Autism Spectrum Disorder (ASD) is a lifelong neurodevelopmental condition that affects how individuals perceive the world, communicate, and interact with others. For many families, the journey toward understanding and supporting a child who may be autistic begins with a diagnosis. But what does that process involve? Who can help? And what can families do while waiting for answers?
At SLCN, we understand that navigating the autism diagnosis process can feel overwhelming. This guide is designed to provide clarity, compassion, and practical advice for families at every stage of the journey.
Autism is a spectrum condition, meaning it presents differently in every individual. Some children may show signs in infancy, while others may not display noticeable traits until preschool or later. Common characteristics include:
Autism is not an illness to be cured, but a different way of experiencing the world. Understanding and support are key to helping autistic children thrive.
Early signs of autism can appear as early as 12–24 months. These may include:
If you notice any of these behaviours, trust your instincts. Speak to a health professional such as a GP, paediatrician, speech pathologist, or psychologist with experience in autism assessment.
In Australia, autism diagnosis is typically made by a multidisciplinary team. This team may include:

At SLCN, we provide comprehensive post-diagnostic support to help families navigate the next steps with confidence.
In Australia, wait times for autism assessments can range from several months to over a year. But you don’t have to wait to start helping your child.
Research shows that early intervention leads to better outcomes in communication, learning, and social development. Even without a formal diagnosis, children under 9 may be eligible for early supports through the NDIS Early Childhood Approach.
Therapies that can begin before diagnosis include:
These therapies can be tailored to your child’s needs and strengths, even before a diagnosis is confirmed.
