Original proprietor Thomas Molloy leased the theatre to others, including Ben and John Fuller, and local producer Anita Fitzgerald. Another lessee of the theatre, J.C. Williamson Ltd, is said to have made His Majesty's Theatre the Perth home of musical theatre. The theatre was renovated in 1912 at a cost of £9,000, and again in 1948 at a cost of £11,000. The latter renovation included new backstage electrical fittings and may also have been the time the verandah balconies were removed from the street frontage of the theatre. In 1952, the theatre was leased by the Edgley family and used for "Russian spectaculars". The theatre was redecorated for Edgley and Dawe in 1960, this time at a cost of £7,000. Edgley went on to purchase His Majesty's in 1969. After the Perth Entertainment Centre was completed in 1974, the Edgley productions shifted there, and the newly completed Perth Concert Hall was also favoured as a performance venue due to outdated equipment and general disrepair at His Majesty's. The theatre was sold in 1976 to Sir Norman Rydge.
