Born Elizabeth Olive Wood near Nuku'alofa, Tonga, she was often known as Bess or Pesi Wood. She was a daughter of Reverend Dr A.

She had five brothers and sisters, including Janet Secomb, Monica Maughan and Rev. Dr H. D'Arcy Wood.
Returning to Australia in 1937, Elizabeth was educated Methodist Ladies' College in Melbourne where, in her final year, she topped the state in Greek and Roman History.
At Melbourne University, she majored in English and History, gaining a BA in 1953, and would later undertake her PhD there.

She was also appointed an archivist at Churchill College, Cambridge University, to sort and catalogue the papers of British novelist E. M. Forster after his death in 1970.
She completed a PhD in Tongan history in 1982 at the University of Melbourne and remained a Senior Fellow there at the time of her death. She published her biography of Queen Sālote of Tonga in 1999.
