Ms Galbraith was originally from the Northern Territory and worked as a nurse at Flinders Private Hospital in South Australia.

Mr Daley was retired from the Queensland Police Service in 2014 for medical reasons.

He had mentioned his mental health problems in disturbing online posts, including references to loneliness and suicide.

When asked whether the ex-police officer’s mental state would be a focus of the investigation, Detective Acting Inspector Chris Hansel told media he could not comment on the details.

‘I cannot comment on the exact scenarios at this time. As you will appreciate, it is a very complex investigation, a very confronting scene experienced by our first responders and the public last night,” he said.

“It would again be irresponsible of me to name a specific scenario without the full investigation having been done.”

Mr Daley died in the crash.

Debris from the wreck between Mr Daley’s Audi, the other sedan and a truck was spread over hundreds of meters in the tunnel at Mount Coot-Tha.

Mr Daley was traveling north in the tunnel when he collided with the sedan, which then crashed into a truck.

A witness claimed the Audi was traveling at 125mph for just a few seconds before crashing into the sedan. Courier mail reported.

Mr Daley drove north into the tunnel in a black Audi S3, which witnesses said was traveling at a speed of 125mph.

“I was driving behind the Audi… for some reason (the driver) slowed down and stopped as we entered the tunnel,” the witness said.

‘(The driver) did not indicate or activate any hazards… I signaled around him and continued driving… a few people beeped at him.’

The witness then heard a “car engine roaring” as the Audi “passed me in the tunnel at 120mph,” and about 20 seconds later “smoke and debris were flying.”

The speed limit in the Legacy Way tunnel is 50 mph.

Another witness said: ‘I was just out of sight behind it when it happened.’

‘The vehicle pictured was directly in front of me and accelerated rapidly eastwards just after the first speed camera until it was out of sight.’

Photos from the crash scene showed the severity of the crash, which left the Audi largely destroyed.

The collision closed the city tunnel, with both inbound and outbound lanes closed for more than two hours during rush hour.

Queensland police officer Acting Inspector Stephen Crabbe described the crash scene as “extensive” on Wednesday.

“Police are appealing for information about a black Audi s3 believed to have been traveling north on the Centenary Motorway through the Legacy Way tunnel,” he told a news conference.
