I used to catch very large numbers of large Thread Fin Salmon over a meter long in the River down stream of Brisbane in the very early 80s onward. They have always been there but research has increased leading to the belief they were not there before. There used to be far more variety & size of fish in the Brisbane river systems prior to shallow reef damage South of the River Mouth due to coral mining, long term damage from close in trawling damaging sea grass areas & the development of Port of Brisbane removed or damaged grassy flats which had abundance of large prawns, many species dispersed or became smaller in general after its creation. But of course angling became more popular & everyone has a boat with a fish finder now so its no wonder fish stocks have been effected by this over the decades. The construction of Port of Brisbane made more habitat for larger species like Cod, Groper & Jew, & we have seen many changes in the river fish in the last 20 years.
The river he is in is the Brisbane river and they are fishing towards the mouth of it. Although the river has these fish all through it, I have found the best luck foe the threadfins are closer to the mouth.
