Yabbies are more on the southern end of the island.. throwing the cast net around Cowan will give some bait fish and there is plenty of flathead and stuff around that area.. The drop off to deeper water is in pretty close near the shop etc at Comboyuro Point so you can cast to pretty deep water from shore there too... The beauty of the island is that there is such a diverse range of fishing to be done there.. from shore or boat you have plenty of option.
