I know this was ages ago, but I was only watching to see you tackle Yardie Creek. I'm stunned you made the call to drive all that way back in wrong direction over corrugations just to avoid that depth of water for 20 metre, makes totally zero sense to me. Worse case scenario, wait for the tide to go out, what was the rush? My Patrol weighs much more (yes SSM GVM Upgrade), just go to 8 PSI and it would have floated across. Nolan Brooke FNQ, go through that, water over the bonnet (car bra in place) it just walks it, it's all about tyre pressure and the correct tyre pressure, not 25 PSI. Salt water is so over dramatised, only vehicle I had rust appear on was our Toyota 76 series. Sons Hilux, rusted chassis radiator support, but that just Toyota's poor build quality, 2 examples here. Previous Jackaroo has had salt water over bonnet on K'gari at Eli Creek, so has Toyota, both Eli & Nygala Rocks, waves going up side window glass. Our current GU has been to K'gari many times, you'd never pick it other than ARB's paint matched bullbar, yes it's rusting in the winch cradle but I'd expect that, have zero confidence in ARB product also now. Hope I've given you some confidence to try again another time. Oh, stop driving like that, huddled over steering wheel, if you blow a tyre, but a Roo, wombat whatever you'll have absolutely zero control.
Probably couldve made it through if we were really keen, or had another car with us. But getting stuck in tidal salt water is a fair bit worse than if it was just a fresh creek!
