Minister keen for Brittany Higgins outcome

The AFP has handed over a brief of evidence to prosecutors in the ACT, who are now weighing up whether to press charges.

Home Affairs Minister Karen Andrews said prosecutors were considering a range of factors including the likelihood of a conviction.

"The sooner this gets resolved - for everyone concerned, particularly for Brittany Higgins, but everyone who has been affected by this - the better," she told Brisbane radio 4BC on Wednesday.

Earlier this year, Ms Higgins came forward with allegations she was raped by a fellow Liberal Party staffer in 2019.

Prosecutors received a brief of evidence from police in late June.

The complaint triggered a major reckoning of toxic workplace culture inside Parliament House.

The Morrison government has since agreed to adopt an independent complaints mechanism for serious incidents.

It is also offering voluntary one-hour training sessions on respectful workplaces for politicians and their staff.

Ms Andrews acknowledged the sessions alone were not the solution.

"It's actually a start at least," she said.

"It's not the answer, it's not the answer, but all MPs and senators and their staff should actually go through that training process."

At least one member of the government, Queensland senator Gerard Rennick, has refused to take part.

Ms Andrews has noticed a cultural shift inside Parliament House since Ms Higgins came forward.

"It's quieter since this," she said, adding the building was also "not as boozy".

"So that's a positive and I don't like the amount of alcohol that is consumed during a range of events at Parliament House.

"Now, that's been helped by the fact there haven't been many events during COVID, but it's a workplace so I've always been concerned about that."

Ms Andrews hopes the culture continues to improve, saying "quite frankly it is needed".
