The sign says "Caution Wildlife Ramp Only," which is written in English and suggests a park or waterfront setting. The architecture is modern, and the landscape features deciduous trees and stone paving, typical of a temperate climate. The overall aesthetic and the specific style of the signage point strongly toward Australia. I suspect this is a waterfront area in Sydney, possibly near the Parramatta River. I am fairly confident in this assessment.
