Welcome to Geekhack!
Yes most stuff is in the US, or the UK. And expect around 3 weeks or so for deliveries to arrive (sometimes a bit less from the UK, for some reason). Plus silly shipping cost too.
But with a little patience, things aren't too bad. And we have MechKB here too, they even stock RealForce keyboards! In Sydney, but, IIRC. PCCG is generally the place to go here in Melbourne.
