All-rounder James Hopes took career best figures of five wickets for 14 runs as Australia came through some nervy moments to beat Ireland by 39 runs in a one-day international in Dublin on Thursday.
World champions Australia, in the first match of their British Isles tour, were held to 231 for nine in 50 overs at Clontarf.
Opening batsman and wicketkeeper Tim Paine, only on tour after Brad Haddin was ruled out with an elbow injury, top scored with 81.
Ireland openers William Porterfield and Paul Stirling then shared a stand of 80 in 11 overs to spark thoughts of a shock win.
But Ireland's innings fell away with medium-pacer Hopes doing the bulk of the damage.
Australia begin a five-match one-day series against England at Hampshire's Rose Bowl ground on Tuesday.
