FRIENDS and colleagues of a couple killed in a horrific car crash on Sunday morning have revealed the pair had married just a couple of months ago and were set to open their own business.

Grace Cai, 27, and Calvin Zhou, 26, died when their blue hatchback was smashed into a tree after being rammed from behind as they sat at traffic lights on the corner of Ruthven and Alderley Sts at 4.45am on Australia Day.

The newlywed couple had returned to Australia two months ago after their Chinese wedding and were only weeks away from signing off on their own Sunshine Kebabs franchise.

Sunshine Kebabs human resources manager Muhammed Isbil, a colleague and friend to both Mr Zhou and Ms Cai, said they were fantastic people and called their death a tragic loss.


"I have been working with Grace and Calvin for two and a half years at Sunshine Kebabs and it was just so sad to hear they had died," Mr Isbil said.

"They were fantastic to work with. Always very hardworking, honest and happy people.

"They were most likely on their way home from work after shutting the store at 4.30am when the crash happened.

"I still can't believe it has happened. It is so sad."

It is believed both Mr Zhou and Ms Cai moved to Australia five years ago and met while studying accounting at the University of Southern Queensland.

Mr Isbil said the pair were popular and well liked.

"Grace and Calvin had a lot of friends from the university especially with the other international students," Mr Isbil said.

"Grace only just graduated with her degree and has been working for Sunshine Kebabs head office as an accountant while Calvin was managing our Margaret St store.

"Calvin and Grace were interested in running the city centre store and had saved up the money to buy the franchise.

"They had so much ahead of them."

USQ Vice-Chancellor Professor Jan Thomas said she was saddened by the death of the former USQ students.

"I am deeply saddened to learn of the car accident which claimed the lives of two promising young people on Australia Day," Prof Thomas said.

"Our sincere condolences and thoughts are with Grace and Calvin's family and friends.

"We are waiting on more information but we will be offering whatever available assistance we can to assist the families, staff and students involved."

Forensic Crash Unit investigators examined the crash site on Sunday.

The power of the collision was so strong it toppled a jacaranda tree.

Police said both cars were heading south along Ruthven St when a white car smashed into the back of the smaller hatchback.

The hatchback spun 180 degrees before hitting the tree.

The white Camry flipped, leaving the driver trapped.

Investigations into the crash are continuing.
