Wedged between a bustling shipping port and a working fishing harbour, the port city of Fremantle, or ‘Freo’ to the locals, was historically Perth’s sister city. These days the two are connected by suburbia and a 25-minute train journey. Wander through the Unesco-listed streets here for convict history, funky street art, and al fresco cafes. It’s where high-end travellers rub shoulders with backpackers, because Freo is eclectic, creative, grungy and refined, with a coastal vibe all of its own.  The streets buzz with the song of buskers, the sidewalks fill with a wild collection of art and the music that floats out from trendy cafés and bars.
