I have just added this to the map of places to fly your drone at Drone Scene - Location # 605
Land owner permission requirements unknown.
This is a stroll from my house so parking is no problem for me. I imagine that you could park in the marina car park - and visit the restaurant for a coffee to legitimise what you are doing.
The creek is accessible at most states of the tide, highwater might be a problem. There is a concrete sea wall with a lot of metal in it so keep reasonably clear else your cpmpass may object.
If you look at the pano you will see a field in the centre, zoom in and you will see a landing pad. That is just 50metres from any house or caravan so compliant with the drone code restrictions. An alternative site at low tide is the exposed sandy area at Black Point - the sailing club, accessible by footpath though parking isn’t possible.
The originator declared that this location was not in a flight restriction zone at the time of being flown. It remains the responsibility of any pilot to check for any changes before flying the same location.
