Currently Horizon Worlds is only available in the USA, Canada, UK, France, Spain, Ireland, and Iceland. Now the platform is coming to the remaining Quest supported countries: Australia, Austria, Belgium, Denmark, Finland, Italy, Japan, Netherlands, New Zealand, Norway, Poland, Sweden, South Korea, Switzerland, and Taiwan.

Meta says this "rollout" will begin this week and take a "few months" to complete, so it could be quite a while before users in these new countries actually get access.
