The olive thread head McGoo is another terrific damsel imitation that works very well in all of Australia's shallow impoundments. Whether it is farm dams or large lakes, this semi imitative pattern catches fish. When damsel flies and dragonflies are around, this McGoo pattern is extremely effective. The olive thread head lends itself to being used when the water is clear and the fish are being difficult to catch.
Using slow, long draws followed by long pauses is a good retrieve to start with over the top of weed beds. It doesn't matter if you are fishing off the shore with a floating line or out of a boat, deep and fast, this McGoo rarely lets you down. No Australian fly box is complete without some of these. Barbless.
