Welcome to the CPL Performance question and answer forum. Please feel free to post your questions but more importantly also suggest answers for your forum colleagues. Bob himself or one of the other tutors will get to your question as soon as we can.
When I saw the date, "July 2020", I naturally assumed that I was looking at the latest version. The red text on the left-hand side of the page went unnoticed. Oddly enough, the page did not lead to the current version compiled on 13 Aug 2020.
At first blush, the new Aerodrome MoS removes some of the ambiguity we were struggling with earlier. It is unfortunate that this was done by omission.
It would appear the Australian practice of including the green/brown bit at the end of the runway into the TODA continues, but is no longer a registered ICAO difference. If it is, the difference is no longer explicitly stated in the manual; another omission.
Given that the clearway starts at the end of the TORA, the above would suggest that the STWY cannot be included.
I've been wrong before, and as sure as "god made little green apples", I will be wrong again.

Regardless of the option for a given runway SWY is irrelevant to the TODA. SWY sits at the end of the TORA, regardless of other considerations. If there is a declared CWY, then the SWY sits underneath the CWY. If there is a defacto CWY, the SWY still sits underneath it.

I can see your point. However, the de facto CLW (Australian practice) you are referring to is the 60-90m between the end of TORA and the end of runway strip.
Are you suggesting that all of the STW is a part of TODA or only the first 60-90 m? Is the STW in excess of 90m de facto CLW?
Notwithstanding the above, the definition of TODA is: TODA = TORA + CLW. There is nothing explicitly stated in the MoS or AIP to suggest that TODA includes any STW whatsoever.
Furthermore, there is nothing to suggest that Australian practice differs from ICAO when a STW sits at the end of the Rwy.
I'm not really sure why you are so fixated on SWY in relation to TODA. The former is critical for ASDA considerations but has not much to do with TODA. Sure, it lives under CWY, where that exists, but such is a quite co-incidental consideration for TODA.

I'm a little confused, the inclusion/exclusion of the STW was at the very core of this thread.
It was always my view that the SWY had nothing to do with TODA. You did not agree.

I would hope I didn't give that impression. About the only situation is with a SWY one would expect that, coincidentally there will be a declared CWY extending at least to, or beyond the end of the SWY. If I gave the impression that I was suggesting that the SWY materially related to the TODA, that was not my intention and, for which, my apologies ...
