With regard to height restrictions and the operation of the "Can I Fly There?" app I queried CASA yesterday and they promptly replied today.
Good morning Rob
The ‘Can I fly there?’ drone safety app reflects the standard operating conditions for those flying their drone commercially (under the excluded category of commercial operations) and should be used in conjunction with the Standard Operating Conditions that apply to the category you are operating in. For further information on this app please read the information at
Can I fly there? - Drone safety app | Civil Aviation Safety Authority
In your case, as you are operating recreationally, you must comply with the rules listed on the CASA website at
Flying drones or model aircraft recreationally | Civil Aviation Safety Authority
If you are a recreational user (flying for fun) it is possible to operate above 400ft AGL in Class G airspace however you MUST be able keep the drone within visual line of sight and ensure you do not create a hazard to other aircraft.
Advisory Circular 101-10 is not aimed at Recreational users, it is for those operating in the excluded categories.
Advisory Circular 101-3 was issued in July 2002 and is currently under review to take into account the changes to the regulation that came into effect on 29/9/2016.
Please let me know if I can asssit further.
Kind regards

Hope this helps those like me who up until now thought that the 120m AGL was an overall restriction. BTW Class G airspace is uncontrolled airspace.
