Last night, I went to city for watching CelebrateBrisbane River of Light, which is a light show in Southbank. At 9.30pm, the show started. The water fountain spray water like dancing, then there are a number of the spotlights flashing at the same time too. According to their official website, there is some rainbow light too. Maybe, I watched that in the city, that is too far away, I did not any laser at all.
Please be aware there are two nights of the show left! Please do not miss that!
