Thanks for the tips guys, i'm in Queensland (Nambour, Sunshine coast)
I have since found out that the 'koi' are just big goldfish (they are not mine but i'm not allowed to get rid of them)
Ideally i'd like to have all natives in the pond - bass, saratoga, salmontail catfish etc. so i'll have to do something with the goldfish.
Meanwhile i'll keep looking for a juv. saratoga, there a a few around and they're pretty expensive - $90 for 1.5'!

Brisbanes temps are great for Koi. But its the grass carp/normal carp that are released by hobbyists which is why they are illegal.
