Time difference between Bangkok and Sydney

Sydney is 3 hours ahead of Bangkok

Bangkok, Thailand is UTC+7 · Sydney, Australia is UTC+10 — on standard time

Every converter gives one number for this pair. That number is right for most of the year and wrong for part of it, because Bangkok does not change its clocks and Sydney goes forward on the first Sunday in October and back on the first Sunday in April.
