just found this

will check it out on the osi
'On the south eastern corner of Gorumna Island on Greatman’s Bay there is a small quay at Trawbaun and bottom fishing is best in the harbour at high water when flounder and plaice can be expected. Spinning also produces pollack to 1.5kgs. From the Old Pier at Glenmore dogfish, bullhuss, flounders and occasional ray can be caught while bottom fishing. Spinning is best for mackerel'.
Thanks again.
