There's plenty of fish in there, see?
There are, of course, a number of ways to classify Australian animals. I would guess that the largest number - of individuals, not groups - would be ants. They are so small, die so quickly, and would suffer greater fatalities than larger creatures because of their vulnerability and the shorter distance they can move to escape danger.
Longest lived? We tend to have turtles, not tortoises, so it might be a whale.
Shortest lived would again be another insect, perhaps a fly.
Fastest. Emus would be my guess. Slowest. No tortoises as mentioned and no sloths so snails?
I think the most expensive or valuable is going to be introduced like thoroughbred horses or pedigree pets, followed by champion bull, ram or somesuch.
The largest number of species seems as solid an approach as any so fish it is

I didn't follow my father and grandfathers' love for recreational fishing. It's understandable that there would be an attraction when you live several miles from the coast and there are no freshwater equivalents. But I am just as happy to take in the view and soak up the sun or go swimming; although some of the fish that were caught made good eating.
Based on what we found trawling national parks, I fear there will be more catching and eating fish; a contrast to the number of birdwatchers. It's not that we don't shoot and trap birds and mammals but fishing is a big thing in Australia.
That said, we visit aquariums, offices have fish tanks and (in a mirror of its surrounds) a goldfish bowl makes an acceptable pet accessory in the strictest bedsit.
The site to visit if you want a comprehensive list of freshwater fish is Native Fish. We'll replicate it below but without the taxonomy.
