Hey mate,
I’d be heading from Scarborough ramp or Spinnakers marina at Bribie for the top of Moreton reefs. I leave from my home port at Beachmere and head up the Pearl channel, cross near Bulwer and out the Kianga channel weather and tide permitting.
Lots of shallow banks and pressure waves in the northern bay and probably best if you map out a route before you leave on the gps or Navionics app etc.
For the Barwon Banks I leave from Mooloolaba. Long and lumpy way home from Cleveland if turns to shit.
All in my humble opinion.
