It comes at a time when there has already been significant backlash after radio host Alan Jones stepped in to implore NSW premier Gladys Berejiklian to allow The Everest to beam images on the Opera House's iconic sails.
It today announced that all betting on the 2018 The TAB Everest will be suspended from 12pm AEDT, until the final barriers have been publicly displayed on the Opera House this evening.
"The draw was done within our normal protocols on Tuesday morning and only myself and my deputy Philip Dingwall know the results", Racing NSW chief steward Marc Van Gestel said.
The original plan was to conduct a live barrier draw and project the result onto the Opera House sails.
The race is billed as the world's richest and has $13million in prize money up for grabs as well as a performance by former One Direction member Liam Payne.
The Racing NSW promo is set to appear on the side of the Sydney Opera House on Tuesday evening.
Tropical Storm Michael Nearing Hurricane Strength
In Florida, state offices, schools and universities were set to close Tuesday through the end of the week in panhandle counties. Heavy rains at the weekend caused 13 deaths in Central America after Michael formed off the coast of northern Honduras.
"In an official statement, Racing NSW said: "[We have] made the decision to conduct the draw prior to the event to circumvent any security risks that may exist".
Political manipulator Jones, whose superpower is to be able to wrap gutless Liberal Party politicians around his little orifice, is behind the verbal bullying of Opera House CEO Louise Herron.
Jones had called for Ms Herron to be sacked during a testy confrontation on Friday after she ruled out allowing words or branding highlighting The Everest race to be projected onto the Opera House because "it's not a billboard".
In a letter to the premier on Tuesday, the NSW Heritage Council said it was extremely disappointed with the government's decision and described the projection as "inappropriate".
Mr Greenwich said he would move a motion in parliament to amend the Sydney Opera House Trust Act to "stop the culture of a minister picking up the phone on behalf of his mates in the racing industry and telling the Opera House what to do".
"I used some words in these programs about the Everest, and the Opera House, and Louise, which in hindsight I now most regret hearing, having heard the impact they've clearly had on some people", he told his 2GB listeners this morning.
