A member of the Myer family has replaced a scion of the Transfield dynasty as chairman of the Australian Chamber Orchestra.

After 24 years at the helm of the renowned string ensemble, Guido Belgiorno-Nettis – the youngest son of Franco, the Italian immigrant who co-founded Transfield in 1956 and transformed it into an engineering giant – retired from the chairmanship at an ACO board meeting at its new Walsh Bay headquarters last Thursday.
