From the report:
Unavailability of the runway 16ILS
In September 2007, work commenced on the Melbourne runway 16 ILS to permit the installation of new equipment. That work was part of a navigation aid replacement program that Airservices Australia had announced to the aviation industry in October 2005. A Notice to Airmen (NOTAM) was issued by the Australian NOTAM Office on 4 October 2007 to inform appropriate personnel of the planned unavailability of the runway 16 ILS. The NOTAM advised that the ILS would be unavailable from 0900 local time on 8 October to 1700 on 22 November 2007.
