Australia wins comfortably by 419 runs to sweep the series against WI.

Stand-in captain Steven Smith successfully won a key toss and decided to bowl on a wicket that was favourable to batting.

Nathan Lyon took his 450th Test wicket as Australia finished off a 419-run thumping over a discouraged West Indies.

After Glenn McGrath and Shane Warne, Lyon is the third Australian bowler to reach the milestone.

Australia increased the number of day-night Tests they have won without losing to 11, with seven of those games taking place at Adelaide Oval.

Marnus Labuschagne and hometown hero Head's 297-run fourth-wicket partnership, which helped Australia's first innings total of 511 for 7, was outstanding.

On a ground with tennis ball-like bounce and erratic movement, a second-string West Indies attack failed to trouble Australia's batting.

Naturally, West Indies had few positive aspects, but opener Tagenarine Chanderpaul, was their lone bright spot. He withstood Australia's attack with 160 runs at a 40-run average.
