Time difference between Australia and Nigeria
7 hours to 9 hours, depending on the city
Why there is no single answer
Australia spans 2 different offsets in this data — Brisbane, Sydney and Melbourne at UTC+10, Perth at UTC+8. One number cannot cover 2 offsets, so any single figure for "Australia to Nigeria" is a choice of city — declared or not. That is why two sources can both be right and still disagree, and why the useful answer is the table rather than the number.
Every combination
| From | To | Usual difference | Changes in the year |
|---|---|---|---|
| Brisbane | Lagos | 9 hours behind | no |
| Sydney | Lagos | 9 hours behind | yes — also 10 hours |
| Melbourne | Lagos | 9 hours behind | yes — also 10 hours |
| Perth | Lagos | 7 hours behind | no |
When the gap moves
2 of these 4 combinations change by an hour at some point in the year. Brisbane, Perth and Lagos do not change their clocks; Sydney and Melbourne go forward on the first Sunday in October and back on the first Sunday in April. Where the two sides change on different weekends, there is a stretch of days when the difference is what neither party expects.
Frequently asked questions
What is the time difference between Australia and Nigeria?
There is no single figure. Australia spans 4 of the offsets in this data, so the difference runs from 7 hours (Perth to Lagos) to 9 hours (Brisbane to Lagos). Any converter giving one number for this pair has quietly picked a city.
How many hours ahead is Nigeria of Australia?
It depends which part of Australia you mean. The table on this page gives every combination; the extremes are 7 hours and 9 hours.
Does the difference between Australia and Nigeria change during the year?
Yes. 2 of the 4 city combinations here shift by an hour at some point, because the two sides change their clocks on different weekends or one of them does not change at all.
About these places
Brisbane. Brisbane is UTC+10 and does not change its clocks, while Sydney and Melbourne — the same offset in winter — go an hour ahead in October. For half the year Queensland is an hour behind its southern neighbours, which is a standing annoyance for anyone scheduling across the east coast.
Sydney. Sydney is UTC+10 in winter and UTC+11 from October to April. Its summer is the northern hemisphere's winter, so the gap to Europe and North America swings by two hours over the year rather than staying put.
Melbourne. Melbourne keeps the same clock as Sydney, UTC+10 in winter and UTC+11 in summer, and changes on the same dates. The pair are the reason "Australian Eastern Time" needs the Standard or Daylight qualifier to mean anything between October and April.
Perth. Perth is UTC+8, the same as Singapore and Beijing, and is the only Australian capital that does not change its clocks. Western Australia has rejected daylight saving in four referendums, most recently in 2009.
Lagos. Nigeria is UTC+1 with no daylight saving. It matches Central European Time in winter and falls an hour behind in summer, so a standing Lagos–Berlin meeting moves twice a year entirely at the European end.
The same pair from the other end
This page reads the difference as Nigeria against Australia. Nigeria to Australia states the same gap the other way round, which is the one to send someone if they are the one doing the travelling.
