The state of Victoria in Australia is co-ordinating the Australian effort, and Darrin McKenzie, from the Victorian Department of Environment and Primary Industries, said conditions would be challenging.
"[Canada has] had a long fire season so far, their crews are getting tired and fatigue is becoming an issue for them, so they've requested some assistance," McKenzie said.
"It's very hot and very dry. There are a number of large fires burning and they've got new fires starting almost every day at the moment," he said.
"The conditions are very similar to Victoria; it's a very fire-prone area. They have large tracts of forested area, very rugged mountain terrain.
"We've got incident management teams heading across, and we also have specialist roles in terms of fire commanders and fire behaviour specialists."
