I read that in Australia there are a total of 2,200 ICU beds for the ~25 million population. As a result of COVID-19 they're increasing this number as much as possible, but if the infection rates continue the current trend, then there are going to be large numbers of people dying due to the lack of resources.

  18 in 500,000 is 0.00366%
  2,200 in 25,000,000 is 0.0088%

More than double, but still likely to be woefully inadequate.
