This Sunday 4th November from 10am- 3pm at Samson Park, Fremantle it's the Children's Fiesta, part of the Fremantle Festival (and you can pop down to South Terrace afterwards for the Coffee Festival!). It's a free event with hands on activities, stalls, entertainment, live music, and families can "bounce, climb and paint their way" through the day! It ends with a free jazz concert when the sun goes down so bring a picnic blanket -
