ESF Kindergarten Admission Tips Sharing Forum

I would like to know more about the entrance of ESF Kindergarten, as understand it is extremely competitive. My kids was born in Aus last year and holding foreign passport. We speak both English and Cantonese at home. So what should I prepare from now eg interest class, language class, activities etc to get higher chance for admission in 2013 K1 Can current ESF parents share your experience for admission or guys who wish you kids admit to ESF Kindergarten share your plan and activities of preparation? Thankyou.
