Just remember in NSW you can only anchor in "one place" for 28 days and anchor anywhere in NSW for a total of 90 days per year.
If you have a private mooring [licenced by RMS] there are limits to the days you can stay onboard.
Worse, fines are usually 1 unit PER day, a unit being worth $550. Gets expensive.
How to fix...stay in a marina.
Sorry to bring you bad news.
