately lost their jobs as a result of this so-called intelligence report," he said.

"It's not the kind of report that should be relied upon to attack an organisation like Save the Children."

Immigration Minister Peter Dutton's office declined to comment.
