I live in Tweed Heads south, and drive past this every day on the cnr of Dry Dock Rd and fraser Dr you have an empty building about a 100 space car park (easy) and still water in a bay all that needs to be done is put a four way ramp some wash and fish cleaning bays. I have sounded around it is deep water 3-4m sand around the south and west of the bay to beach or boat about 120m long by 60m wide bay. You would have to go under a low bridge to get into the river out at high water you have about 3.5m of clearance, then and only then i might pay a $5 fee, this would take preasure off the other boat ramps around town. Dont know maybe all to easy or i might not be so smart.
