An article in the SMH today introducing a "Great Southern Walk" which the NSW government are planning to announce funding for in the state budget next week.

It looks like it mostly follows existing tracks between Botany Bay and "Southern Gateway Centre" (which is a bit south of Sublime point).
There's a map in the article which includes possible accomidation sites and view points.
Interestingly, "accomodiation" (which I assume = glamping, or maybe even something more?) is shown at both Garie and Wattamolla, where it currently doesn't exist. Madden Plains is bracked as "possible accomodation site" and there are already existing camping at Bonnie Vale, although no public cabins there.
The long awaited draft Plan of Management for Royal NP is currently on exhibition and as far as I can tell doesn't take this iniative into account, let alone accomodation at Garie and Wattamolla, so will be interesting to see a detailed proposal of that they plan do do.
Also, from the map (but not mentioned in the article) they might be making use of the old Otford to Stanwell Park train tunnel. This would be great if they do, as it's a pretty unique feature and would benefit from being easily publically accessible.
Overall, I don't have too many concerns about the proposal, mostly just what form the in-park "accomodation" takes at Garie and Wattamolla. Also, the Coast Track comprises a large part of the route, and it's already very busy. I'm not sure it really needs extra attention! The main problem I find is that the new elevated walkways that have now been installed for much of the length are relatively narrow and it can be a little tricky in places to pass people who are coming in the other direction. Making it all "dual carriageway" width would help reduce this problem.
Finally, the article mentions a "second multi-day walk will be announced in the coming months" which I'd be keen to learn more about. Just hoping they stay away from the wilderness. I'm not sure what level of community consultation is involved with these sorts of proposals and they generally seem hard to stop once in motion, so lets hope what they are thinking is appropriate!
