Hey, it's Friday the 13th, I didn't want to push my luck with too ambitious a shot today.
A lot of the larger commercial vessels have departed Sydney Harbour over the years for the bluer pastures of Port Botany to the south. However some are still around, and those ones need a supply of diesel fuel. This nameless fuel barge is one of the ones to deliver it. I'm not sure why she was tied up to this wharf that runs alongside the park though. Perhaps the crew had gone over to one of the sandwich shops or cafes within walking distance to grab a bite of lunch?
