Took a while for us to get to the location. We knew that this song was shot in Downtown Melbourne. So, we figured it would be easy to find out the pedestrian bridge because after all, how many such bridges are going to be there in Downtown Melbourne. But to our surprise, we found a really long list of such foot bridges in the Downtown Melbourne area. The fact that there are other much more popular foot bridges in the Melbourne only made our job that much more harder. But finally, after spending a time in Flickr and in Wikipedia, we were able to arrive at this location.

About the location (from Wiki):
Birrarung Marr is an inner-city park between the central business district in Melbourne, Victoria, Australia and the Yarra River. It was opened in 2002. The name means ‘river of mists’ and ‘river bank’ in the Woiwurrung language of the Wurundjeri people, the original Indigenous inhabitants of the Melbourne area. A long ramping footbridge within the park, designed by architects Swaney Draper, links the three terrace levels and provides disabled access.
