Fishing Marks Point Sand Flats — Lake Macquarie Guide
An electric motor is a huge advantage here — stealth gets more bites on these open flats. Kayak anglers also do well, accessing the shallow water that boats with deeper drafts cannot reach. Target the top and bottom of tide when water stops moving briefly and flathead commit to striking. Blue swimmer crabs forage across the sandy bottom near the seagrass edges during the warmer months from October to March.
Launch from Marks Point boat ramp off Ada Street. Free parking is available but limited on weekends, so arrive early. Watch for oyster leases marked with poles and be aware that shallow areas can ground your boat on low tide — know your draft before you commit to a drift line.
Depth: 1-4m across the flats, some deeper gutters to 5m
