"I posted one that I should not have and I described."
Tyson Koh, Sydney Open spokesman, says people who take offensive signs of the rally are "part of the problem".
The government of Berejkilian "has given people more than enough reasons to be angry. Those issues should be addressed but assaulting its sex or appearance is not a way of tackling it", he says.

Do not Kill Live Music, we do not They have control over a single expression of anger towards the NSW government. In a big protest there are some [who] push acceptable expression boundaries.

Despite the allegations, the scheme would not affect low risk holidays, "the government has failed to provide clarity and certainty around its risk categories," the society said in a statement.
Among other issues, the rally called for the government to form a round music regulation board to review all regulation affecting live music, developing a transparent industrial standard for policing services and salary medical services, and work with the industry to develop the achievable, effective and robust holiday safety protocols.
Nathaniel Holmes, an Entertainment Architect, whose clients include the Laneway Festival, Splendor in the Grass, Mountain Sounds and FOMO, said the non-fee licenses were a zero game.
"It would be exactly the same because at this moment these great costs do not face these holidays," Holmes said on Thursday.
Justin Smith and Cody Hunt, who attended the rally, said that the issue of live music regulations would affect the way he voted in the forthcoming state election.

Information about the government's new holiday licensing scheme, which is due to start in March, "has not been enough enough for us to hear about it before it's pushed forward," said Mr Hunt.
