frequencies
Point Ormond - being very close to Albert Park Lake - will see aircraft entering/exiting Essendon Zone on 125.1 - not 135.7 - either seeking a clearance or getting permission to close the EN TWR frequency. During my training at MB we were often encouraged to go straight from MB frequencies to EN so as to improve situational awareness of the upcoming Class C ahead.
Not everyone has 2 comms (or uses them) and so the first an aircraft exiting EN might know about parachutes is the drop call.
I still think it's a terrible place for a DZ.
