The WIN Sports Stadium was undergoing reconstruction at the time of this shot, as a result of which half of Harbour Street running alongside it has been closed off. This shot was taken just before dawn. The safety barriers on the other side are illuminated by the headlights from a vehicle coming down Stewart Street to the left.
Addendum: My personal opinion is that Facebook and all other members of the Meta group are disgusting, sociopathic organisations that steal other peoples' intellectual property (including the images in this gallery) despite being explicitly denied permission to do so.
