New australia time
You're referring to the new time zone in Australia!
As of October 3, 2015, Western Australia (WA) adopted a new time zone, Australian Western Standard Time (AWST), which is UTC+8. This change was made to align with the rest of the country, which is already on Australian Eastern Standard Time (AEST) UTC+10.
Prior to this change, Western Australia was on Western Australian Standard Time (WAST), which was UTC+8.5. The new time zone is 1 hour ahead of the previous one.
So, if you're in Western Australia, you're now on AWST (UTC+8), and if you're in the eastern states, you're still on AEST (UTC+10).
