Sir Philip Oakley Fysh was an English-born Australian politician. He arrived in Tasmania in 1859 and became a leading merchant in Hobart. He served two terms as premier of Tasmania and became a leader of the colony's federation movement. He subsequently won election to the new federal House of Representatives (1901–1910) and was invited to represent Tasmania in the first federal ministry, serving as minister without portfolio (1901–1903) and Postmaster-General (1903–1904).

Hugh Mahon was an Australian politician. He was a member of the Australian Labor Party (ALP) and held ministerial office in the party's earliest governments. He served terms as Postmaster-General (1904), Minister for Home Affairs (1908–1909), and Minister for External Affairs (1914–1916). However, Mahon is chiefly known as the only person to be expelled from the Parliament of Australia, for making "seditious and disloyal utterances" about the British Empire. He failed to win his seat back at the by-election.
