Purnululu NP and Mornington Wilderness camp

Can I also add, take heed of the road signs.
If it says there is a Dip ahead, then there is a dip ahead so slow down early.
Safe travels

Hi Ania

The Pajero will be fine for your trip. The vehicle should be normally equipped with a spare and a jack but check when you hire it

1) The most important thing is that Britz know the roads you will be travelling on with that vehicle...some hire vehicles are not equipped or allowed to travel the GRR or the Bungles

2) Some hire companies do supply some of the recovery equipment that you have listed...you need to check so you don't waste money purchasing items you don't need

3) As for spares the minimum I suggest you carry is at least 2 spares of which perhaps only one needs to be fitted on a rim and that would be normally supplied with the vehicle.... Perhaps try and purchase a 2nd hand casing from a tyre company if the hire company wont supply a second one for you

4) I am assuming you will be only staying on or near the GRR and in/out the Bungles and so considering you will be flying in and out I would keep the expenditure to the basics as the chances of you requiring the serious recovery equipment is very unlikely (straps, winch snatch strap shackles etc)...so to avoid wasting money on items you cant take home or recover your costs on I would take with me the following

* spare 2nd tyre ...on a rim if possible but at least a 2nd casing and a fellow traveller may have the tyre levers to help you change onto a rim if needed
* a tubeless plug repair kit...assuming the tyres are tubeless.... ( get a decent one ARB or similar that is not a cheap plastic handle that wont have the strength to insert the plug into a 4WD tyre
* a compressor...don't spend too much on this you may not use it or if you do you don't need one that is very fast....just one that pumps air
* a long handled shovel/spade
*Jerry cans.. number for you to decide once you know the fuel tank size and the longest distance between fill ups....(not a lot of options on the GRR)...also never use your last one if you can help it....a hole in the fuel tank from a rock can happen...if it does make a paste from soap and fine dust and plug the hole and let it harden.
* water...make certain you have plenty of drinking water per person
* sunscreen and hats and personal drinking bottles...some of the hikes into the features are longish and you can dehydrate easily
* a handheld UHF would be handy but not essential
* If you are not careful you will spend a lot of money on recovery gear you may never need and have to leave behind when you fly home
* take plenty of common-sense...a good sense of humour...fuel, water, spare food ...interact with fellow travellers...don't be afraid of asking advice and help if you need it....as long as you were well prepared and didn't bring any misfortune on yourself by being under prepared and take silly risks then any fellow traveller will stop and help

Ania... your proposed journey is not really into isolated country...there will be other vehicles travelling the same time and often each day..........apart from running out of fuel your most likely trouble will be rock/stone damage on your tyres......so keep your tyre pressures lower on the rocky country so the vehicle doesn't shake itself to pieces...slow down and drive according to the conditions and don't spend a fortune on recovery gear that you most likely wont need....I carry all the spares and recovery you can think of and have travelled the roads you are talking about several times and never even had a puncture or a tyre issue...but others are not so fortunate

enjoy......

PS.... if you intend crossing the King Edward River and travelling to the Mitchell Falls...then those of us on this site may add a few more comments to what we have advised so far

Hi Ania,
As mentioned in the posts so far the areas that you will be travelling through are generally busy, however that being said the area is still isolated and does not have many vehicle services.
When we have hired vehicles in the past the information provided to you by the hiring company is generally quite inadequate to cope with some of the conditions that you may find. In particular the issue of tyre pressure must be considered. Of course if you are lowering and then raising tyre pressures you need a 12 volt compressor. You can usually hire these from the car hire firm.
The nature of the tyres on your vehicle is also worth noting. Light Truck (LT) tyres have much stronger sidewalls. Having stronger sidewalls means that pressure can be lowered more safely to cope with the corrugated roads. If you ever get bogged in sand, probably unlikely on your trip, lowering your tyre pressures will probably get you out. You can often hire a recovery kit. When we hired a recovery kit we used it to pull others out of a sand bog.
Hiring a satellite phone is worth considering as mobile coverage out of town centres is problematic. If you intend to use your mobile make sure it can connect to the Telstra Next G network. A UHF radio can be helpful but its distance coverage is generally between 5 to 10 km at best.
Mitchell Plateau is well worth visiting , however when we visited in 2013 the road from near King Edward River to Mitchell Falls was extremely corrugated. This is the road that causes most vehicle damage. Again to lessen any chance of damage to your car lower tyre pressure and speed is essential. The King Edward River crossing can be interesting.Check before you head out that way.
I have heard that the Imintji Roadhouse is no longer operating.Check this out before you leave.
If your vehicle is petrol powered rather then diesel take car carrying fuel. As suggested calculate your potential fuel usage and relate this to refueling points.
Temperatures can be quite high throughout the region. So prepare yourself as suggested.
Have a great trip.

Here you go Tom:
Europcar terms and conditions of rental

Yeah perhaps they should get their answer service to read it but to be fair on website it is different

Hi Ania,
It is odd that the hire company said you cannot travel on the Gibb. We have hired 4wd Toyota Landcruiser camper vans and there is no problem taking them on any public road, sealed or unsealed.
With respect to pressures with our fully laden 200 Series Toyota Landcruiser towing a campertrailer I would run 50 psi rear and 45 psi front on bitumen. I do have light truck tyres so they are less easily damaged on the sidewalls especially when running low pressures. On good unsealed roads I run 30 to 35 psi rear and 25 to 28 front. These pressures are measured hot. Speed limited to 80km/h. If I have to lower the pressures further I would restrict my speed to 60 km/h. There is a rough rule of thumb which states that if your tyres increase in pressure by more than 4 psi after you drive for a few kilometres then the pressure is too low. A discussion of the rule can be found here, http://www.aawen4x4.com.au. The key is to check your tyres frequently with your hand to ensure they are not getting too hot. Of course with lower pressures you must restrict your speed.
Not sure where you can rent a sat phone in Broome. A search on the net will probably turn up something.
Enjoy your trip.

I'll go out on a limb here but the two routes you are travelling are pretty well travelled and I don't see a great need/benefit for a UHF radio. The area you are travelling is quite hilly and UHF signals are going to be restricted by the terrain in many parts.
