Sri Lanka conquer Aussies after 17 years.

​Galle: Off-spinner Dilruwan Perera bagged six wickets to fashion Sri Lanka's historic series win over Australia on Saturday as the world number one side suffered a humiliating 229-run loss inside three days in the second Test in Galle.

Australia, chasing a challenging 413 for victory, were bundled out for 183 after lunch as Sri Lanka, who won their last series against the visitors in 1999, took an unassailable 2-0 lead in the three-match rubber.

Veteran spinner Rangana Herath set up the win for the hosts with his maiden Test hat-trick which helped dismiss Australia for a record low of 106 in their first innings.

Australia faltered in their second outing as well after Perera, who registered his career-best figures of 6-70, sent the visitors packing in just 50.1 overs as the Sri Lankan players went into a celebratory huddle.

Overnight batsmen David Warner and skipper Steven Smith offered some resistance with their 51-run fourth wicket partnership but both of them fell to Perera's guile.

Brief scores: Sri Lanka 281 & 237 bt Australia 106 & 183( D Warner 41,R Herath 2/74, Perera 6/70)
