The university-based side put seven goals into the net to record an emphatic result, after losing last week to Melville City.
Rory Binnie and Eddie Tikoft scored two goals each. Bryce Young, Fraser Grant and Jon Krawec also got on the scoresheet.
Dimce Taneski was the lone scorer for Balga.
It took only five minutes for Curtin to get things started, when Young burst down the right-hand side and buried the ball into the bottom corner.
It was Binnie who scored next, when he finished off a sweeping move to double the advantage.
Binnie again scored from some slick passing.
Then Grant got in on the action, when he he ran on to a long kick from Curtin keeper Calum McMulkin, rounded goalkeeper Michael Dudek and tapped into the empty net.
After the break, it was more of the same.
Binnie missed out on his hat-trick by striking the woodwork.
The next goal was the pick of the lot. Tikoft curled the ball effortlessly into the top corner from outside the box, leaving the crowd dumbstruck.
Tikoft then hit the post before scoring his second. Krawec showed the youngster how it’s done as he rounded out the scoring for the night.
