For reasons unknown, ACARA has not released (and perhaps never will release) the test questions for the May 2011 NAPLAN tests on its website. http://www.nap.edu.au/NAPLAN/The_tests/index.html. Presumably, most schools have access to these questions from copies unused from 2011.
Kilbaha Multimedia Publishing provides detailed suggested answers to the May 2008, May 2009, May 2010 and May 2011 NAPLAN tests. Full NAPLAN catalogue available here.
