You will not find any moorings for rent in the Burnett River.
Anchorages:-
1. The "duck pond" just inside the mouth of the river. Limited spots but with your draught you should find one. Short row to shore and pub and shopping centre a short walk away.
2. From there to the downsteam side of Port Marina. The further up the further from the shops.
3. You go past the bulk sugar terminal and you will see two "Bum's Bays". Those that anchor there have cars on the shore. Nuff said.
4. The town reach. Plenty of anchorages, public pontoon to tie your dinghy up and the whole city is right there.
Burnett Slipways is located slightly upstream.

There you have it. Cheers.
