Victoria Duck Shooting

Hi
We are In Victoria bird watching/ touring in our caravan.
We are in shock because the duck shooting season started yesterday and we
have found ourselves right in the thick of it.
Last night we had to move on to a new location because we were concerned
for our own safety.
There were rednecks with shotguns in full army greens all around us.
How is this sort of behaviour allowed in Victoria?
More like Bagdad or the USA deep south.
Cheers
Cliff
