I think in the 70's or 80's , their was a barra farm near the old rum distl. And one year high flood waters washed everything away. We have caught small barra near the bridge of the M1 , near the old rum factory. A friend of mine has a photo of a 4ft barra cuda he caught in the coomera river last year, He got sick of being busted off every time , so he went down there with a 37kg game rod and reel with 300kg mono leader. He pulled it in after an hour fight from his 12ft tinne.
If theres one there might be more????
