The couple suffered multiple injuries in an accident on their way home from this year's Variety Bash event, from Bondi to Batt Reef Bash in Port Douglas.

The couple were to be transported by plane back to Sydney on Monday afternoon, with MarieJose continuing her rehabilitation at the Manly Waters Private Hospital.

It will be a great present for Mr Kennedy's birthday on Wednesday, September 11.

The couple had completed this year's event in Port Douglas and were on their way home when they had an accident in between Atherton and Innisfail, Far North Queensland.

They were airlifted to Townsville hospital for treatment.

Mrs Kennedy suffered a broken neck, multiple spinal fractures and broken ribs and a punctured lung.

She also suffered a broken ankle and dislocated her opposite knee and was placed into an induced coma at the scene.

Mr Kennedy underwent surgery for a broken/dislocated neck, with vertebrae repositioned and an artificial disc inserted along with a fusion. He also suffered a broken sternum and leg.

He was due to wear a halo for the next few months to support his head and neck, but that has been removed and he was released from hospital last Wednesday.

Speaking from Townsville, their son Troy said the couple are making steady progress.

"They are both doing quite well," he said " and it will be great to have them back in Sydney and closer to home.

"They are both in good spirits.

"Dad has been discharged and has been back every day to see Mum.

"Mum is doing well, she has built up her strength enough to enable her to go on the plane.

"She will continue her ongoing treatment at Manly. We are not sure for how long.

"But everything at this stage everything is going well.

"There is a 50 per cent chance at some stage she will need another operation on her neck."

He said despite a broken neck and multiple spinal fractures she remarkably has feeling and use of all her limbs.

"She busted virtually from skull to feet," he said.

"Everything is working okay, but unfortunately at this stage she can't bear weight with her broken leg but otherwise she's coming along in leaps and bounds.

"The hospital has been amazing. We can't thank them enough."

He said the couple were "a matching pair, with the same neck collars and moon boots".

"The response from Shoalhaven community has been overwhelming," he said.

"They can't believe the amount of support, messages of good wishes, visits and flowers they have received.

"They are overwhelmed and humbled.

"Community members have even been around to their home doing odd jobs. It's just been incredible and we can't thank everyone enough. Just amazing."

And as for the couple's Ford XY Falcon GT1, while it has been left badly damaged after the accident Mr Kennedy is already planning a major rebuild.

"The car is also set to start its long journey home," Troy said.

"It's been loaded on a truck and will be transported back to Nowra.

"Dad has plans to rebuild the car, mind you it might need a new body.

"He's looking forward to getting it back on the road and continue to take part in his much-loved Variety Bashes."
