As Piano Man mentioned, it is very much a case of right place, right time and most of all, the willingness to work hard.
Flying floats is great fun, but is not just a matter of showing up in the morning flying tourists around and then going home.
Continual washing of the aircraft is a must, especially in salt water and fuelling can be challenging with the majority of float ops being far far away from any bowsers and refuellers so climbing up on wings with a few jerry cans or filling the aircraft from a drum with a hand pump is something you will be doing a lot of as most float ops will run on min fuel for each flight.
Your best bet for a low timer would be the Gold Coast, Bill Lane in Port Macquarie or Strahan in Tas.
I'm pretty sure the guys in Kunners have all the guys they need.
Other float ops are;
Sydney Seaplanes (Beavers and Caravans) - do endo's but don't take on low timers
AFAIK
Air Whitsunday - as above, though have heard of guys get lucky
Hamilton Island Air - Caravan, fairly high requirements from the last AFAP ad
Cairns Seaplanes - one Beaver, don't do endo's
Pasparley Pearls Darwin - Fly a Malard, high requirements
Horizontal Waterfalls Broome - Caravan, unsure of requirements but most operators won't let you on a van until you're around the 500-800 min
The others (unless I've missed one) are mostly one-man-bands and will be unlikely places to get a job, though ICUS might not be out of the question.
Floats is very much a career choice in of its self, as mentioned it's not good for building hours and won't give you the things you need for an ATPL if your end goal is the airlines as there is no night flying and your instrument rating will be pretty much useless.
But damn is it a lot of fun!
