Ok, the titles you are using on different pages are technically scary and almost identical... Google wants the titles to be more unique on different pages.... these titles are coming probably because its hard coded and added after the content. My advice would be to contact your webmaster and ask them to remove the hard coded title and the issue of duplicate title will automatically be resolved... Try to limit your title within 65 t o59 characters. If you are experiencing a duplicate content issue this must be because most of your part of the page is empty and identical to others... For example: http://www.newmanshs.wa.edu.au/articles/events/mining-alliance-program-map-pit-to-port-excursion and http://www.newmanshs.wa.edu.au/articles/events/country-week Have almost 2 to 4 lines of content and rest of the page is similar to each other.... I would advise you to add more content in it so that it becomes more unique!
