Just do a search guys,the subject has been bought up b4 many times.
Other operators that still exist are North Coast Aviation and South West Air.
There are also the mission operators if you are religious.
You need a minimum of 1000 hours to get a go in a 206 or 208.
Co-pilot in a Otter or Bandit you could get a go with a bare CPL,although I think you would also require an IFR rating,as just about all of the Otters and remaining airworthy Bandits have no autopilots fitted.
I also forgot,Pacific have the remains of the old Airlink fleet,up at Goroka as well now,Mal is operating the last remaining 404 to support his helicopters around the country.
Good luck.
