Why Perth Gets 2 Hours More Daylight Than Sydney in Summer
Australia spans three time zones but uses... different rules. Here's why sunrise and sunset times vary so wildly across the country.
Ever noticed that Perth's summer evenings seem to last forever while Sydney is dark by 8pm?
You're not imagining it. Australia's daylight situation is genuinely weird.
The Numbers Don't Lie
Summer Solstice (December 21st):
| City | Sunrise | Sunset | Daylight |
|---|---|---|---|
| Perth | 5:05 AM | 7:24 PM | 14h 19m |
| Adelaide | 5:58 AM | 8:22 PM | 14h 24m |
| Melbourne | 5:55 AM | 8:44 PM | 14h 49m |
| Sydney | 5:39 AM | 8:05 PM | 14h 26m |
| Brisbane | 4:49 AM | 6:44 PM | 13h 55m |
| Darwin | 6:04 AM | 7:07 PM | 13h 3m |
Wait—Brisbane gets the least daylight of any major southern city? And Perth's sunset at 7:24 PM seems early until you realise...
The Time Zone Problem
Australia's time zones are political, not logical.
The zones:
- AWST (Perth): UTC+8
- ACST (Adelaide, Darwin): UTC+9:30 (yes, half an hour)
- AEST (Sydney, Melbourne, Brisbane): UTC+10
Daylight Saving Time:
- WA (Perth): NO DST
- QLD (Brisbane): NO DST
- NT (Darwin): NO DST
- SA, VIC, NSW, TAS, ACT: YES DST (+1 hour)
This creates chaos.
The Real Daylight Hours
When you adjust for DST in summer, the picture changes:
Actual sunset times on December 21st:
- Perth: 7:24 PM (no DST)
- Brisbane: 6:44 PM (no DST)
- Sydney: 8:05 PM (with DST, would be 7:05 PM without)
- Melbourne: 8:44 PM (with DST, would be 7:44 PM without)
- Adelaide: 8:22 PM (with DST, would be 7:22 PM without)
So Perth's "early" sunset is actually later in real solar time than Brisbane's.

Queensland held referendums on DST in 1992. It failed 54.5% to 45.5%.
The arguments against:
- "Curtains will fade faster" (real argument, surprisingly common)
- Farmers already wake before dawn anyway
- Northern QLD is closer to the equator (less variation)
- Confusion with PNG, which doesn't use DST
Brisbane business groups have pushed for DST repeatedly. The answer remains no.
Perth's Glorious Evenings
Perth sits at the western edge of its time zone, which means:
- Late sunrises (5:05 AM is late for Australian summer)
- Late sunsets
- More useful evening daylight
In practical terms: after work BBQs in Perth have more daylight than anywhere else on the mainland.
The 4:49 AM Problem
Brisbane's summer sunrise at 4:49 AM is considered "too early" by locals. Without DST:
- It's light at 4:30 AM
- People wake up earlier than they want
- Evening is dark by 7 PM
With DST, sunrise would be 5:49 AM and sunset 7:44 PM—more useful for most people.
How Latitude Affects Daylight
The further south you go, the more extreme the daylight variation:
Summer daylight hours:
| City | Latitude | Daylight |
|---|---|---|
| Darwin | 12°S | 13h 3m |
| Brisbane | 27°S | 13h 55m |
| Perth | 32°S | 14h 19m |
| Sydney | 34°S | 14h 26m |
| Melbourne | 38°S | 14h 49m |
| Hobart | 43°S | 15h 23m |
Hobart gets over two hours more daylight than Darwin in summer.
Flip that in winter:
- Hobart: 9h 17m of daylight
- Darwin: 11h 22m of daylight
Planning Around Daylight
If you want long summer evenings:
- Melbourne (8:44 PM sunset with DST)
- Adelaide (8:22 PM)
- Sydney (8:05 PM)
- Perth (7:24 PM—but no DST, so relatively late)
- Brisbane (6:44 PM—no DST, earliest of major cities)
If you want gentle winter mornings:
- Darwin (consistent ~6 AM sunrise year-round)
- Brisbane (relatively stable)
- Perth (moderate variation)

The Weirdest Australian Time Fact
When it's 12:00 PM in Sydney (summer), it's:
- 11:30 AM in Adelaide (30-minute difference)
- 11:00 AM in Brisbane (same zone, no DST)
- 9:00 AM in Perth
And there are tiny pockets of Australia that use their own time:
- Eucla, WA: UTC+8:45 (unofficial, but locals use it)
- Broken Hill, NSW: Uses SA time despite being in NSW
The Bottom Line
Australia's daylight is weird because:
- Three time zones that don't match solar noon
- Inconsistent DST rules
- A very wide country
Perth residents genuinely get the best evening light. Queensland could have it too. They just... don't want it.
