I wrote the following a good few years back about walking on private land, which I think is useful for your question:
https://fatcanyoners.org/2013/02/26/pri ... nd-access/I don't do a lot of walking on private property. Most private land is at the very least grazed, and the idea of walking through glorified paddocks doesn't excite me, especially when about 10 per cent of the state is publicly accessible.
There are many areas of public land that can only be accessed (or only easily accessed) via private property. Over the years I've gotten reasonably good at negotiating access to these places, with only a couple cases where I wasn't able to arrange it.
Techniques that have worked for me include:
- online searches (some bigger farms have websites or social media accounts) or you can find the name of the property owner and look them up in the white pages (farms often have landlines because of limited mobile reception)
- talk to other bushwalkers who have been to the area and ask how they arranged access (or try any local bushwalking / outdoor clubs)
- call the local pub. Publicans are often helpful and have a good knowledge of the locals
- talk to the local real estate agent
- call the local RFS brigade
- call local community groups (progress association, historic society, even country womens association). People involved in those groups often know lots of people.
Where possible, it's best to reach the property owner on the phone. Many are a bit cagey and want to know what you're planning to do. I've had several tell me they've had to chase illegal hunters off their properties, and other people up to no good.
When I get out there, I always drop in to the farm house and introduce myself as the person who spoke to them on the phone. I tell them again where we are going, ask where they want us to park our cars, and tell them when we'll be leaving. I also knock on the door once departing so they know we are safely out.
Personally, I often try to leave a six pack of beer. It's a simple gesture that shows we're genuinely thankful for their assistance. Hopefully the positive experience also makes them more likely to allow future people to cross their properties.
There's plenty more, but the main points are to put in the effort to get permission (don't try and sneak across private property) and be courteous and respectful. For me, it's actually a fun process trying to track down the landholder and get permission. You also get to pick their brains, and many have useful tips about the local conditions, such as how dry it is, and even advice on where passes are etc.
