Australia Time Zones Guide

Eastern, Central, Western zones; southern-hemisphere DST and states that opt out.

Australia uses three main standard zones with **state-level DST** rules — very different from a single-zone country like China. Southern-hemisphere DST runs roughly October–April, opposite the northern season.

Main IANA zones

  • Australia/Sydney, Australia/Melbourne — Eastern (AEST/AEDT)
  • Australia/Brisbane — Eastern, **no DST** (Queensland)
  • Australia/Adelaide — Central (ACST/ACDT, UTC+9:30/+10:30)
  • Australia/Perth — Western (AWST, UTC+8, no DST)
  • Australia/Darwin — Northern Territory, no DST

DST notes

NSW, Victoria, SA, and Tasmania usually start DST on the first Sunday in October and end on the first Sunday in April. Queensland, WA, and most of NT do not shift. Sydney vs Brisbane differs by 1 hour during DST. See DST Guide and Half-Hour and Quarter-Hour Time Zones.

International scheduling

Sydney AEDT vs Beijing may be only 3 hours apart in summer. Always use the Convert with a date. Never assume one "Australia time" in International Meetings.
