Obtaining a position in the office of Grice Sumner and Company he afterwards went into business at Williamstown, and began his public career as a member of the local municipal council.

After his return he suggested the advisability of the colony having a representative in London, and in 1868 the office of agent-general was created, and Verdon was appointed to the position for a period of four years.

On his giving up the agent-generalship he accepted the position of colonial inspector and general manager of the English Scottish and Australian Chartered Bank, Melbourne.
