Go swimming in the Swan River! Much better in summer though... Lol

I grew up in Fremantle, it's different to the rest of Perth by a huge margin, much older and picturesque. Plus the little creatures brewery is there, you get beer poured directly from the silos :)

I moved over east because there's a big drinking culture so I'd stay clear of places like Northbridge and Perth City at night, lots of drunk violence.

Fremantle at night is great (well, everywhere except metros)

Rottnest island is amazing, get some photos with quokkas while you're there

Margaret River has amazing winery tours but it can get packed with people with little to no class.. look for a place called the Margaret River chocolate factory instead :) it's a few hours drive south if you've got a hire car there

Visit Cottesloe beach and have lunch at dome cafe and you're 80% of the way of becoming an insta-famous Perth fashionista lol, Cott has a lot of shark attacks though compared to most other beaches, head to Scarborough or Trigg if you're into surfing
