In WA you need to refer to the Navigable Waters regs and the Western Australian Marine Act.
www.slp.wa.gov.au/legislation/statutes.nsf/main_mrtitle_1046_homepage.html www.slp.wa.gov.au/legislation/statutes.nsf/main_mrtitle_1843_homepage.html The short answer is that if you are in a river/lake, or, within 400 metres (which really isn't that far out on a sail or kite) of the shore in WA you don't need a PFD, flares etc if you are sailing, interestingly in WA the legislation hasn't caught up with kiting yet so my interpretation is that on a technicality those of us on kites need a PFD, bailer, anchor.
I remember hearing a year or so ago that WAKSA were talking to Dept for Planning and Infrastructure to get the legislation updated.
I've cut and paste some of the relevant bits below.
