Thanks for the informaiton. The finder website is handy. I check the service class for my area and get
Service Class: 10ADA: 2CAS-22-06 for the properties with existing Telstra cable connection (includes mine, this time looks correct) and
Service Class: 10ADA: 2CAS-22-05 for the properties do not have Telstra cable connection.
Only the last number is different and not sure what does it present. Different connection type or just different stage?
