You need to be more inconspicuous about setting up your location.The Ka band antennas are easy to hide inside a small box or under a newspaper,etc.I always keep the control module well hidden,too.
Here in the USA,citizens have a right NOT TO BE SEARCHED unless the LEO has probable cause first.If the LEO can not see anything visible (like a firearm,laser pen,illegal drugs,etc.,etc., he has no right to intrude or ask probing questions if no law has been violated.
I never give permission to search myself or vehicle or answer questions either.The U.S. Constitution is my protection against LEO bullies who attempt to intimidate me w/ these kinds of tactics.

I'm not familiar w/ the Laws of Australia on this subject matter.

They generally do what they like, if they suspect anything.

Police can carry out a search of your person and property, your place or your vehicle at any time with your*consent. However, police also have wide powers to carry out a search without your consent and with or without a warrant
