Firstly, it's not a pulsing kick, it's more of a pulsing bass. This is done by placing a bass exactly halfway between kicks. If you want to make a Melbourne bass, simply find the moog bass preset in Sylenth. Next, find another bass preset. With one of the presets, EQ it so you can't hear the low end of one of the basses. That's pretty much how you make a Melbourne Bounce bass. If you've got any more questions, shoot me a PM here!
