I am sorry I have no experience personally, but there are a couple of astronomy clubs near you who I think would be happy to advise you. Send them an email:
Wollongong Amateur Astronomy Club
Meetings are held on the first Thursday of every month at the Unanderra Community Centre, 7:30PM.
Observing Nights are on the Fri/Sat nights at last quarter and new moon weekends.
Mr. Joe Perulero

Hope this helps
