Sydney FC extended its unbeaten streak at home to 26 games when it beat last-placed Wellington 4-0 in the 19th round of the A-League.

In front of new Australia coach Bert van Marwijk, Sydney overwhelmed a disorganized Wellington with goals to Alex Brosque, Adrian Mierzejewski, Milos Ninkovic and David Carney.

Van Marwijk was also a spectator as second-placed Newcastle beat the Melbourne Victory 2-0 to stay nine points behind Sydney and seven points ahead of Melbourne City, which plays Brisbane on Sunday.

Newcastle moved closer to securing its first finals berth since 2010.

Adelaide moved clear of the Victory in fourth place with a 2-1 win over Perth.
