Hi Graham …. Here is a small snapshot of my 50 years of association with the largest parallel sand dune desert in the world, “The Mighty Simpson”. I crossed that first sand hill on the western edge of the desert just as you have done in this video, but back in about 1975. I remember I was also full of excitement at tackling the unknown terrain which lay ahead plus there is always that added dose of adrenalin which comes with any solo vehicle crossing of remote areas. However a challenge which would well and truly surpass that moment came in 1985 when at the age of 51 I landed by light aircraft on a clay pan nearby and then took off pulling a two wheel cart loaded with supplies and headed east - solo - no backup vehicles, destination Birdsville 400kms away. At about the half way mark using rods that formed part of the structural strength of my cart, I drilled down about 12ft and located enough water to replenish my supply which was by then down to one last drink. It could be said I was desperate at that stage and starting to feel the effects of forced water rationing. About 50kms further on I abandoned my cart on top of a high sand hill and took off into a cool moonlit night by compass for Birdsville which I finally reached after about three weeks of desert travel. Sorry, I digress from the main thrust of this video, that of reaching the marker at the Geographic Centre of the Simpson Desert and trust that at the age of 86 you will cut me a little slack if I tend to wander. Tracks and the gentle westerly slope of the dunes, although at times rather bumpy, presented you with a relatively easy challenge as you state until you reached a point where you had to deviate to the west for about 5km to reach the Geo/Centre thus forcing you to confront the steep easterly face of the dunes. Your dramatic commentary and visuals highlighting the numerous failed attempts by all is testimony to the fact that this is not a challenge to be taken lightly, even with so many vehicles available to give assistance. I have an admission to make. After some seventy/eighty desert crossings by vehicle from all different directions, walking across it twice solo - west to east and north to south without a backup vehicle - and having ridden camels over it, I have never actually visited the site of the Geo Centre now marked officially by the tower and other paraphernalia. It was back in 1977 when at a point on the Eyre Creek 60kms north of the SA border (Dickerrie Crossing), I managed to ford the then flooded creek. I was on a mission to tackle what was thought to be impossible back then - a trackless solo vehicle crossing of the Simpson Desert east to west while climbing the steep face of some 1200 odd sand dunes and traversing some 350kms of untouched wilderness. I was driving the baby Suzuki 4x4 LJ50 soft top heading due west by compass (no GPS then) and it wasn’t more than a few hours after departure that I fully realised the enormity of the task I had set myself. I don’t wish to bore you with the day to day challenges as I am sure although your experience was limited to about 5kms you would be well able to guess. Suffice to say there were many spectacular failures, multiple attempts and frightening situations with the vehicle rocking gently ready to roll back to the bottom and endless days consisting of never ending battles against a formidable enemy to be fought and won. I passed a few kilometres to the south of the Geo Centre, not marked at that time, and early on day six I encountered my first sign of man's intrusion into this unique area. Nestled under a bush was a rusty heap of tin cans and then a few hundred metres further on I finally reached the Colson Track. At the end of day seven after some 350kms I finally exited the desert having now proven that an east to west crossing is indeed possible. Thank you for the video - your camera and drone work is excellent and I look forward to your next desert trip as through them I am able to live my past experiences throughout this great country of ours.

I would love to see them do a special where they come here to America for a few episodes. Maybe a day in the Rockies, day in New Mexico, a couple days in Alaska with a great American off-road crew. Then the Americans go back to Australia with them and film 3, 4, 5 episodes in Australia. I have never seen an episode of this show I didn't really like.

Absolutly loving it.....but need to say there is no 4wd action without SHAUNO..

I always feel a little bad that we don't get to see more of the camera guys, do you guys have a video, behind the scenes like about how the camera crew keeps up and sets up their equipment?

Just watched this again. Great to see a totally different perspective of off roading. And no camper trailer!

Great episode but I’m missing Chef Shauno lol

Well done 4WD Action. You've shown a piece of Australia most of us will never experience. Thank you.

4:20 The longest Seismic (shot) line I worked back in the 70s was 498 km long. It went from just North of Barcaldine to the dunes West of Diamantina Lakes if I recall correctly. Some of the country we went through in those days was just unbelievably stunning.

FINALLY Graham’s gu on 4wd action

Stuck here in the flatlands of Germany with my trusty old 4-Runner from California,, no ocean in sight... I can't thank you giys enough!! Fking awesome, keep up the great work!

Thanks for another episode boys, its always appreciated. You guys really need to get a netflix style service going so people can get all the episodes.

Hey Graham, Just wanted to tell you how much I am enjoying all of your videos. I just discovered your channel about a month ago being home on disability with a herniated disc in my back! Needless to say I can’t go camping or four wheeling so I am getting my fix watching guys!. The amount of varied terrain that you guys have in your country is awe inspiring! Keep up the amazing work! I look Forward to every video! Greetings from California.

Sitting down with a cold beer next to the pool watching 4WD ACTION, not bad. 👍👍😂

I love your regular episodes on the well-traveled tracks, but this was something special. An epic trek in the deepest outback. Well done.

4WD Action, thank you very much for the free episode. I'm just curious, I've been hearing that Australia is going through some really bad heatwave, hope you guys are keeping cool down there, greetings from across the Indian Ocean, Nairobi Kenya.

