Having caught barra up in the Kimberly when I was younger I believe it is more the water quality rather than whether it is salt or fresh that has more bearing on the taste.

Did you have any trouble getting the barra to eat pellets and approx how long did you grow them out for? I live in Bunbury which is generally a touch cooler than Perth so am wondering if they would be viable or not. If not I guess I would go for trout. I am looking for at least a 2500 litre tank to use in my system but am unsure of what to get so far. Will probably be a water tank.
