Senator Helen Polley says now is the time for Senator Jacqui Lambie to come clean on medevac deal

It comes as Senator Lambie remains silent on the details of the deal despite promising to release them by the end of 2020 if the government did not.

The medical evacuation laws allowed for people in offshore detention centres who were deemed, by an independent advisory panel, to need medical attention to be transferred to Australia for that treatment.

It was passed by Labor and the Greens in February 2019 before being repealed later that year with the support of One Nation and Senator Lambie.

At the time Senator Lambie said she could not reveal the details of an agreement with the coalition to remove the legislation due to national security risks.

But, earlier this year she told ABC's Four Corners program that she would tell the public the details of the deal by the end of the year if the government didn't.

Tasmanian Labor senator Helen Polley said now was the time for Senator Lambie to come clean because the government wouldn't.

"The public needs to know the details of what deal was done around medevac," she said.

"People have respected Jacqui Lambie as being open and honest, well this is her opportunity to come clean and tell the Tasmanian community, in fact tell all Australians, what the deal was that she has done."

The government have repeatedly denied making a deal with Senator Lambie in relation to the medevac laws.

Senator Lambie was contacted for comment.
