Thousands of protesters gathered outside the Sydney Opera House to protest The Everest horse race advertisement on Tuesday night.

The 6-minute advertisement promoting the $13 million horse race was set to be projected on the sails of the iconic Sydney landmark at 8pm AEDT but went live shortly before.

Earlier in the day, Racing NSW also brought forward the barrier draw “to circumvent any security risks that may exist”.

An estimated 2,000 people bearing torches surrounded the base of the Opera House on the foreshore of the harbour and attempted to interrupt the display.

Protesters booed and chanted “turn it off” as the barrier draw results were revealed.

While the mass of people was staggering, their lights did not seem to affect the projections.

Here’s a look at the protest at the Opera House on Tuesday evening.

On Tuesday afternoon, Racing NSW suspended betting for The Everest horse race “to avoid any perceived integrity risk”.

The racing regulating body will later advise all wagering operators when they may recommence betting on the race.
