The "Wildlife Ramp Only" sign is in English and suggests a managed waterfront area. The architecture and the specific style of the stone paving and railings are very characteristic of modern urban developments in Australia. The vegetation, including the deciduous trees, fits a temperate climate typical of southern Australian cities. I suspect this is near a harbor or riverfront in a major city like Sydney or Perth. I am moderately sure of this location.

The stainless steel railings and high-quality stone pavers are very common in Australian public parks and harbor-side walkways. The specific style of the landscaping, featuring tiered hedges and London plane trees, strongly points toward a well-maintained urban park in a city like Sydney. I am fairly confident this is located in the Barangaroo or Darling Harbour area. The atmosphere and vegetation match the temperate, coastal climate of New South Wales perfectly.

I suspect this is in Sydney, Australia. I am quite sure.
