I'm guessing I won't get too many replies to this one, as I'm certainly not a serious walker. Going back about 15 years ago, I walked Hannel's Spur from Geehi to Thredbo, twice (about a year apart). I didn't have to worry about navigation, as I did it with a mate who was an experienced walker. We watched the weather (forecast) closely, and did the walk in autumn (both times), so the weather was close to perfect.
At the ripe old age of 60, I'm keen to do it again (for the last time), but without the necessary navigation skills, I need some lunatic who knows what they're doing, to come with me! The only other option is to do it myself, using GPS navigation - which I know nothing about (but how hard can it be? LOL). Even though I can't remember the last time I did a "proper" walk, I go running just about every day - I did a respectable half marathon last Sunday. So my fitness and health is pretty good for an old bloke.
The only other decent walks I've done - Bon Accord Track from Harrietville to Hotham (twice) and Bogong. I can't see the point of driving a long way to do an easy walk!
I live in northern Victoria, not far from Echuca.
