There are a number of tours you can take from Perth and Broome to see some of the more spectacular sites such as: Windjana Gorge, Tunnel Creek, Cape Leveque , Bell Gorge etc
These tours may be just tours by bus, boat or by small aircraft.
We saw a lot of these around the Kimberley. It seemed a great alternative to the caravan and it did have the added extra of being a 4WD.
One gentleman near Tunnel Creek allowed us to have a look inside. He recommended on reflection that it would have been better to have had a collapsible roof as the hard top did make the car "top heavy".

How to get to the Kimberley's? Well, the most convenient way is to fly into Broome from Darwin, Perth, Adelaide, Alice Springs direct. From the east coast of Australia, you may need to make a connection at one of these places. I suggest join a 4WD tour of at least 1 week, and enjoy! Some tours also leave from Darwin, so that could be another option as there are many more flights into Darwin from all over Australia as well as Singapore, Hong Kong, etc.
For the more adventerous, you can drive, but to get the most out of The Kimberleys, it's best to have a 4WD motor vehicle. Expect to take days to get there from most parts of Australia!
An idea how remote this part of the World is, here are the approximate flying times into Broome from the selected cities:
Perth - 2.5 hours.
Darwin - 2.5 hours.
Adelaide - with a connecting flight, about 7.5 hours.
Sydney - with a connecting flight, about 8.5 hours.
Be warned that there aren't many flights into Broome from many cities other than Perth, so booking early can be at your advantage.
Another option is to join a tour in Perth that will also take you up to The Kimberleys. One of the popular routings is Perth to Darwin via Broome and in reverse. Many companies offer these tours.
Be extra careful along the roads especially when the sign indicates "straying stock". What it means is that there is cattle wandering close to the roads. There are no fences protecting them! Have a look at the video to get the idea.
