Feel-Good Fun for Your Teens! Youth Week at Brookvale. Celebrate Youth Week with headspace Brookvale at Feel Good Frequency. A vibrant, feel‑good afternoon focused on youth wellbeing, creativity and connection. Designed by local young people themselves, this relaxed event invites teens and young adults aged 12–25 to discover great Northern Beaches youth services, meet new faces and soak up positive vibes in a welcoming, community driven space. A lovely opportunity for mums to point their young people towards something supportive, local and genuinely uplifting.
