Hi Sam,
Despite the recent fires that have closed the Warrumbungles National Park,
the nearby Warrumbungles Mountain Mountain, which is outside the park,
is still hard to beat as far as a combination of dark skies and amenity.
It is approximately six hours drive from Sydney and has the convenience of
expansive grounds to set your telescope up on and yet only a short walk
back to your room for coffee. The owners understand the needs of observers
and can recommend to you where to set up. We were last there a couple of
months ago and though the fire damaged trees at the front of the property,
the grassed area from where one observes was green.
A little further afield is Mount Kaputar, which one typically drives to from
Narrabri. You are at 1500m altitude (incredibly, despite its latitude, there are
snow gums up there), but you need to arrange with the ranger in Narrabri to
get access to the gravel pit area which doubles as the helicopter landing pad.
This area is accessible by foot but has a gate and so if you have a large scope,
it is more convenient to borrow the key to access this particular spot which is cleared
of trees. Mt Kaputar also has three large incredibly comfortable cabins which
include their own bathrooms with hot showers, kitchens and enough beds and bunks
for an entire family. All available at near giveaway prices of $77 per night for the entire cabin.
One would be pressed to find a better deal in Australia.

Alternatively, one can camp.
As I have mentioned on this forum before, if one gets far away from any city or town,
essentially the country is one big potential observing field. Outside of areas
that have light pollution, the experience is generally that the observing will be
limited by the prevailing transparency and seeing.
Whilst I will make the drive to the Warrumbungles Mountain Motel in six hours, Narrabri is
a little over 7 and by the time you make it up the winding road to the top of
Kaputar itself, closer to 8.
Having said that, when you used the expression "best place in NSW", I would
certainly rate Mount Kaputar as way up there. At one point it had been considered
for the site of the Anglo Australian Telescope. The views from the top are certainly
to die for and on clear nights the skies are probably as good as they get in the state.
