It would have more than likely been a neighbour nearby who decided to connect a new phone line to their premises (Two lines) or wanted ADSL. Telstra would have identified a free Pair in the street with no service on it which it would have then allocated accordingly.

Telstra's records in Linux online would've then been updated to reflect no previous service for your Current/New Service to connect on.. Hence requiring Telstra to Haul new cable to the street etc.
