Transcript at this TEDxSydney talk video, at 4:10
You know, I'm from Brisbane, which is a great city to live in.(Applause and shouts from the audience) Yeah! All right! Most of Brisbane's here. That's good. (Laughter)
I assume the transcript above provided by the official website is accurate.
I think Brisbane in the transcript refers to the city, not the people in that city, right? As to Most of Brisbane's here, I have two guesses:
1, Most of those who are applauding are from Brisbane.
2, Most people from Brisbane have come here.
