Why Is My Bill Higher Than Usual?

Estimated Reading Time: 2 Minutes

If your bill is higher than expected, there are several common reasons why this may have happened. Below are the key factors that could lead to an increased bill amount.

Common Reasons for a Higher Bill

1. Pro-rata Charges

If this is your first bill or you’ve recently added a new service, you may see a charge for the partial service period before your full billing cycle began. This aligns your charges with your regular billing cycle. Subsequent bills will then reflect just the standard monthly plan charge.

 

2. One-Off Charges

Some charges are non-recurring and may appear on your bill only once. These include:

  • Hardware fees (e.g., purchasing a new modem or handset)

  • Activation fees

  • Postage or shipping costs

3. Excess Usage Charges

If you’ve exceeded your plan’s allowances, additional fees may apply for:

  • Extra data usage

  • Calls beyond your included minutes

  • SMS/MMS messages beyond your plan limits

 

4. Administrative Fees

Certain fees may be added depending on your billing activity, including:

  • Late payment fees

  • Dishonor or chargeback fees

  • Payment processing fees for some payment methods

5. ACMA Levy

The Australian Communications and Media Authority (ACMA) requires a $0.65 annual levy per active mobile service. If this has been applied, it will appear as a once-off charge.

 

Other Factors That Can Increase Your Bill

Plan or Service Changes
  • If you upgraded to a higher-tier plan, your new monthly fee may be higher.

  • Adding additional services (e.g., extra data packs or international calling add-ons) may result in increased charges.

Expired Discounts or Offers
  • Some plans include introductory discounts that expire after a set period. If your bill increased, check if a discount has ended.

Billing Errors or Adjustments
  • Occasionally, an adjustment or correction from a previous bill may be reflected in the current invoice. If you believe there is an error, please check your bill details or contact support.
