Senator Jacqui Lambie is preparing for spinal surgery, which will require her to miss the final two sessions of parliament this year.

The Tasmanian senator, known for her independent stance, has been grappling with a persistent back issue stemming from an injury she incurred during her time with the Australian Army.

A statement from Senator Lambie’s office, issued earlier today, indicated that her back condition has significantly worsened over the past three months.

“Her surgeon has confirmed that she will undergo spinal surgery in the coming weeks,” the statement announced.

Until the surgery is performed, Lambie’s medical team has prescribed bed rest and limited movement.

“Therefore, she will not be present in parliament for the final sitting weeks of the year,” her office said.

“Jacqui’s parliamentary advisory team will be in Canberra for the sitting weeks to ensure that Senator Lambie’s work will continue for the people of Tasmania and the veteran community.”

After enlisting in the army as an 18-year-old, Lambie was medically discharged 11 years later, in 2000, due to her back injury, which she said left her unable to move some days.

A year later, the Department of Veterans’ Affairs cancelled her military pension, saying she was no longer injured.

Lambie has previously opened up on the toll the injury took on her, leading to heavy painkiller use and a suicide attempt in 2009.

After successfully fighting to overturn the DVA’s decision through the courts, Lambie won a seat in the Senate and has become one of the most prominent advocates in parliament for veterans’ rights.
