The Sydney Theatre Company is being urged to engage with the Jewish community or suffer further losses as an insider confirmed for the first time that at least $1.5 million has already been lost from a boycott by subscribers and patrons following a pro-Palestinian protest by three of its actors.

An insider with direct knowledge of STC’s finances confirmed $1.5 million as an estimate of losses from refunded ticket purchases, and the cancellation of previously promised donations, related to the wearing of Palestinian scarves by three actors at the curtain call of an STC play on November 25.
