First contact local council or land owner and get the dates for the baiting days on private land in that area. You may need to contact national parks for their baiting days as they are most likely different to council. This will then help you figure out how you hunt and when you hunt. If your private land owners don’t bait but national parks do then ask how they bait? Is it by vehicle or aerial baiting? How much bait gets put out? Injected or rolled? If put out by hand along the roads through the park the rangers might have have a policy that they visually check the bait to see if it’s gone.
