Key players Eddie Tikoft and Khaled Salhah helped lead Curtin to victory with the pair well supported by Jonathon Krawec, Carlo Chiellini and Rory Binnie.
A goal to Kelmscott’s Joe Tomlin in the 18th minute sparked a lacklustre Curtin into action, who hit back through a Tikoft header in the 33rd minute.
Curtin then took the lead through a classy finish as Binnie lobbed the keeper when Tikoft sliced the defence open with a sublime through ball.
Kristian Beven then scored 43-minutes in to send Curtin into the half-time break 3-1 up.
Curtin picked up where they left off in the second half.
Salhah smashed the ball home in the 63rd minute before Bryce Young volleyed home a Dilip Thapa cross in the 74th minute.
Substitute Fraser Grant rounded out Curtin’s scoring when he side footed home from close range.
Christian Hogge scored a consolation goal for Kelmscott in the 85th minute, but it was too late as Curtin came out on top, 6-2.
Curtin will travel to Rockingham next week before playing host to Melville City on Friday, May 16.
