Sydney is 2-3 hours ahead of Singapore depending on daylight saving time. Singapore uses Singapore Standard Time (SGT, UTC+8) while Sydney uses Australian Eastern Time (AEST/AEDT, UTC+10/+11). When it's 12:00 PM in Singapore, it's 2:00 PM in Sydney (or 3:00 PM during Sydney's daylight saving time).
Singapore does not observe daylight saving time, but Sydney does (October to April). This means the time difference varies between 2 and 3 hours throughout the year.
Best calling time: 7:00 AM - 4:00 PM Singapore time. This corresponds to 9:00 AM - 6:00 PM in Sydney (during standard time), covering Australian business hours.
Singapore and Sydney are both major Asia-Pacific financial centers. Many Australian companies have their Asian headquarters in Singapore, while many Singaporean firms have expanded to Australia. The modest time difference makes same-day business communication convenient.
