Telco complaints-handling performance

Large and medium-sized telcos with 30,000 or more services send us data about the complaints they receive. We collect this data under the Telecommunications (Consumer Complaints) Record-Keeping Rules 2018.

The data includes:

• the number of complaints received for each type of service
• the time taken to resolve complaints
• details of certain complaint types
• the NBN access technology the customer is using.

The data helps us to identify areas of telcos’ complaints-handling performance that we need to look at more closely.

It also provides transparency to industry, consumers, and government.

• Complaint rates: Average complaints to telcos per 10,000 services fell from 40 to 39.
• Resolution times: The weighted average days to resolve complaints fell from 5.3 to 4.7.
• TIO complaints vs. provider complaints: Rates of complaints being escalated to the Telecommunications Industry Ombudsman (TIO) decreased from 7.2% to 6.6%.

Notes:

• Tables show telcos with 30,000 or more services except where indicated.
• Complaints per 10,000 services is calculated by dividing the number of complaints reported by the corresponding number of services for a telco and multiplying by 10,000.
• Some telcos only provide one type of service, while others operate across multiple service categories.
• Some telcos report separately for different brands, while others, like Telstra with Belong, and Optus with Coles Mobile, report collectively.
• Complaints exclude complaints escalated to the TIO and outage complaints unless specified otherwise.

This ranking shows how many complaints a telco received for every 10,000 services they supplied during the quarter.

A higher number means a larger proportion of the telco’s customers made a complaint.

Complaints per 10,000 services: All services

This ranking shows the average number of days it took each telco to resolve complaints during the quarter. 

A higher number means the telco took longer to resolve complaints.

Average days to resolve a complaint

Complaints can be made to the TIO by a customer to receive further support in resolving a complaint with their telco.

This ranking shows the ratio of complaints made to the TIO vs. complaints made directly to the provider by the telco's customers. Higher percentage means a larger proportion of customers seeking external dispute resolution from the ombudsman for that telco.
