Melbourne City, the team that doesn't know how to lose, are the W-League champions after a 4-1 grand final victory over Sydney FC.

Goals from Scottish duo Jen Beattie and best-afield Kim Little set City on their way to adding the W-League championship to the premiership in their debut season.

Kyah Simon replied with a dubiously-awarded penalty to give City a late scare but Beatrice Goad and Lisa De Vanna made the game safe.

The result was deserved, both for their enterprise on Sunday at AAMI Park and their dominance since their admission to the league in October.

Joe Montemurro's side have swept all aside; winning all 12 regular season matches and capping their campaign with grand final success.

Sydney played their part in an entertaining end-to-end decider, but didn't have the same cutting edge provided by City's star imports.

City's opening goal was fashioned and delivered from Scotland.

Aberdeen-born midfielder Little sent in the chance and Beattie tucked it home.

Beattie's towering header was saved by Sydney goalkeeper Michelle Betos onto the post, but the Glasgow-raised defender reacted quickest to poke home a deft finish.

Ten minutes after the break, Little won a paper-scissor-rock battle to take a free kick, and made it count.

From 25 metres out, the 25-year-old curled home to the top near corner beyond Betos at full-stretch.

City were cruising but fell victim to a sucker punch with 20 minutes remaining.

Referee Kate Jacewicz adjudged Beattie's clash with Alanna Kennedy worthy of a penalty, which Simon dispatched well.

Kennedy's audacious cross shortly after needed Brianna Davey's full attention but that was as close as Sydney came to an equaliser.

De Vanna, who troubled Sydney's defence all afternoon, played through 18-year-old Goad to finish the one-on-one.

The Matildas captain was rewarded for her own gut-busting performance, dashing clear of the Sydney defence and dinking the ball home to light up the 4,206-strong crowd.
