An ASX file (Advanced Stream Redirector) is not the source media file itself, but a list of what it should play/stream.
Inside the .ASX file is this...

You might be able to download the file here...
http://202.6.74.140:80/winlibrary/statelinecanberra/201002/r517802_2847458.wmv...but it seems not, they have made it difficult to easily download instead of stream. I'm sure there would be a way to do it, but not sure we/KHA should.
This would still be a low quality version of the video, optimised for streaming.
It would be a better idea to ask ABC, on behalf of the KHA, to supply a higher quality, less compressed, source file, for use on the KHA website and for other KHA promotional purposes.
I'm only new here, so no idea what the protocol would be for requesting this on behalf of the KHA, but I am happy to do it if no one else wants to.
I have asked Stateline for another story in the past, and they would sell it to me, though it would have been free if I was in the video myself.
I would think that they might provide it to KHA if asked officially for it, for website, promotional, and historical archive purposes.
