AEDT is 5 hours 30 minutes ahead of IST at the moment. To convert IST to AEST, add 5 hours 30 minutes to the IST time: 9:00 AM IST = 2:30 PM AEDT.

IST (India Time) is used in India and Sri Lanka (UTC+5:30, no daylight saving time). AEST (Australian Eastern Time) is used in New South Wales, Victoria, Tasmania, ACT; Queensland (Brisbane) all year.

IST here means India Standard Time, not Irish or Israel Standard Time. Queensland stays on AEST all year. AEST (Australian Eastern Standard Time) is not in force right now: New South Wales is currently on AEDT. This page uses whichever name applies on the date you pick, so the numbers below say AEDT.
