Moving to Dublin with autistic kiddo

Hello everyone! My husband and I are moving from Finland to Ireland. Our 3-year-old child has been diagnosed with Level 1 ASD, PDA and anxiety. He is very bright and can communicate in 2–3 word phrases/scripts in Finnish, and he also knows some English words and phrases. He tends to shutdown or gets hyper when he is anxious or when demands are put on him. He does have some behavioral challenges, such as low frustration tolerance and frequent temper tantrums that sometimes involve throwing things. I’m looking for guidance on the support and accommodations available for autistic children in Dublin, Ireland . Specifically: What therapies are offered, and how often do children typically receive them? How are autistic children supported in schools? Do they usually attend mainstream schools with a teaching aide, or are they placed in special schools? Any advice or information would be greatly appreciated
