Hi David,
The right answer depends somewhat on where you live - north south or west ?
If you want somewhere to practice first in Sydney the NSAS has the best site in Sydney - bar none - at Terrey Hills, on a high ridge with low horizons in all directions. LMC SMC and the Coal Sack are all visible naked eye on a good night. You have to drive a long way to beat this one.
The next locations are in the blue mountains; see

Under item 3.
The Katoomba Airfield site is no longer available.
