it was reported that ABC Northern Territory Shortwave Services left shortwave for good.
I asked them and they replied they will be back on coming Tuesday:
Dear Mr Kuhl,
Thank you for your note. The service you are referring to will be re-established next Tuesday morning at 9am local time.

Thank you Harald. I, too, have seen a lot of notices on social media that the ABC Northern Territory Shortwave Services had shut down permanently. I had not posted anything here because I couldn’t find any mention or confirmation from ABC. Looks like they’re probably doing routine maintenance.
