Johnny,
Everyone else has been sympathetic but I reckon this little adventure is likely to cost you a fair bit, so you might as
well get some benefit from it! Here are a few things to consider.
Rule No 1. Whenever you're faced with a difficult drive, steep up or down, water, whatever, always ask yourself "Do I have to do it?" Never risk the expensive vehicle unnecessarily.
Rule No 2. If you decide to proceed, assess the risks and balance them against the benefits. To do this properly you'll need more information than you can get by sitting in the vehicle. Walk your proposed route. In the present case, get wet. Walk the route and find the submerged logs and the deep holes. Change your route to avoid them, or reassess how essential it is that you do this.
Always assess what steps you should take to prepare the vehicle. For a steep rough climb or descent, or in soft sand drop your tyre pressures to give you a bigger footprint to provide better traction. For deep water crossings, you should also have prepared by extending the breathers on diffs and gearboxes so they vent
well above the water level. (Gearboxes and diffs get hot, so they are vented to atmosphere so that pressure can't build up and force oil out past bearings. When these boxes are suddenly cooled by being dunked in water they suck air in, or if the vent is under water they suck water in.)
You must keep water from reaching the fan. If water rises onto the fan the blades can be deflected forward to tear the radiator to pieces - expensive. If in doubt, wrap a water blind around the front of the vehicle - a strong plastic or canvas sheet from bonnet around the front, and back underneath far enough so that forward movement will stop water rising onto the fan. (Another option is to remove the fan belt, but a blind (bra) is easier.) This is even more important for a petrol vehicle because the ignition system must be kept dry - it helps to spray all high voltage areas liberally with wd40. Obviously you must also keep water out of the engine's air intake - if water gets in here and the engine stops, DO NOT attempt to start it; if you a very lucky you may not need a new engine. Attempting to start an engine which has water in one or more cylinders will cost $$$$.
You are relying on maintaining a bow wave to keep a trough in the water level beneath the engine, so never never stop in deep water. It's good practice to have a snatch strap already connected up before you enter the water if you think there's any risk you might need it.
Which all brings me back to the 2 basic rules - don't run risks unless you have to, and if you must, make a very thorough and
well informed assessment of the risks and benefits. Make sure the gain outweighs the pain.
Not trying to be hard, but, please, learn from this one. Suggest too that you might benefit from joining a 4WD club, one that gives good training. Ours is
Canberra based - if that's your territory, see our member profile for details - you would gain a great deal from such a club. Also, it's good to learn from your mistakes, but much cheaper to learn from other peoples'!!
I'd agree with what others have said about fixing your vehicle - I'd drain and replace gearbox and diff oil, preferably
check and repack wheel bearings. Remove all carpet, floor covering and seats to dry. Do anything you can to dry electricals. From what you've told us, I think you've got off very lightly.
Hope to see you back on the road soon.

Hey Shaker I must agree that's a good idea even though I bought it that way I don't think I will reinstall it there and even more I don't think I will put the car in a situation that will allow water to reach it ever again LOL!
