Jess Fishlock impressed her quality again - her two strikes made the difference in Melbourne City's 2-0 defeat of Sydney FC to claim their third consecutive W-League championship at Allianz Stadium.

Sydney started the up-tempo encounter brightly, Chloe Logarzo and Teresa Polias standouts for the Sky Blues, but grand final experience won the day, and there's few more experienced, or devastating than Fishlock.

The Welsh international opened the scoring after Sydney goalkeeper Aubrey Bledsloe was -seemingly unintentionally - brought down after a goalkick. Sydney then lost the ball in a dangerous position, with their keeper in no-man's-land, and Fishlock was on hand to chip Bledsloe and gift City the advantage. 

As both sides tired, the match became more cagey, with long balls the preferred option. 

Eventually, it was another piece of Fishlock brilliance that cemented the Championship. Her second-half free kick required a diving save from Bledsloe, which rebounded to a cool Jodie Taylor with no Sydney defenders in sight. 

Among a host of other records, City become the first Australian football club to win three grand finals. If their form, and the guidance of coach Patrick Kisnorbo is anything to go by, they may not be finished yet. 

"It's fantastic, it was hard, Sydney are a fantastic team, we knew today was going to be extremely hard," Fishlock said.

"We knew we could hurt them and that's exactly what we did today. I have nothing but love and pride for these girls.

"This will never be repeated. What Melbourne City has done for women's football in this country won't be appreciated.

"Respect what these girls have achieved, because it will never happen again."
