Hi Bernie
I did the SCT several years ago in Jan with a group of friends. We met one solo walker & a few small groups en route but the nature of the walk does lend itself to having buddies along. Don't get me wrong, it was a fantastic trip but really be aware of what lays ahead of you if you do it alone.

There are rivers, inland & onshore, that need crossing either by foot, rope/cables or rowing.

The Ironbounds is a Mother of a mountain to climb. She can turn really nasty at a drop of a hat. When you least expect it can bring on winds, rains, hail, snow & then just to be fickle bring out the sun again...been there. We had two of our walkers come down with very severe gastro (the joys of bush loos?), one of them over the Ironbounds, delirious & weak. You wouldn't want to be in a position like that on your own...Walking down, hour after hour through the seemingly endless roots strewn track on the western side is both mentally & physically challenging on it's slippery surfaces..had the bruises to prove it!

It is coming into the breeding season for our snakes (all venomous to varying degrees), who enjoy taking up residence in the grassy plains & scaring the b'geesus out of unwary walkers...just ask my friend, who was a blubbering mess after her first two pairs!

You have a few cliff base dashes along the way, if you don't get the tides right.

The weather can be just as unpredictable as the OT & as NickD said there are no huts in which to warm or dry in the unpredictable weather we have here in Tassie.
Don't be put off by my comments because it is beautifully wild & pristine...it's just remote & our lone walker from Belgium nearly turned round & retraced his steps with us after his experiences on the walk.
Par Avion & Tasair take flights into Melaleuca, so if your travels have flexibilty, you could wait until they had spare seats with a flight booking & tag along with that group.
I do hope you get there. It still is one of the best walks I've done to date!
