Rex incident YSSY
Depends on your interpretation I guess. Did the prop adopt a horizontal attitude immediately on departing the engine, a'la a helicopter rotor, and residual thrust then push it up and over the wing?
I reckon some of the posters have got lots of egg on their collective faces. the Tim Hamilton I know is/was a commercial pilot with a lot of twin experience, has held management positions with second tier airlines and an owner of a high performance single. I'd suggest it's the accusers that are the trolls - just saying...
And you reckon the womble posting here is one and the same? I reckon my complexion is just fine sans egg, thank you. I note that the mods on Rumours and News lost patience with his drivel quick smart and binned the posts within hours.

Don't know this system but if on fine pitch stops at time of depart - the prop would be in full fine. If in normal operation it will be off the fine pitch locks/stops and after depart head to either full fine or feather (depends on design) but it is a long time since props were designed to go full fine upon oil failure.
So to find the prop in a feather position seems normal to me.

Composite prop and tuff.
The crew did well under unusual circumstances. All souls safe. That is the best outcome.
I hope they are sleeping ok. It is tuff after any incident.
Take care out there.
All of the entire propeller assemblies I've seen that have disconnected from a Saab 340B in flight have looked just like the one in the photos.

A genuine question BTW.
Just the one!
But seriously: Why would anyone be surprised that an artefact designed and built to withstand the kinds of forces endured by a propeller assembly like that look in pretty good nick after it disconnects and falls to earth?

“Interesting to see that the prop was already feathered when it departed the airframe”
Does that mean –
1. It was feathered immediately before separating and if so pilot did the right thing continuing to KSA
2. Was feathered earlier on in the flight, where a diversion to a closer suitable airport (Wagga Wagga/Canberra/Goulburn/Camden/Bankstown) should have been considered/done by PIC
Interesting.

Seems to me to be very, very odd that out of the bolts that are visible, only one has a nut. Others appear to have a washer in place and one appears to have snapped off. The visible threads seem 'clean', as if they have had nuts driven on them relatively recently. The plate shows signs of washers having been in place.
I would find it very, very difficult to believe that there should not be washers and nuts on all those bolts, or that they were there and somehow wound themselves off after the propellor departed the engine.
Hopefully the ATSB report will shed some light on whether this is normal.

Most intriguing, are the missing flange attach nuts cause or affect?
Why can I see the letters FA on the broken tube?

Missing nuts
That prop flange was removed by the ATSB recovery team before the prop was transported to the bat cave. I suspect the photos/video we're seeing were taken during the removal process.
