An instructor at Moorabbin told me a story a few years ago about a bunch of new CPL holders who decided that they would do a trip to Broome (or somewhere remote) after they passed their CPL flight tests.
On the day of departure, the instructor asked them about their paper maps etc, answer was we aren't taking any as we have iPads. Obviously quite legal in this day and age, however to do such a trip with their limited experience without any back up paper maps would have been dangerous and stupid. I think a few $$ may have been spent at the pilot's shop on maps before they left....
