Australia Local time used in
Perth is exactly eight hours ahead of the standard
Greenwich Mean Time. Other cities and states across
Australia are also advanced (but differently) to
If you want to know by how much time, you

Since standard time was adopted by the country in
1890s, all states, territories and colonies of
Australia have implemented their respective standard
times. The nation-continent has three major time
zones in reference to the GMT.
Standard Time or AEST is 10 hours ahead of GMT.

Tasmania, Australian Capital Territory, and
Australian Central Standard
Time is 9.5 hours ahead of GMT. It is observed
across the states of Northern Territory and South
Australia. Lastly, Australian Western Standard Time,
which is solely observed in Western Australia, is
eight hours ahead of Greenwich Time.
Aside from the three major time zones, external
territories are also using their own time zones.
This is because such islands are geographically far
from the main continent, making it obviously
impractical to apply the three major Australia time
zones to them.
The territories of Norfolk
Island (11.5 hours ahead of GMT); Australia Antarctic
Territories of Casey (8 hours ahead of GMT), Davis (7 hours
ahead of GMT), and Mawson (6 hours ahead of GMT); Christmas
Island (7 hours ahead of GMT); Heard and McDonald Islands (5
hours ahead of GMT); and Cocos Islands (6.5 hours ahead of
GMT) all have varied time zones.
There are also specific Australian states that are observing
daylight saving time. These are New South Wales, Tasmania,
Australian Capital Territory, South Australia, and Victoria.
The Northern Territory and Queensland are not implementing
and using daylight saving time, though the states had tried
doing so in the past. In areas where daylight saving time
prevails, time is usually further advanced by at least an
hour to maximize daylight use and eventually generate cost
savings and lower energy consumption.
There are several known anomalies and controversies
involving Australia time difference. For one, there are
island resorts in the northern portion of Queensland that
are unofficially implementing daylight saving time on their
events and activities. Broken Hill, a town in far-western
portion of NSW is following time used in South Australia.
Some towns in Western Australia prefer to follow Central
Western Standard Time, a modification of central and western
standard times. That is because such towns are located at
the border of Western Australia. South Australian towns of
Mundrabilla, Eucla, Madura, and Border Village are also
shifting away from state town zone and instead are using
Central Western time.
