Does daylight saving change AWST to GMT?
Australian Western Time does not move its clocks at all, so its UTC+8 offset holds every day of the year.
Greenwich Mean Time does not move its clocks at all, so its UTC+0 offset holds every day of the year.
Is AWST ahead of or behind GMT?
AWST is ahead of GMT by 8 hours: when it is 12:00 pm in Australian Western, it is 4:00 am in GMT. Neither Australian Western Time nor Greenwich Mean Time observes daylight saving, so the abbreviations never change and the gap between them is fixed.
Australian Western Time covers Perth and Western Australia, which stopped moving its clocks in 2009. Greenwich Mean Time covers identical to UTC as a clock reading, and a separate thing as a standard. The identifiers behind them are Australia/Perth and Etc/GMT, which is what any calendar or scheduling system should be storing rather than a fixed number of hours.
