The work will mainly involve tree felling burned trees before they fall, taking "the top" out of the fires' fuel, clearing existing and creating new firebreaks - the lines of containment to hinder fires spreading.
"Our biggest risk is falling trees, not flames," Mr Ihaka said.
But an equal challenge will be the conditions. The Northland team will work in high temperatures and high winds, the worst conditions for dealing with fire outbreaks in the tinder dry, furiously burning bush.
"It burns fast and comes back fast," Mr Ihaka said.
The Australians used different methods to those used in New Zealand, partly dictated by the type of dry, high-growing vegetation, he said. Firefighting did not usually involve attacking a fire close up. The Australian fire service also had sound safety controls, Mr Ihaka said.
"We've got to know a lot of people over there. They're always pleased to see us and treat us very well."
As well as Northlander Kieran Sullivan, who works full-time with Forest Protection Services as an apprentice mechanic and firefighter, the team includes three US firefighters who are spending their off-season working with the company. Jacob Lind, from Montana, and Forrest Hermans, from Alaska, are in Northland for the first time while Kevin Kraatz has worked here during Kiwi summers before and also answered the call to go to Australia with Forest Protection Services.
