Former police officer Bruce Daley, 56, who was driving the black Audi, was also killed, while the driver of the truck suffered minor injuries.

Ms McLean’s parents, Lisa and Peter, have shared details of their daughter’s slow recovery and how they moved to Brisbane to be by their daughter’s side.

The family is packing up their homes in Sydney and Adelaide for a permanent move to Brisbane.

However, due to Brisbane’s historically tight rental market, they are struggling to find a property close to the hospital that can also meet their daughter’s needs.

‘Our world has just come to a standstill. I was at a staff meeting. I literally got up and walked out and haven’t been back,” Ms McLean said The courier post.

“It’s crazy that we can just go on with our lives, and suddenly everything changes and we have to take our lives to the next level.”

Ms McLean spent 12 days in an induced coma, suffering serious injuries including the need to have her spleen removed.

The pair were on their way to a wedding when their silver sedan crashed into a truck after it was hit from behind by a speeding car.

The 23-year-old has to learn to walk, eat, swallow, hold a pencil and write again after suffering a serious brain injury. Unfortunately, she doesn’t remember her loved ones yet either.

“She has a severe traumatic brain injury. Her body can heal, her bones can be fixed. But as far as her head goes, we just don’t know,” Ms McLean said.

‘They really can’t give us any answers. That’s the hardest part: no one can give us the right answers. It’s just heartbreaking. She was in the prime of her life.”

Mr McLean said the crash shattered their “hearts into a million pieces” as he believes his daughter recognizes them but does not remember them.

Just three weeks before the crash, Ms McLean’s long-term boyfriend Harry Perez proposed and the couple had already started planning their wedding.

Mr Perez has also moved to Brisbane to be with the family and his fiancée during her long road to recovery.

Ms McLean had one more year of her marketing and communications studies at university to complete.

Her parents said she loved her job in Adelaide, where her best friend Ms Galbraith also lived.

She doesn’t know that her best friend has died.

The pair had been best friends since they met at school in Darwin in Year 7 and were inseparable. They often celebrated life’s big milestones together, such as birthdays, formal occasions and graduations.

Ms McLean and Ms Galbraith were traveling from Adelaide to Brisbane and were on their way to a high school friend’s wedding when the car they were in was hit.

Her parents hope their daughter will be transferred to the hospital’s Surgical, Treatment and Rehabilitation Service next week where she can begin her rehabilitation.

Doctors have said Ms McLean could remain in and out of hospital for the next two to three years.
