Hundreds of animals in the wild are not expected to survive Rockhampton's ongoing flooding crisis, wildlife carers say.

The Fitzroy River is expected to reach the major flood level of 8.5 metres today before reaching its peak of 9 metres on Thursday morning.

It is driving kangaroos, echidnas, birds, snakes, spiders and more in search of higher ground — sometimes at a risk to their lives.

On Tuesday morning a kangaroo fleeing floodwaters in Rockhampton was hit and killed by a car on Quay Street, by the river.

Another kangaroo, also hit and killed by a car on Tuesday morning, had a joey retrieved from its pouch.

Wildlife Rockhampton co-founder and rescue coordinator Svetlana Mitin said she managed to talk a man through how to retrieve the baby from its dead mother over the phone.

"The gentleman told me straight, 'I've never done it before, I don't know what to do, I don't know if I can do it, I don't want to do it'," Ms Mitin said.

"Because it was a dead kangaroo ... I find when you explain to people what needs to come they do it ... so all I said was 'it's not a big deal, it's not a yucky feeling, it just feels like you're touching a teddy bear'.

"He did an excellent job, he removed the joey ... it's like delivering a baby in the car."

The joey was taken to a nearby veterinary for further treatment.

Ms Mitin said the group's wildlife emergency phone has been ringing non-stop these past few days.

"We're just coping ... the calls we're getting through are enormous amounts," she said.

"In times like this we heavily rely on community assistance because we can provide advice but we physically can't be everywhere.

"This is one of the busiest times and to be honest I don't know what we're facing because we've never had this before to this proportion.

"It could be anything, it could be massive. I'd rather not think about it yet, we're just taking it day by day and hour by hour and dealing with what we have to do."

Snakes on a flood plain

CQ Snake Catchers' Benjamin Hansen said snakes and spiders were also on the move to drier grounds.

"We're getting more callouts ... there's a lot of things going around, not just snakes. We're getting calls for spiders, kangaroos and wallabies," Mr Hansen said.

"We've got two guys running around, they're averaging about 10 snakes each a day. A quiet day would be two to three," he said.

"We've had a few come out of cars — pretty much they're just seeking the drier ground.

"People are finding them inside, in the garden, or the garden sheds ... because people are cleaning up their yards a bit they're coming across them that way."

Mr Hansen himself came across a turtle trying to cross a road one morning recently.

"The passing traffic had made him retreat into his shell," he said.

"The turtle was inspected for any injuries but was found to have sustained not one. He was released into a nearby creek way."
