Secondly, who owns and manages the cabins at Bournda Beach, rented through the NSW Government Parks ? or owned?
I can only assist with a mud map to give the idea of Bournda being an isolated beach ?.
Also the cottage mentioned and the land in white including across Sapphire Coast Drive was owned privately by a family i believe , zooming you see Mandeni family cabins and Woodbine cabins area . (i lived there for 12 months some years ago ) These are all in the Southern end of Bournda , the other parts in green are Parks etc managed and have camp grounds etc .
The private areas I speak of may not still be with the same ownership but they have participated in educational endeavors and other ventures . This area bit further south is then connected to a retirement built up holiday area with woolworths and probably a Bunnings by now :0
Its hardly the deserted beach it was made out to be , so finding out where Melissa might have holidayed there would be impossible IMO
To the north is less built up with lakes and lagoons but is called Wallagoot .
Anyway I hope you find what you are looking for
