Just wondering if anyone has any tips, advice and info. on regulations for this.

One would think this is a total green light. Flying over the beach edge over the ocean, free of people or any property. Beaches tend to be a popular upload on youtube.

Australia obviously has endless beaches and coastline. That being said, its resort beaches tend to habited more heavily. Also being tourists hotspots, alot of these places have small airports or facilities for kinds of air-related activities. But there are no "no drones" signs whatsoever.

Also check each state has different regulations, in Victoria you cannot take-off in State Parks. Not all beaches are State Parks, but some are.http://parkweb.vic.gov.au/safety/be-safe-plan-ahead/rpas-drones
