Landowners and Tour Operators
Over recent years, many landowners have had to close access to tracks that run through their properties - and rightly so, because of the irresponsible few out there who leave their rubbish lying around or who chop up tracks by ploughing through in muddy conditions creating heavy and expensive maintenance for the farmers.
Often, tour operators have worked hard with land owners and have gained their trust to take tour groups onto some amazing properties where the average tourer cannot access. There's an arrangement that the tour will be responsible for cleaning up and often assist with property maintenance such as fences and gates. So there's a big bonus for both parties.
Tour Operators can also offer more than just access to private land. One of the major advantages is their excellent knowledge base about the local area and some even focus on ecological activities that compliment the tour guides professional expertise or personal interest.
What I like about these sorts of operators is that for someone that has already marked the "been there - done that" tourist destinations off the list, its nice to have a definite goal for an outback trip. Take a quick look on the internet and you'll find tours that focus on a huge range of special interests from animal research to wildflower cataloguing.
