Not sure if there is a connection, but I am trying to find information on my (ex) brother in law, Geoffrey Alan Read who's family all came from South Australia. I'm 50/50% that his brothers name was Frank, maybe a son of your Frank, or even a relative???
I haven't been able to find out anything at all. All I have is that he was married and lived in Sydney's western suburbs and had 5 children, 3 girls and 2 boys. He would be in his late 60's to early 70's now, if still living.
