Many of us read "On the Beach" in HS in the 60's. (My son read it in HS in the 90s). Some may remember the wonderful miniseries of "A Town Like Alice" with Bryan Brown and Helen Morse.
Most people don't realize he wrote 22 other novels. Everyone a jewel.
He was also a famous aviation engineer, entrepreneur and designer of weird weapons in WWII.
My two favorites are "A Town Like Alice" and "Trustee from the Toolroom" I read them over and over and over.
