Best meeting time between Australia and UK
Australia and the UK are roughly nine to eleven hours apart on the East Coast, and seven to eight hours apart on the West Coast. There is no overlap of traditional business hours, so every Australia–UK meeting requires one side to take an early or late slot. The good news: the same two windows work almost every time of year.
The time zones in play
The UK swings between GMT (UTC+0, winter) and BST (UTC+1, summer). Australia is more complicated:
- AEST/AEDT — UTC+10 / UTC+11. Sydney, Melbourne, Hobart, Canberra. Brisbane stays on AEST.
- ACST/ACDT — UTC+9:30 / UTC+10:30. Adelaide. Darwin stays on ACST.
- AWST — UTC+8. Perth. No daylight saving.
The two practical windows
Across both seasons, two slots dominate AU-UK calendars:
- UK morning ↔ Australia evening. Sydney 18:00–20:00 equals UK 08:00–10:00 in winter. Australia takes a post-work slot from home, the UK takes a fresh morning. Best for low-frequency calls.
- UK late afternoon ↔ Australia early morning. Sydney 07:00–08:00 equals UK 21:00–22:00 in winter. Better for short stand-ups where the UK side can take an after-dinner call.
UK morning vs. Sydney evening: the favourite
| UK (GMT) | Sydney (AEDT) | Verdict |
|---|---|---|
| 07:00 | 18:00 | Edge of UK day, dinner hour Sydney |
| 08:00 | 19:00 | Best mutual window |
| 09:00 | 20:00 | Workable both sides |
| 10:00 | 21:00 | Late for Sydney |
| 12:00 | 23:00 | Avoid |
Including Perth and Brisbane
Perth (AWST) is two hours behind Sydney in the Australian winter and three hours behind in summer. That actually makes Perth easier to schedule with the UK: Perth 14:00 AWST is UK 06:00 GMT — very early UK, but workable for short calls. Brisbane stays on AEST year-round, so during Australian summer it sits an hour behind Sydney; the same UK slots apply, just shifted by one hour.
The DST overlap and the "narrow gap" weeks
For a few weeks each year, the gap between Sydney and London is exactly 9 hours rather than the usual 10 or 11. This happens when Sydney has dropped AEDT (in early April) but the UK has not yet entered BST, and again briefly in October. During these windows, recurring meetings pinned to UK time will appear an hour earlier or later than expected on the Sydney calendar. Calendar tools that respect time zones handle this automatically; emails and screenshots do not.
Operating cadence that works
- Daily 30-minute sync at UK 08:00 / Sydney 19:00 (winter), or UK 09:00 / Sydney 19:00 (summer). Keeps both sides on the clock once.
- Weekly leadership at UK 09:00 — the UK takes a fresh morning and the Australian leadership takes a contained evening slot.
- Quarterly all-hands on a Thursday UK / Friday Sydney to minimise the carry-over into the weekend.
FAQ
What is the best AU-UK meeting time?
UK 08:00–09:00 (GMT) which is Sydney 19:00–20:00 (AEDT) in the Australian summer.
Can we meet during business hours on both sides?
No. The offset is too large. One side will always need to take an early or late slot.
Does Perth have an easier overlap with the UK than Sydney?
Slightly. Perth's AWST is two to three hours behind Sydney, so 14:00 Perth equals 06:00 UK GMT — usable for short calls.
