Serena and Thomas, now 9 and 8, were found in the Sunshine Coast hinterland with their mother — nearly 100 miles from where they vanished.

Police say the siblings were “parentally abducted.”

According to Child Find of America, “Missing children can be victims of family abduction, non-family abduction, or they can be runaways. An estimated 203,900 children were victims of a family abduction in 1999. A family abduction occurs when a family member takes or keeps a child in violation of the custodial parent’s/guardian’s legitimate rights.”

While their mother appeared before the Federal Circuit Court of Australia, Harry reconnected with his kids.

They’re now back together at home, rebuilding three years of missed memories.

“Thank you so much for all your support,” Harry wrote to his supporters.

“This is the best Christmas present.”
