If you go to TripAdvisor, you can find a somewhat list.
You have to be cunning in the search.
A lot, I would say all of the Accor hotels have jumped onto the quarantine hotel list, making them lots of money, but then it makes them have a bad reputation, but they don't seem to care.
The Aust govt and state govt, also don't care, who ever decided to use hotels in the first place for Covid quarantine was very inept, stupid, really, but no one ever listens.
From the very begining, they should not have not used hotels, because people like us, who don't have the Covid disease, any strain of it, can now get a change of getting it.
Like they are now using the Covid jab as a requirement for travel, despite some being anti vaxxers.
They would probably use Medicare records to do it, like the bowel screening test once you are 50, no way to avoid that package being sent to your home post box.
Marriott Sydney
Swisstotel Sydney
Sofitel Sydney
Pier One Sydney
Park Hyatt Hickson
That is just an adhoc list that I picked up from reading news articles.
Would not be surprised if every hotel in Sydney has already been used for Covid quarantine, but dues to privacy, no list is made publicly available.
Edit:
No doubt. And in the process wasting the time of those trying to check room availability.

...I suspect the absence of any comment would be because they don't want to be stigmatised when their stint as quarantine hotels stops
Some people who have stayed at these quarantine hotels, are very proud and have even gone as far as thanking people who have made their stay "comfortable".
As I mentioned above, just read "reviews" on TripAdvisor Aust website.
