Covid is different to ordinary infectious diseases even most serious ones.
Bacterial infections you often are able to identify the bug and antibiotics that are the most apprpriate.Sometimes the disease- eg pneumonia where the bug can't be isolated there are well known protocols for which antibiotics should be used based on the severity of the pneumonia.
Diseases such as TB,HIV etc have also accepted treatments and proticols.
With covid it is still a work in progress.Certainly there have been incredible advances but still a lot more to learn.
As to which hospitals it depends on facilities,staffing levels and the expertise and experience of the staff.
For example the largest cities outside of Adelaide and Gawler are Mt.Gambier and Whyalla.I have worked at both and won't go back as it is too dangerous.Especially Whyalla.When I worked there I was the only physician for 5 days of the week covering Whyalla,Port Lincoln and Port Augusta.At the time when I worked at the NWRH which had less population than Whyalla I was one of 4 physicians and there were also recognised Intensivists and FACEMs neither of which were in Whyalla.

@dajop 's list in Tasmania both Launceston and the Mersey hospital treated more patients with covid than Hobart.The LGH has an infectious diseases physician who is one of the ATAGI team.The Mersey hospital has a physician who had an interest in infectious diseases.In February 2020 he anticipated problems.He got the hospital to order large supplies of sanitiser,also limited hospital entrances to 2 during the day and 1 at night.He also alerted businesses and even distributed sanitiser to the districts service station and gave advice on cleaning the pumps.He ended up treating 14 patients,all over 80 with multiple co morbidities.They were admitted there as they were expected to die.9 got out of hospital.
In QLD Townsville would be a definite starter.A well staffed hospital with all needed facilities.Deals with a huge referral area.
