The pair was seen in a white 1999 Holden Vectra sedan, with registration YAU56P, although police say they may also be travelling in a vehicle similar to a Subaru Forester, with possible registration YKP08U.

Police have serious concerns for the boy's welfare and say he is not in the lawful custody of his mother.

The pair is believed to be either in the ACT or in New South Wales.

Police issue amber alerts, an urgent broadcasting system, to seek community assistance only in high-risk child abduction or missing child cases.

Anyone who has seen Phoenix, the Holden Vectra, the blue Subaru Forester or who may have information about his whereabouts should contact police on 02 6256 7777.
