Is it possible to not use a car?

Hi! Loving all your visuals and recommendations! I’m planning a solo trip to Perth soon and would love to hear from you. As a solo traveller, how do you arrange your transport to places like the blue boat house and rainbow containers? Do you join tour groups or are these places easily accessed by public transport? What are some recommended hostels/hotels to stay at? Isit safe to walk at night for a female? Thank youuuu!

Hi may I know the name of Air Bnb you booked? Thanks :)
