Was it a house in residential or rural property? Its been a while since ive flown to maryborough, could have been some guys out spotlighting and you were scaring away whatever they were shooting so u were the next best thing.
Or it could just be kids... or drunk adults acting like kids
If you can identify the house from the air and figure out the address just send the coppers around to have a chat with them.
You might have to explain what the dangers are to the coppers, but make sure you talk very slowly and spell the big words out for them so they understand...
Better yet just write out what you want them to say to the people at the house...
