Haven’t driven it for a few years.
Keep monitoring the road and weather reports. If we get late monsoonal rains or a cyclone the road could be closed into May. There’s currently a couple of metres over bridges around Bradshaw/Timber Creek.
Once the road is open, it’s a fairly straightforward drive.
Things to watch out for are washouts, wandering stock, kamikaze kangaroos, emus (if one runs across the road there’s usually a few more following) and the tedium of driving to the speed limits rather than the conditions.
Depending on car and driver, Broome to Kununurra can be a day trip. Same with Kununurra to Darwin. Otherwise, Fitzroy Crossing Resort may be a mid-trip stopover. (It’s been a while since I’ve visited.)
Fuel stops are adequately spaced. Just plan around your car’s mileage capacity and leave some in reserve.
And if you’re not used to sharing the road with road trains, they’re longer than you think, so don’t rush things.
