At least two people who attended last week's Big Dream Event by Unltd have tested positive to COVID-19.
More than 650 people attended the charity fund raising event by the industry's social purpose organisation.
NSW Health has been texting those who attended, warning them to be alert for coronavirus symptoms.
Unltd: "Both guests started showing symptoms on Monday, got tested (one on Monday and one on Tuesday), and advised us of their positive results today (Wednesday).
"Based on advice from NSW Health, a person who tests positive is required to notify anyone they have been in contact with in the two days before they got sick. Based on this advice, the Big Dream event would not be included in the formal notification process, however we wanted to inform all guests as a precaution, and to enable you to make any necessary personal decisions."
