The 1-1 draw kept alive Sydney's slim finals hopes, with Makela sidefooting home in the 93rd minute after Danny Allsopp had given fifth-placed Melbourne the lead six minutes into the second half.</p>
Vitezslav Lavicka's side is six points adrift of the top six and now must win its remaining five games if it is to have any genuine hope of defending its title.
Rejuvenated Sydney, who went into the game on the back of two consecutive wins, came out looking to create chances and take advantage of a Victory side missing strikers Robbie Kruse and Archie Thompson as well as suspended skipper Kevin Muscat.
Sung-Hwan Byun kicked off an explosive 10 minutes for Sydney that saw a flurry of chances, his powerful 29th minute shot forcing a diving save from Victory gloveman Michael Petkovic.

Young gun Petratos, 18, who has just signed a new two-year deal with the Sky Blues, had another impressive display and caused all sorts of trouble for the Victory backline.
Japanese import Hirofumi Moriyasu almost put Sydney in front only for his well-struck effort to strike the base of the post just before the break.
The visitor looked a different side after the interval and its pressure paid off when Allsopp, who has returned to the club following a spell overseas, latched on to a neat pass from Carlos Hernandez and rolled the ball past Liam Reddy.
The Melbourne supporters celebrated their lead by lighting flares in the stands and their side continued to press with Marvin Anglo and Hernandez both going close.
Sydney replied with long range efforts from Shannon Cole and marquee man Nicky Carle and Petratos squandered a great one-on-one opportunity 10 minutes from time.
However, with Sydney's season looking dead and buried, Makela, who was the Finnish league's top scorer last season with HJK Helsinki, scored in front of The Cove for the second successive week after being set up by Carle.
