James: look up images of skyscrapers in Australia, and find something that looks familiar
Ryan: look through major Australian cities in Google Maps satelite 3D view, and find something that looks familiar
After some time, neither option presented anything promising.
We tried searching for unique objects in the image, such as:
- building with the dome
- curved glass skyscraper
- traditional hut on the balcony
- wavy metal roofing Tried adding "Australia" at the front of the search, and tried different key words, but no luck.
The brown building had a 3 letter (or 4 letter) abbreviation that seemed like ANC or AVE or something similar. When I searched ane building australia, I realised it was actually saying ANZ.
From there is was fairly trivial to work out the apartment location where the photo was taken.
The required street was not the one directly below the apartment, nor was it one of the neighbouring streets: little_lonsdale_st, lonsdale_st, hardware_st, finlay_alley, queen_st, timothy_ln, heape_st
Turns out it was the street behind the apartment -_-
