"I saw the pictures and we read the papers, about the tsunami and what actually happened. It really did touch a cord with me and I wanted to come over here and help," Warne was quoted as saying by SNTV after he arrived in Colombo on a three-day visit.
Warne said the Galle cricket stadium which was devastated by the December 26 tsunami was special to him.
"It was my comeback Test match, my 500th wicket there - a pretty special moment for me. So, when I saw those pictures, I wanted to help," Warne said.
Warne is putting aside his spin rivalry with Sri Lanka's Muttiah Muralitharan to provide aid to victims of the tsunami.
Warne will join Muralitharan during a visit to Galle in southern Sri Lanka on Wednesday to see where he can direct funding from his charity for the rebuilding programme.
The bowlers will also conduct a joint coaching clinic for 200 young spinners from schools affected by the tsunami, the cricket board said in a statement.
Warne and Muralitharan, longtime rivals on the cricket field, have exchanged the record for most wickets in Test cricket over the last 12 months.
Warne leads the standings with 566 wickets from 120 Test matches, while Muralitharan is second on the all-time list with 532 wickets from 91 matches for Sri Lanka.