Another great happy hour of my Friday

Awesome timing, planning my trip across now for a trip midyear. Legend!

4wd action have made it to trending #13 , keep it up lads !!!!!

"don't try this at home type of track" 😂yeah because we all got a Simpson dessert in my back yard

What an adventure, what an expedition. That was an epic film. One Life, One Search, Shane

Good to see Graham back in the GU, but where’s Shauno??

Competence, preparation, and big brass ones. Yep. Your episodes are getting better and better, Graham. Well done from Seattle.

My fav channel on youtube. Hello from the southern USA! keep up the awesome content!

OMG it looked like you were all trying to drive over a water bed the entire time. Totally Epic, thank you everyone.

What a awesome interesting video.Your commentary and all involved comments along the way made it wonderfull viewing.Proves not a trip for dreamers and novices. Thanks again guys

That mea was a feast and the presentation, well it beats Shaun's meals visually! Graham with that awesome dune action!

loved it.. is good to change the usual format and team from time to time...great adventure! and great GU Patrol.

Having done the simmo last year - this footage does it justice. Great videos team! Keep up the good work.

Lots of gidgee (sharpens chainsaw) around for fire wood (resharpening chainsaw) which is great for camp fire cooking... It's just hard as an old boot!

Great trip. Miss Shauno. Absolutely to much fun.

That's rad...The Nissan is back...So good to see it again...Need to see more of it...👌🍻...

in my opinion best episode of 4wd action

There is a visitors book in the centre of the desert?! Amazing! Would love to read some of those entries :)

Said it Before and I will Say it again!! Best 4 wheel Drive Show on EARTH !!!!!! Love It Guys!!! Thanks... :-) :-) :-)

Great! So well filmed and narrated.

awesome video...mate... absolutely loved it every minute of it

Awesome work Graham and team. Cheers

That was tops, that last sunset on their faces, red to the West and purple to the east. Lots of memories like a tribal man standing on a ridge in the Gibson desert looking down at us one leg up leaning on his spear. I often wondered what he was thinking. 50 years, all seems so very long ago.

Love it! Always awesome stuff!

EcoMuse. Modern day Malcolm Douglas. You're fantastic to watch Graham. All the best mate.

I'd love to know more about the VW hubcaps on top of the central marker pole 47:54 - Probably a Kombi made it out there first! LOL

Amazing guys, absolutely amazing!

Nice video once again. Thanks!

Graham when you guy's are out on the trail you defiantly eat well. I'm jealous of some of those meals.

Epic journey graham, would be an amazing trip.

The camaraderie amongst the fellas is amazing...

What an episode!!!!!! Watched it twice...

Awesome trip guys. Need to post videos/pics of the night sky out there though! I imagine it would be amazing

Looks absolutely amazing, would love to go here and have it on my channel

Cheers Graham. As always a well informed video.

Love to see the GU it's looking great!

One of those bucketlist trips I need to get organised. some techniques with the cameras I need strive four in my videos.

Awesome video, Loved it. Have to go Simo

Yabbadabbadoo, a vid with the Patrol ute, Graham its what we have all been waiting for!!!!!!

best video yet, cheers

Graham shouldn't be worried my great uncle was the person who found the geo centre of Australia in a convoy of 6 old land rovers without any shot lines to follow just a hand drawn map and a not pad

Just when you think you've seen it all; some bloke pulls a whole BBQ out of the back of his rig in the middle of the Simmo haha 👍

Love your videos and this one was different for sure. I couldn’t help but notice that you often didn’t have your lockers on. Was there a reason? Was that to take it easy on the axels? Epic Adventure thank you for the experience of getting to the middle of the desert!!!

Great video guys!

I’m getting Emu War flashbacks how dare you!

just got home. thanks for the upload. :)

Well, so glad I just bought my first 4B. Mazda turbo diesel, 3inch lift. Now who wants to teach me. I know it's always safety first. No tow gear, nothing to go anywhere. Pensioner rates everywhere. But a $2000 awesome purchase. Any words of wisdom apart from stay at home. Tamworth NSW.

Graham, this is best of the best, at least for me.

WOW! Just Wow! You guys rock! From Colorado Springs, CO US!

Amazing as always!......but I missed Shaun and Jacko:P

I reckon you guys need a bloke in an old HJ 47 ute to come along on your next trip. 🙋🏽‍♂️. Hands up and waiting for the call 😂😂

Ive been Impatiently waiting to see Graham's GU on the show 😄

Just in time for Australia Day. Nice one.

This is a great channel guys!!

An episode about the camera work etc. would be great. The closest I have ever gotten to where they went is Leigh Creek.

Good on you guys. Great video, showing the real Australia to the world. It would be been great to interact with the countless Aboriginal communities you guys would have passed, to get some local knowledge. A lot of the time, there are great stories about the origins of some of these landmarks/topography and that knowledge can be very useful.

Awesome vid guys......4wd Action should come drive our dunes here in Namibia :)

Good drive guys. I know of some very challenging 4wd dracks near we jasper nsw

Shauno might have to lift his game lookin at those meals. Another epic trip

Good Video Mate

Epic trip to say the least. Couldn't have anything nice like that without vandals here in the states. Graham, tell me about that bush knife you had with you!

Great episode!
