Japan does NOT have strict lockdowns in place. I know, I work for a Japanese company. Heck they've been giving out travel vouchers for free travel around the country. Not a model for pandemic response at all.
Australia is hardly isolated. Tons of flights in and out every day, and a vital part of the world economy. Really, any country can be "isolated" if they just close the borders to non-quarantined (REAL quarantine) travel, which is much more important than lockdowns.
