Time Zone in Australia

Australia started its time standardization in 1892, at a time when surveyors coming from Australia colonies convened in Melbourne, Victoria for the important Inter-colonial Conference of Surveyors.


Delegates of the convention approved the 1884 recommendation by the International Meridian Conference for the country to implement GMT or Greenwich Mean Timer, which became the basis for local standard time.


The move was also in line with usual time practice globally.


The convention devised its own time zone system with offsets in one-hour multiples from standard GMT.



These three major time zones were later known as the modern Western, Central, and Eastern Australian standard time, respectively.

Australia’s numerous external territories are also following their respective and own time zones.
Australia time zone has rules. State legislations set standard and daylight savings times.


If there is something to be done in specific time, the person setting the job task is required to complete the requirement by the specified time. It is also a standard practice in Australia that contracts should specify required time of completion.

By February 1895, the legislation for a national standard time was enacted and took effect.


From then on, time in Western Australia spearheaded GMT by about 8 hours. South Australia led GMT by 9 hours, while New South Wales, Tasmania, Victoria, and Queensland led 10 hours.

The national government is also recognizing state governments’ power to implement and adopt standard time. This covers ideal working hours of government employees, local elections, and implementation of scheduled public holidays.

Needless to say, Australia time zones vary depending on the state geography. Australia is a nation-continent. Thus, its total land area is so huge that the country should be practically divided into different time zones to benefit all industries, residents, and workers. However, just like other good government practices, decisions about time management and manipulation are solely left to the state governments.

The Commonwealth government has given State and Territory governments the responsibility and authority to implement standard time in relation to the standard Coordinated Universal Time or UTC. The International Bureau of Weights and Measures provide basis for the application of standard time in Australia under the Commonwealth government’s National Measurement Act of 1960, specifically section 8AA. The National Standards Commission also has a say in time standardization. The commission is mainly responsible in giving the national government advice on technicalities involving the national measurement system.

If you are taking a vacation in Australia, or exploring the country through travels, you should always consult maps and determine what time zone is used in the area where you currently are. Of curse, different time zones mean that there is not one time in the country. Respective and appropriate designations of time zones are pre-determined and conducted formally.
