The success of countries like New Zealand, Taiwan, Vietnam and Australia is widely attributed stringent border control, localized quarantine and mass testing when outbreaks occur. I haven't seen any suggestions that the region has a higher acquired immunity to coronaviruses. And other countries in the region (Japan, Indonesia, India and China) had high numbers of infections and fatalities.
