The barrier draw was today held in confidence by Racing NSW stewards and the results will be kept private until they are beamed onto the Opera House sails.
Betting on The Everest has been suspended as of midday Tuesday, with the revelation the barrier draw has been conducted but will only be made public on Tuesday night via the publicised Opera House projection.
The Sydney Opera House initially rejected the proposal but a state official overruled and allowed a revised 10-minute projection of the ad for October 9.
Here's a look at the protest at the Opera House on Tuesday evening.
Protester Joshua Richardson, 19, said he had no problem with the Opera House being lit up in the "right context" but said this illumination was "horrible".
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.
The NSW government is facing a growing backlash this week after it ordered the Opera House to display a promotion for Racing NSW over the objections of the building's caretakers.
"The Opera House management has approved exemptions under the Heritage Act to make these types of decisions", the spokesman said.
"It is the view of the Heritage Council that the use of the Opera House for the commercial advertising of this event is completely unsatisfactory and is an inappropriate use of this significant heritage place that is valued by many around the world", he said.
"Gave her a big talking to. you're allowed to project on there, that's the biggest billboard in Sydney, mate".
On Friday, Mr Jones had called for Ms Herron's sacking after she resisted The Everest's initial proposal, saying the building was not a "billboard".
'I don't know why people are getting so precious about it.
The apology came hours after The Chaser had taken matters into their own hands, with a stunt that saw them project what was "apparently" Jones' real phone number onto a number of Sydney landmarks including the Opera House.
