South Perth Scented Garden

About 350m from the Mends Street Jetty is the Scented Garden, which offers some tables and benches, a playground and accessible toilets. There is parking available (free for the first hour) or you could park at the Mends Street Jetty parking and use this as a walk. The sculpture along the foreshore is a good landmark. You can see the toilet block from there.
This could also be a good place to get away from the hustle and bustle to find a quiet spot. There are some shelters and BBQs in the park as well.
