Line Rental / Network Access

This is an itemised break down of the 'Recurring Charges' appearing in the area labelled 'L'. Recurring charges are Line rental or monthly plan and feature charges. Advanced charging & Pro-rata billing apply to most of the charges appearing in this section.

Why are there 2 of each recurring charge? Is this an error?

No. Recurring charges are billed a month in advance, the first bill you receive after activation or a change to your plan will show two of each item to bring each of these charges one month ahead of your invoice period. You may find a different amount charged against each repeated item Here's why...

The first of each repeated charge is from the date your plan or feature was activated/changed, to the end of this bill's invoice period (indicated on Page 1 by 'A') and will only be a part or a proportion of the normal monthly fee for that item. It is usually a partial fee as it's likely that the start/change to your service occurred only part way through your billing month. (Charging a part of a normal amount is known as pro-rata billing)

The second of each repeated charge is for the full month ahead of this bill, so the fee will be the full monthly rate and now charge in advance. Remember, the amounts displayed in these sections exclude GST.

If you've changed plans/features you may also see a credit for any unused advance charges that appeared on a previous bill.

Will this occur every month?

Unless you make further changes to your service, your next bill with have only 1 item for each 'Recurring Charge' - Return to Page 3.


Community & Local Calls

The total number of local calls & community calls are made during the billing period are listed here.

A 'Community call' is call that would otherwise be charged at National call rates, as the charging zone in which the calling party is located is not adjacent to the charging zone in which the called party is located. However Optus has designated the two areas to have a community interest and therefore charges a reduced 'Community Call' rate between the two areas.

Detailed information about Community Calls is available in the Home Phone Standard Form of Agreement (SFOA) - Return to Page 3.

Fixed Line Phone Call Times & Lengths

Is the time of a call on my bill, local time?

The time of a call shown on your bill, is the local time recorded at the first local exchange or other network facility through which your call passes, in most cases this means the time will be your local time.

However, in some circumstances this may not be the local time at the place where the call is located.

For example: If you live close to or on a state border and a time difference exists between these two states. A call made from your home state may first route via a network facility in the neighbouring state resulting in the time of call reflecting the time in the neighbouring state, rather than that of your home state.

What happens if a call crosses over a designated peak/off peak time or other discount time period?

  • Fixed Line Home Phone

The charging rate of your call is calculated based on the starting time of your call. For example, if a call starts in a peak period and finishes in an off-peak period, the charge will be calculated at the peak period rate.

  • Wireless Home Phone

Generally the time of a wireless home phone call will be determined throughout the call. For example, if a call starts in a peak period and finishes in an off-peak period, the charge will be calculated pro-rata using the peak and off-peak rate.

How do we rate the length of a call?

Depending on your rate plan you may be charged either per second, in 30 second intervals or per minute, in each case we round the charge to the nearest cent.

For example: If your rate plan directs your calls to be expressed as per thirty second interval, then charges for part of thirty seconds will be rounded up to the next thirty second interval and cent.

Detailed information on how we calculate your charges is contained within the Home Phone Standard Form of Agreement (SFOA)
