British spotter 1st time in Sydney advice please

[Rob.b]

Hi guys I am British spotter and will be visiting Sydney for a couple of weeks in April 2016. Itss while away but I am looking for some general advice for planning purposes as its my first time in Aus. I am happy with there being plenty of info about SYD but its the small fields I am interested in.
What is the general attitude to airside access at Bankstown and Camden? I will be photographing everything and would love some airside access, will also take numbers.
Also planning trips to Richmond, and a few days at Williamstown and then down to Nowra. Not totally spotting as I will have the Mrs with me.Again what the the RAAF/RAN attitude to spotting from the fence? Any out of the way places that I have not noticed on google earth?
My main interests are classic 30-50's aircraft Daks, Tiger Moths, old Cessnas and Pipers etc. Then airliners, bizjets, military and other GA.

thanks

Rob
