There is a ride from Little Beach Nelson Bay NSW out to Broughton Island on the Monday of the long weekend.
Plan to leave the ramp at 8am & be back by 12. Weather is forecast as hot 30c with light winds till around 1pm.
If local to Nelson Bay & Lake Macquarie then these 2 FB pages are what we use to get rides going
