Hi Timbo,
This is a great time to be out in the bush, I spent last weekend doing a 24hr Rogaine at Dwellingup and it was great.
But I'd still rather be in FNQ! Nights were cold.
I've ridden the Mundaring to Jarrahdale section (pedaling) over 3 days, was pretty easy going mostly, Some hills around the dams (Mundaring and Canning) as you climb up out of river valleys. But also many flat or smooth sections that won't burn up too many W/hrs.
A hybrid would be doable, many of the tracks are old dirt logging roads, old railway formations (dead flat), and only very little dedicated single track - nothing hardcore.
You would want knobblie tyres though. Of course a MTB would be better.
Panniers would be good for holding food, clothing, spares and batteries.
You're cutting it fine if you are taking Sept leave and still thinking about battery and bike configurations. I would think about joining you but I'd need to double my battery pack ( or drop back to 48V? Maybe I could go......). I hope you do it, it will be fun.
I grabbed some GPS co-ordinates of the Munda Biddi ride off the web and overlayed them onto google maps.

The two main stops on this first section are Jarrahdale (90km) then Dwellingup (90km) - approx a third of the way each, then 140km to Collie. There some small shops and B&B's, camping, caravan parks at Dwellingup. But if you stay in towns at night (to recharge) you miss the experience of sleeping out in the shelters which are great. There are no other reliable recharge options unless you leave the track and ride into a town.
How do you plan to get back from Collie to Perth? There are coaches, not sure about taking bikes on them. Could ride to Bunbury and train from Bunbury to Perth?
If there's anything I can do to help just ask.
I'm interested to hear your plan, how far you think you can go in a day on e-power etc.
Maybe best to start a new thread, link it to here.
