Joe Byrne commenced school at the Catholic school at Woolshed in 1862. He was a good student, normally among the top students in his class and developed a reputation as a "flash writer". He also became very good friends with fellow student Aaron Sherritt. However, Byrne's father Patrick developed heart disease and Byrne's school results suffered. He finished school in 1869 with a fifth-grade education while his father died in the same year from heart disease. Joe Byrne also learnt how to speak Cantonese from nearby Chinese gold miners and learned how to smoke opium.
