A Sunshine Coast cyclist and road safety campaigner who died while riding on Monday morning made a chilling prediction in January that he would be "hit" on the Sunshine Coast region's roads.

Father-of-three Cameron Frewer had been raising awareness of the safe passing distances between motorists and cyclists since moving to the area from Victoria in April last year.

He was killed while cycling on Caloundra Road around 6:00am on November 5.

Sunshine Coast Senior Inspector Jason Overland said police were investigating the cause of the incident.

Mr Frewer visited the ABC Sunshine Coast studios in January where he told Breakfast presenter Rob Blackmore of his concerns for his life each time he took his bike out on the region's roads.

"I ride with a front and rear camera now so I can see the cars coming close to me," he said.

"What the cameras do is give my wife and children some closure on the day I do get hit."

Mr Frewer said he did not believe it was a case of 'if' he would be hit, but when.

"I know one day I'm going to be hit. It is just a matter of when," he said.

Despite this, Mr Frewer said he was not going to stop going out on the roads.

"Why do you do it? Once you get the bike bug, most of the roads are fine," he said.

Rider regularly reported danger to police

Mr Frewer started the Facebook page Drive Safe, Pass Wide where he would post videos taken on his journeys of close calls with vehicles.

And he would regularly take these videos to lay complaints with police, who he claimed were not doing enough to prosecute motorists who broke the road rules by driving too close to cyclists.

In October, Mr Frewer posted a video on his Facebook page demonstrating how one in three motorists on a road in the Sunshine Coast's Palmwoods area failed to give the required 1.5-metre buffer.

In January, he told the ABC he had sent a complaint to the police including footage of drivers that "grossly violate the safe passing laws".

He received a response informing him that "two more close passes were deemed 'caution only' by local police in Queensland.

"My main submission detailed these incidents individually and gave some idea of the convoluted and subjectivity that is displayed by a force that will do all it can not to enforce, not to promote, and not to protect the vulnerable road user."

Cyclist policeman backs concerns

Inspector Overland, who also rides to work on a bicycle, said he had been in regular correspondence with Mr Frewer.

"Firstly, my condolences to the family," he said.

"Remember that cyclists are fragile."

He said he was also concerned "time to time" for his own safety when riding to work.

"You hope the people driving past aren't sleepy or under the influence," Inspector Overland said.

He said police generally picked up "one in 120 people" who had something in their blood stream they should not.

"Cameron was someone that brought road safety messages to Queensland Police Services' attention on a regular basis and I was corresponding with him on these complaints," he said.

In further correspondence between Mr Frewer and the ABC, he also expressed his concerns about speaking out because of death threats he said he had received.

After ABC Sunshine Coast shared Mr Frewer's interview on Facebook in January, it was removed due to inappropriate comments.

Bicycle Queensland's Anne Savage has described Mr Frewer as one of their "fiercest advocates" who fought every day to make roads safer for Australian cyclists.

The administrator of Mr Frewer's Drive Safe, Pass Wide Facebook page has asked for everyone to "step up".

"Australia used to have a wonderful culture of looking out for their fellow citizens and this culture has slowly eroded to selfish entitlement and hate towards others, especially vulnerable cyclists on our roads who are the last vilified group that society doesn't protect," the administrator wrote.

The administrator asked to remain anonymous for fear of 'trolls' and negative comments.
