"Some locations (Japan, Singapore, Australia and Hong Kong) have managed to avoid exponential growth despite having a large number of cases."
Probably due in Australia to the heterogenous population density and rather low number of infections to date ... but that could easily change in the bigger cities ... while density is proportional to N the proportion of encounters goes something like N-squared (where N is the population).
Singapore, Hong Kong and Japan were able to artificially reduce their effective density ... to reduce the encounter rate. Australia can try to do that too in the bigger cities especially!
