Epsom and Bjerre are both really close to Secret Cove, 10 minute runs once you're out of the cove no wake zone. Epsom is best on the flood through high slack. Start near the light and head SW. Watch sonar for fish depth, follow that contour as it swings SW-W-NW.
There's a 300 foot flat right outside the cove that runs NW. You'll see prawn traps along that, base of the drop as usual. It extends north quite a way, no need to crowd other traps.
