Sydney is 5.5 hours ahead of Mumbai during Australian winter (AEST), and 6.5 hours ahead during Australian summer (AEDT). When it's 9:00 AM in Mumbai, it's 2:30 PM (winter) or 3:30 PM (summer) in Sydney.
Mumbai operates on India Standard Time (IST, UTC+5:30) year-round, while Sydney switches between AEST (UTC+10) and AEDT (UTC+11). The difference varies because India does not observe DST.
Early morning Mumbai works best! 7:00 AM - 12:00 PM Mumbai corresponds to 12:30 PM - 5:30 PM Sydney (winter). This gives good overlap for business calls.
Mumbai and Sydney share growing business ties, particularly in IT services, education, and finance. A large Indian diaspora lives in Sydney. Direct flights connect the cities, with Qantas and Air India operating the route.
