You'd probably have a better chance of getting in with the TFS than anything
else.
http://www.fire.tas.gov.au/mysite/enter.jsp One fire service, with full-timers, retained (paid on-call) and volunteer.
Depending on where you live and how old you are, you should be able to get
into your local brigade, at least as a vol. From vague memory, only metro
Hobart, Lonnie, Devonport & Burnie are all-career stations, & I'm not sure
about Devonport & Burnie. Then as paid positions come up, you'd be well
placed to go for them.
Otherwise, Forestry & possibly National Parks also take on seasonal f/f's.
In any event, you'll want to get matric under your belt before doing full-
time anything. Doubt you'll get a gap year as a paid firie. There's as
much to learn & become proficient in as there is in any 3 or 4 year
apprenticeship. This is true whether you are a vollie or a career f/f.
