Is the remains still on the seabed, or was there a recovery of any of it?

Mick. Yes, some parts were recovered. The rest remains on eternal patrol. https://en.m.wikipedia.org/wiki/USS_Thresher_(SSN-593) : "Trieste II was commanded by Lieutenant John B. Mooney Jr., with co-pilot Lieutenant John H. Howland and Captain Frank Andrews, in an operation that recovered parts of the wreckage in September 1964."

One of the most disturbing aspects is that back then, when the reactor scrammed (tripped), the main steam isolation valves automatically closed, and could not be immediately reopened. That killed the steam supply to the main propulsion, which prevented a powered ascent to the surface.
U-tube steam generators have a notable amount of remaining steam inventory in them when a scram occurs, plus there is (reactor) decay heat still available to generate some more steam. If they could have utilized that steam, there is a very real possibility they could have made it back up to the surface, and had time fight / stop / minimize the flooding.
During my time in, that main steam isolation automatic closure/interlock was no longer the case. A hard lesson learned.
The Subsafe program addressed a number of things learned from that tragedy. My boat, U.S.S. Jack, SSN-605 did not get the full Subsafe package, which left some limits on what we were allowed to do.

This tells a bit about Australian sub operations Cold War.
Sorry, but you will have to copy and paste.

Excellent article OG. Both Otama and Orion got a mention. Edward was comm officer and though he kipped on a rack of Mk48s he had a private booth, illegal to search, where the crew stashed contraband to smuggle back into Oz. We saw him and his mates in Sydney a few times when in port at Platypus. They were good lads, all very young and full of p!ss and vinegar. On one liberty in Singapore they got Australian ship liberties banned.. the submariners were renowned as fighting drunks when ashore and another Oz ship, a skimmer, had their liberty stopped because of the way the sub boys behaved. Just young blokes letting off steam after a long patrol. Age shall not weary them nor the years condemn...... On the going down of the sun, and in the morning, We shall remember them. For lost O-Boaters..... https://upload.wikimedia.org/wikipedia/commons/5/59/Oberon_class_submarines_commemorative_plaque%2C_Rockingham_Naval_Memorial_Park%2C_September_2019_01.jpg BTW it's "submarrinners" not "submareeners"

Excuse my ignorance but couldn’t some of the big nuke boats have an escape section that could maybe detach and float to the surface? I’d imagine space is the thing as there isn’t much on them for everything they carry, but some of them are pretty huge.

Only one 'n' in submariner Max. At least here that is how it spelt.
There was only 16 squadrons of RAF fighters that used 100 octane during the BoB. The Fw190A could not fly with the outer cannon removed. There was no Fw190A-8s flying with the JGs in 1945.
