The hosts tore through their woeful opponents at Manuka Oval and dismissed them for a dismal 86 in the 25th over, as they close in on a 3-0 clean sweep of the 50-over series.
West Indies lost a staggering 6-15 to slump to their second-lowest score ever in one-dayers against Australia.
But it came at a cost for the home side, with Morris leaving the field midway through an over with a side strain that will see him sent for scans.

Morris was playing just his second ODI and had looked threatening with the ball, taking his first two international wickets in his side's stifling performance.
He wasn't the only Australian in hot form, Xavier Bartlett continuing his stunning start to time in the one-day side with a quality 4-21.
That backed up his brilliant 4-17 in Friday's series-opening game in Melbourne.
West Indies were a fraction unlucky to be trapped at 2-38 in the 11th over as Australia's quicks made early inroads.
Kjorn Ottley (eight) was given out lbw to Bartlett and didn't review his dismissal, despite getting what looked like a massive inside-edge onto his pad.
And Marnus Labuschagne then produced a screamer of a catch at point to get rid of Keacy Carty (10) for Morris' first ODI wicket.
But that was where the fight ended for the tourists with the bat.

Captain Shai Hope (four) and debutant Teddy Bishop (zero) fell in quick succession as their innings crashed to 4-44, while a rank shot from Alick Athanaze saw him go soon after for 32.
Opening bat Athanaze was the only West Indian to show genuine grit at the crease and would be disappointed with his poor dismissal, spooning Adam Zampa to deep backward square.
As if things weren't bad enough, a calamitous piece of running that saw Matthew Forde slip over and dismissed by more than half the pitch contributed to their abysmal late collapse.
