Beginners: Please, the area where these shots were taken (Goschs Paddock) is not suitable for beginners to fly kites. Hazards include the usual pedestrians, bicycles, and cars but also trains, trams, and professional athletes. Flying a kite safely in this area requires knowledge of weather, kite handling, and local conditions.
You can also see a bit of the Melbourne Cricket Ground to the right in the second photo.
It turns out rugby goals are hollow at the top. Or at least this one is.
