Racing NSW officials have named six potential emergencies for slot-holders for The Everest this Saturday, while they have also suspended betting on Tuesday afternoon after the barrier draw was conducted.
Comedians have ridiculed the NSW government's plan to promote a horse race on the sails of the Sydney Opera House by projecting the words "Advertise here".
The decision to cancel the live barrier draw came hours after broadcaster Alan Jones publicly apologised for his on-air treatment of the Opera House chief executive.
Controversy surrounding the barrier draw has given the race and Sydney's iconic Opera House global publicity.
"I don't believe my words or actions qualify as those of a bully or a misogynist but there are clearly many people who do", Jones said on 2GB. "This is much bigger than one Prime Minister, or one party, or even one government", he said.
On Monday National Trust NSW conservation director Graham Quint suggested the move to project advertising onto the Opera House could be illegal, given its commercial nature.
The change.org petition titled Defend our opera house: support Louise Herron, had passed 265,000 signatures by The Mandarin's Tuesday midday publication time.
Protesters pointed their torches and flashlights at the sails, where horse numbers, colours and a logo for The Everest would be projected, in an attempt to wash it out.
"Unless for a specific artistic goal in relation to Sydney Opera House, text or slogans will not be permitted", the policy reads.
In another letter sent to Greens MP David Shoebridge, Mr Davies said he was unable to issue a Stop Work Order because the planned projections by Racing NSW did not meet the legal definition of "harm" as there was no physical damage being done to the site.
"The Opera House management has approved exemptions under the Heritage Act to make these types of decisions", the spokesman said. The guidelines have always been stretched in the part and the commercialisation of the Opera House has always been there.
