The draw for the race, being held at Royal Randwick this Saturday, was held in confidence by Racing NSW stewards and kept under wraps until the results were revealed as part of the light show.
A protest is being planned for when the projection takes place, at 8pm on Tuesday night. NSW Premier Gladys Berejiklian later overruled Herron and gave Racing NSW most of what was being asked.
The activist group has criticised Jones for attacking Herron, calling her a "tyrant" and questioning her credentials after she said she wouldn't allow the Opera House to carry advertising for The Everest Cup horse race on its sails.
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.
Earlier in the day, Racing NSW also brought forward the barrier draw "to circumvent any security risks that may exist".
This afternoon the Heritage Council of New South Wales delivered a damning letter directly to the Premier expressing its "extreme disappointment" with her decision to allow the advertising to go ahead.
Meanwhile, Sydney radio broadcaster Jones today apologised for his on-air treatment of the Opera House CEO Louise Herron, an incendiary interview that drew accusations of bullying.
"Our house is a precious gift to the world", Mr Hall said.
At 7.40pm when the famous sails were first lit up, people lining the building's forecourt also began to shine beams of light from torches onto the images in the hopes of obscuring the message.
State and federal politicians have weighed in on the stoush, including Prime Minister Scott Morrison, who believed the promotion of the event was a "no-brainer".
Alan Jones' mobile is probably running hot this morning after those naughty wags at The Chaser projected his phone number onto the sails of the Sydney Opera House alongside the caption, "Advertise here".
