This bigger pregnant prawn fly is one of my goto flies here in Central Queensland estuary waters. I often fish it when targeting barra, grunter, jacks and flathead in estuary and harbour waters but it's not unusual to hook up on queenfish, travally or other fish that eat prawns.
This fly is a down bib version of my 'articulated swimmer' range of flies and adopts the "sunburst colours" of a number of popular barramundi lures. Like those lures this fly comes into its own when fishing water that is tannin stained or carrying a lot of sediment.
