The ACT is expected to see almost a 100 per cent spike in collisions with kangaroos on the road this year, leaving cyclists particularly exposed.

Key points: About 2,500 collisions with kangaroos are reported in Canberra in an average year

In an average year, around 2,500 kangaroo collisions are reported in Canberra, but in 2018 that number is already well over 3,000.

As drier conditions draw the macropods out of bushland, ACT Parks and Conservation is projecting that number will climb towards 5,000 by the end of the year, which is frightening for people like Damien O'Donovan.

He came off second best after hitting a kangaroo on a morning ride down Red Hill earlier this year.

"Next thing you know, I was over the handlebars and down the road," he said.

The incident put him in hospital with a concussion and left his bike ruined.

He did not know what happened or where he was after the accident, and if a friend was not there to help him he would have found himself in more trouble.

Later that night, the abundance of kangaroos on Canberra roads was really driven home.

"It was an incredible day, it began with me hitting a roo on my bike and then that evening coming back [home], my wife hit a kangaroo in our car," he said.

'Unbelievably lucky' not to be seriously injured

Steve Crispin was riding when he came across kangaroos hopping across the road.

He said he veered away from them, but one doubled-back, giving him no chance to avoid it, but some quick thinking in mid-air saved him from serious harm.

"I went head over the bars and basically performed a complete somersault and miraculously avoided contact with my head," he said.

His bike, on the other hand, was not as lucky, snapping in several places due to the impact.

With such low rainfall, what limited greenery there is often sits by the roadside, so Mr Crispin is urging cyclists to be particularly careful riding during the drought.

The Stromlo district has a large kangaroo population as well as a large cycling population, which can be a terrifying mix.

Competitive cyclists train at Stromlo's Criterium Track, surrounded by prime grazing areas for marsupials.

"You can imagine when there's 30 guys racing at high speed … it can really do some damage," Ian McVay of the Canberra Veterans Cycling Club said.

He is calling for higher fences around the track, which were once slated before being scrapped due to cost.

"There already has been substantial injuries to people," he said.

"How much money is a person's life [worth]? How do you value that?"

'We need more rangers': Struggling to meet demand

ACT Parks and Conservation are projected to get nearly double the number of callouts for collisions with kangaroos this year.

Ranger Mark Sweaney said they simply need more rangers to deal with all the callouts they have received, likely in part because the kangaroo population has rocketed up in the past 20 years.

"We have trouble even protecting busy roads and keeping drivers safe," he said.

"Coming up with solutions to protect road users as well as cyclists isn't easy."
