Alternate due to facilities
AIP ENR 1.1
For night VFR operations, alternate requirements relate to airport lighting and navaids. Where these facilities are subject to operational changes (for example, due to maintenance, malfunction, upgrade or decommissioning) and these changes have been reported to the Airservices Australia NOTAM office, you will find details about the change in the NOTAMs. During your pre-flight planning where the use of air navigation facilities is required for your flight, it is essential that you check NOTAMs so you meet operational requirements. The details of these requirements are given in the night VFR section on page 3.132.
