It depends on how you record a service interruption. Lies, damn lies and statistics. I have consistently said that I probably miss half the number of NOTAMs that I capture.
Some Tower locations have reduced hours when compared to ERSA. Alice Springs, Avalon and Parafield are examples.
Sometimes a service interruption is for a full shift (or close to it), others are to provide the ATC with a break, or for the non 24/7 locations, a start late and/or finish early, which either relates to availability or perhaps a FRMS control or other rostering rule.
Then if you refer to the service disruption referenced in the AFR article.

Technically 3 different sector volumes as defined in DAH but they would never be operated on 3 separate consoles. Two different time periods. Is this 1, 2 or 6 service interruptions? I would count it as 2.
Anyways, 20/12 to 2/1, I counted 38 different time periods.
