Telstra voice mail number
The Telstra voicemail number in Australia is:
1300 555 000
This is the standard number for accessing your Telstra voicemail from a landline or mobile phone. When you call this number, you'll be prompted to enter your voicemail password and then you can listen to your messages, delete them, or record a new message.
Note that if you're calling from a mobile phone, you may need to use the "123" prefix before the voicemail number, like this:
123 1300 555 000
This will help your mobile phone recognize the number as a local call.
