Wow, that is a long time and I guess it could take that long to procure a vaccine. Our PM's have been talking about a Trans-Tasman- Travel- Bubble but that's sometime into the future. It would definitely bolster tourism.
Most of the Pacific Islands locked down their borders early and have got on top of Covid (some didn't get any cases) so travel may be possible there too in the near future. People would still have to quarantine for 14 days when entering the country.
