Thank you, all this info is very useful.
Big question: how much off-track walking have you done?
Hard to quantify, but not too much strickly speaking.
Usually parts of track in open terrain (which seems to be the case with Frankland range) without a path, walking along the ridges on peaks / smaller mountains, following loose set of cairns, occasional route-finding to peak, stuff like that mostly in New Zealand, but not really cutting a path through dense jungle with machete
If possible, hire or borrow a kayak to get to and from Frankland Shore. I'm prepared to give you more exact route details if you're going to go that way
Don't have experience with kayaks, and I am way more comfortable with walking on dry land than getting wet if possible, but that going around the corner to the Frankland shore is a good idea, I would welcome more route details in case I decide to give it a try
pps: Secheron is an interesting choice for a fixation. I had one myself for decades due to old personal history, but I am wondering from whence comes yours ...
It is a bit silly, but nevertheless...
I am working for a company of that name (Secheron) in Europe and it is hard to say when I will be in this area of the world next time, so it seems like a nice opportunity to climb it and maybe do some "flag-raising"
So the "bare minimum", just for the fun of it, probably would be a picture of that peak, which should be covered from Red Knoll
