Apart from that 30,000 feet was intended. Whether you are a pelican (not
likely), pilot or passenger at 30,000 feet near Sydney, I'm sure you cannot
see central Australia nor clouds over it. I'm no frequent flyer but I love
looking out the window when I do. Assuming a fairly flat landscape I don't
know but I'd surprised if from a normal interstate plane you could see the
land surface much more than 100 km away.
The question is that many birds seem to be able to time their arrivals at
rare and irregular inland waters from places far away. Presumably they
detect something as a sign of these conditions.

I wrote a message yesterday to the pilot of a QANTAS plane that I was on,
telling him that it had been reported that pelicans can fly as high as
300,000 feet, and asking him. If you were at a height of 30,000 feet near
Sydney, would you be able to see rain falling in central Australia. He
reputed the idea that pelicans fly that high. So, where did the information
come from, about the height that pelicans can fly? and is it a myth?
