One of the more interesting places in Melbourne is a famous Graffiti laden street called Hosier Lane!
It's a popular tourist spot and just a stones throw away from Flinders St station. It features a variety of interesting street art that is definitely checking out.
The graffiti seems to change quite often and it seems that every time you go there's always something new.
There are a bunch of great coffee shops and restaurants nearby. Hosier lane is a popular yet slightly unconventional attraction that I would highly recommend checking out!
