He was educated at Prince Alfred College and Roseworthy Agricultural College before spending three years following "pastoral and financial pursuits". He then studied law at the University of Adelaide, serving his articles with George Ash and graduating in March 1897, aged 24.
He was admitted to the Bar later in 1897. He joined with Patrick McMahon Glynn, KC. in partnership in 1898; they were joined in October 1908 by George McEwin and subsequently by (later Sir) Mellis Napier.
In 1912 he stood for parliament and was elected member of the South Australian House of Assembly for Torrens (1912-1915), and subsequently member for Murray. It was around June of this year that he became universally referred to as "Angas Parsons". He was briefly Attorney-General of South Australia and minister of education in 1915. Parsons was appointed K.C. in 1916, a judge of the Supreme Court in 1921, senior puisne judge in 1927, and acting chief justice in 1935. On occasions Parsons acted as deputy governor and, after his father's death, in 1904 he became consul for Japan.
