Joseph Wyatt was one of six lessees who took over Sydney's Theatre Royal lease from Barnett Levey in 1835. He later purchased the lease outright from Levey's wife, together with 'all her theatrical property, including the "good will," etc.' (Sydney Monitor, 26 March 1838). Wyatt then opened his own Sydney theatre - the Victoria Theatre. He imported actors from England, but they were not happily received by local Sydney actors (Wyatt's actions may have spurred the opening of Joseph Simmons's City Theatre.)
Wyatt sold the Victoria Theatre in 1854 and opened the Prince of Wales Theatre the following year. He died in 1860 and is buried at St Stephen's, Newtown.
