Australia has finally released their policy on lane guidance in Australia in this newly released wazeopedia wiki: https://wazeopedia.waze.com/wiki/Australia/Lane_Guidance
There has been quite a lot of cautious delay surrounding this decision, however the USA has served as a test case without any major concerns. As a reminder, lane guidance with voice-support is now available in the production Waze app and is available to all users without restriction.
As always, this is a new feature, tread carefully, always ask questions and engage with your peers. Happy mapping everyone!
