According to user reports, it appears that Google One has since expanded its availability where it now covers a variety of countries which includes New Zealand, Taiwan, Singapore, Czech Republic, Chile, Poland, the Netherlands, the UAE, Lebanon, Egypt, Indonesia, and Belgium. If you live in those countries, you can head on over to the Google One page and you should be able to subscribe.
In terms of pricing, this will vary slightly from country to country due to the exchange rates, so it is possible that it might be marginally more expensive in some countries than others, although like we said, it will be marginal. In terms of pricing, Google has priced the 100GB tier at AUD$2.49, the 200GB tier at AUD$4.39, the 2TB tier at AUD$12.49, the 10GB tier at AUD$124.99, and the 20TB tier at AUD$249.99. Note that these are monthly subscriptions and you’ll need to keep paying for them if you want to keep your cloud storage active.
