Australian Eastern Time explained

AET stands for Australian Eastern Time. It's the umbrella term for the time zone used across Australia's eastern states and territories.

Here's the thing - AET isn't fixed like other time zones. It automatically switches between Australian Eastern Standard Time (AEST) and Australian Eastern Daylight Time (AEDT) when daylight saving starts and ends.

During winter (April to September), AET runs on AEST, which is UTC+10. During summer (October to March), it shifts to AEDT at UTC+11. Your phone handles this automatically, so you don't need to think about it.

Why we use AET in our documentation

We serve customers right across Australia - from Perth to Hobart, Darwin to Sydney. When we list our support hours and documentation times, we need one consistent reference point that works for everyone.

AET does exactly that. It's simple, it's accurate, and it doesn't need updating twice a year when daylight saving kicks in or out. When we say support is available 8am to 8pm AET, you can work out what that means for your local time zone depending upon what time of year it is.

What this means for your state or territory

Australian Capital Territory, New South Wales (except Broken Hill), Tasmania, and Victoria

Your local time is AET.

When you check our support hours or documentation, just look at your clock.

Queensland

You're on AEST all year round.

During winter, that's the same as AET.
During summer when southern states spring forward to AEDT, you'll be one hour behind the AET times we reference.

South Australia and Northern Territory

You're on Australian Central Time (ACT).

SA is 30 minutes behind AET year-round (you also observe daylight saving).
NT is 30 minutes behind during winter, and 1.5 hours behind during summer (you don't observe daylight saving).

Western Australia

You're on Australian Western Time (AWST).

You're 2 hours behind AET during winter and 3 hours behind during summer (you don't observe daylight saving).

Some of our Plans are eligible to rollover unused data allowance to your next recharge period. Check our Critical Information Summaries to confirm eligibility.

When will my data rollover?

If your current plan is eligible for data rollover and you renew the same plan by recharging within 24 hours of it expiring, your data will rollover (how much will depend on your specific plans rules).

What happens if I change plans?

If you are changing plans, you may be eligible to rollover your data.

Data will rollover when you change plans within 24 hours of your previous plans expiry when the following occurs:

Your new plan is within the same plan group (e.g. Mobile Plan to Mobile Plan), and;
The new plan is of a higher value than your current plan (e.g. $25 Mobile Plan to $35 Mobile Plan).

If you are on a Family Plan, please note that you are not able to change to another Family Plan.

How much data can I rollover?

If your eligible recharge is on a Mobile Plan, Family Plan or 1 Year Super Pack, all you unused data will rollover.

If your eligible recharge is on Data Plan, the amount you can rollover is determined by your Data Plan, if you have more data that your plans rollover allowance the additional data will not rollover and will be forfeited.

How does data rollover work?

If your recharge is eligible and you are able to rollover unused data, your plan will have a data balance linked to your current plans allowanced and a data rollover balance which contains the data you have rolled over.

When using data, your plans allowance is used first and if this has been exhausted you will then consume data from your data rollover balance.

If you have data rollover and your next recharge is not eligible for data rollover, all unused data on your service will be forfeited.

When will my data not rollover?

Your data will not rollover when the following occurs:

Your recharge occurs 24 hours or more after your current plans expiry;
If you move to a different type of plan (e.g. a Mobile Plan to a Super Pack), your data will not rollover, even if the new plan value is higher.
If you move to a lower value plan (e.g. $35 Mobile Plan to $25 Mobile Plan), you data will not rollover, even though you are changing plans within the same plan group.

Some of our Plans are eligible to rollover unused data allowance to your next recharge period. Check our Critical Information Summaries to confirm eligibility.

When will my data rollover?

What happens if I change plans?

If you are changing plans, you may be eligible to rollover your data.

Data will rollover when you change plans within 24 hours of your previous plan's expiry when both of the following conditions are met:

Your new plan is within the same plan group and validity period as your current plan (for example, a 30-day Mobile Plan to another 30-day Mobile Plan); and
Your new plan is of a higher value than your current plan.

Please note: To change to a different Family Plan, your current Family Plan must first be removed before the new one is applied. As a result, rollover data can't be carried across.

How much data can I rollover?

If your eligible recharge is on a Mobile Plan, Family Plan or 1 Year Super Pack, all you unused data will rollover.

How does data rollover work?

If your recharge is eligible and you are able to rollover unused data, your plan will have a data balance linked to your current plans allowance and a data rollover balance which contains the data you have rolled over.

If you have data rollover and your next recharge is not eligible for data rollover, all unused data on your service will be forfeited.

When will my data not rollover?

Your data will not rollover when the following occurs:

Your recharge occurs 24 hours or more after your current plans expiry;
