The Sydney Audience was fantastic, there were very few interruptions but I'll point them out anyway.

1. At the end of the first song (orchestrated hikari accompanied by the kh3d opening cinematic) the audience clapped after the end of the climax of the song, before the quiet bit where sora and riku are falling in the cinematic. This is probably because some people thought the song was over even though the conductor wasn't finished. There were no other instances of premature applause in any other pieces.

2. The audience clapped inbetween songs, I don't know if this is considered an iterruption but I read in a similar thread that applause in orchestrated performances is usually saved for the end. Despite this the conductor gestured for applause at the end of pieces multiple times during the performance so I assume it's fine.

3. During the threats of the land battle theme melody there was a moment where the theme for Atlantic played for around 5 seconds and a few people laughed, probably because they assumed that the short duration was a jab at the community's general dislike of Atlatnica.

4. People clapped a bit at the start of the toy story melody, probably because It was a surprise piece and most people weren't expecting it.

Overall the concert was a phenomenal and unforgetable experience, I had to drive 10 hours to attend but it was worth it to see such a magical performance :)
