GMT to AWST Time Converter
About this conversion
AWST is Australian Western Standard Time (UTC+8), used in Perth and Western Australia. Western Australia does not use daylight saving, so it is eight hours ahead of GMT all year.
AWST is the only Australian standard time that does not change, so the gap with the UK is eight hours in winter and seven hours in summer.
When the time difference changes
Both sides keep a fixed offset, so the gap does not change in the next two years.
