As I said previously at typical helicopter VFR altitudes there is no coverage over about 90% of Aus.
That's why it's prudent to keep the second radio on 121.5. Normally will get an instant answer in an emergency from a high flying airline .
The CASA/AMSA recommendation of the area frequency will quite often result in no communication.
It's called airmanship - taught to me by Jim Hazelton.
And what's happened to Adelaide? No risk of a collision there? And Darwin?
