Australian Western Time does not move its clocks at all, so its UTC+8 offset holds every day of the year.
Is BRT ahead of or behind AWST?
BRT is behind AWST by 11 hours: when it is 12:00 pm in Brasilia, it is 11:00 pm in Australian Western. Neither Brasilia Time nor Australian Western Time observes daylight saving, so the abbreviations never change and the gap between them is fixed.
Brasilia Time covers Sao Paulo and Rio de Janeiro, fixed since Brazil dropped summer time in 2019. Australian Western Time covers Perth and Western Australia, which stopped moving its clocks in 2009. The identifiers behind them are America/Sao_Paulo and Australia/Perth, which is what any calendar or scheduling system should be storing rather than a fixed number of hours.
