"I am thrilled to be here and pretty much looking forward to the challenges that lie ahead," said Moody, who arrived on Saturday evening from England, where he was coach with Worcestershire.
"I would like to get familiar with the players around, not only those with the Test side but also those in the 'A' side and others," said the 39-year-old.
"I am looking forward to working with them and hopefully having a very successful time," said Moody, who was a member of the Australian sides that won the 1987 and 1999 World Cups.
"There are some world-class cricketers here in Sri Lanka, and hopefully we can continue to produce more such players in the future," added Moody, who played eight Tests and 76 One-dayers.
Moody is reportedly the highest-paid Sri Lankan coach ever and the fourth Australian to take over the national side after Dav Whatmore, Bruce Yardley and John Dyson.
Sri Lanka are scheduled to play a two-Test home series against the West Indies next month followed by a tri-series also featuring India.
