OLT clothes for September

Hi all. We are heading off in a few weeks to walk the OLT for the first time. I'm struggling with deciding, from my mild Queensland home, what I will need. I feel the cold but hate that hot sweaty feeling while walking. I have a pair of Macpac softshell trousers I was planning to walk in - I figured they will be tough and a bit water and wind resistant if drizzly, and also warm. Does anyone else walk in these? Do you think I will get too hot?
My nightime plan is dry merino layer, 100 fleece top, fleece pants, down jacket. Enough?
I am a chronic overpacker but don't want to be carrying a whole heap of extra stuff I will never use. Thanks for any advice!
