A Defence Force team and Department of Conservation team will also join the deployment - the 11th to Australia since 2001.
The Whangarei crew, who work for Forest Protection Services, are Canadian Garrett Urgay, Joey Cowen from Alaska, and locals Nathan Sullivan, Nicki Robinson who returned this week from a deployment to Melbourne, Martin White, and Taylor Snelgar.
For Mr Urgay, his first trip to New Zealand turned out to be his maiden voyage to Australia as well.
He arrived in Whangarei in mid-November last year and would return home in March.
"I am ecstatic. Tasmania will be a challenge for sure but those are the challenges I love. I'll be taking lots of pics ... soaking up everything while I am there," he said before departure from Whangarei Airport yesterday.
Owner of Forest Protection Services and experienced firefighter Kevin Ihaka said the Kiwi crew would do seven-day shifts before getting two days off, and would work in remote and steep areas.
"We're always well-represented in deployments such as these because we have large numbers of people available with a lot of skills who can get started pretty quickly," he said.
Mr Ihaka was among eight Whangarei firefighters who returned from Melbourne early this week after a two-week deployment.
