Not really a very good comparison.
Australia is most definitely not a regional country as we are more "urbanised" than nearly all other countries on earth with about 90% of Australians living in 0.22% of the land area. The majority of Australian 100 or so COVID19 deaths have occurred in Melbourne and Sydney, with cities of 5 million plus.
Australia with 25 million people has has fewer COVID19 deaths than about 40 of the 50 US states.
The 10 or so US states with similar or fewer numbers of COVOD19 deaths than all of Australia all have populations of about 1 million or less.
The total deaths for these 10 states so far is currently about 625 and they represent <10 million people.
Australia at about 25 million including 5 cities of more than a million people each has a total of about 100 deaths.
