Commonwealth Bank Series, Hobart: Australia 289-8 (50 overs) beat New Zealand 184 (38.3 overs) by 105 runs
Australia thumped New Zealand by 105 runs in the second tri-series one-day international in Hobart.
Symonds hit six fours in his 70-ball innings
Kiwi fast bowler Shane Bond (4-61) took a hat-trick in the final over of Australia's innings.
But the home side piled on 289-8 from their 50 overs, all-rounder Andrew Symonds top-scoring with 69 and wicket-keeper Adam Gilchrist making 61.
New Zealand were then bowled out for 184 in the 39th over, Ross Taylor (84) the only player with a half century.
As Australia clinched victory with more than 10 overs to spare, they gained a bonus point to stretch their lead at the top of the table.
Gilchrist, who scored 60 in Australia's eight-wicket victory over England in Melbourne on Friday, got his side off to a blistering start, dominating opening bowlers James Franklin and Bond.
We've struggled with the bat mainly; it hasn't quite clicked into gear for us; we've tried a couple of combinations and things haven't quite worked
Gilchrist continued to throw the bat after the dismissal of opening partner Matthew Hayden (27) and registered his 48th one-day international half-century.
Spinner Jeetan Patel finally trapped Gilchrist lbw before Australia skipper Ricky Ponting (10) was dismissed cheaply by Mark Gillespie.
However, Michael Clarke and Symonds rebuilt before Clarke was eventually out for 33 after a rash stroke off Bond.
Mike Hussey suffered a rare failure, making just 20, but his dismissal only brought Cameron White to the crease.
The Victorian took an instant liking to Daniel Vettori, smashing the spinner over the leg-side boundary for successive sixes in the 45th over.
White and Symonds remained at the crease until the final over when Bond took centre stage.
His first wicket in the hat-trick over was that of White, the batsman holing out to Craig McMillan on the boundary after making 45 from 32 balls.
Symonds followed immediately, edging one behind, and Bracken completed the set after seeing his stumps shattered.
Bond achieved the 23rd hat-trick ever in limited-overs internationals
Bond's hat trick was the 23rd ever in limited-overs international cricket and he became only the second New Zealander - after Danny Morrison against India in 1994 - to achieve the feat.
But the celebrations were short-lived as New Zealand's reply started badly, openers Brendon McCullum and Nathan Astle returning to the pavilion with just seven on the board.
McCullum fell leg-before to the 12th ball of 23-year-old Ben Hilfenhaus's one-day international debut.
Captain Stephen Fleming contributed 29 but it was the partnership between Taylor and Peter Fulton (37) which gave New Zealand brief hope.
After 32 overs, shortly after Taylor edged a Mitchell Johnson delivery to Gilchrist, the Black Caps had reached 164-4 - the same as Australia at the same stage.
But Clarke removed McMillan with a stunning run out and thereafter wickets fell at regular intervals.
Johnson, Stuart Clark and Symonds each took two wickets in a well-balanced Australia attack.
New Zealand face England at the same venue on Tuesday.
