You can get the additional materials from OET itself.The information is available in the website
www.oet.com.au
plz read thro the thread so that you can know what is being asked in the examination.You can also get some idea abt how the test was conducted.OET sends samples to the candidates few days before the test.I am sure that everyone can crack OET as the english is simple & doesn't involve complex words.plz read all the posts relevant to that in this forum.
ALL THE BEST FOR THE EXAMS.I heard from one of the doctors who appeared for the OET that he got the material from one of the city common libraries in Australia.But I AM NOT SURE WHETHER IT IS CORRECT.Plz check if possible.ALL THE BEST FOR PEOPLE APPEARING FOR OET ,ADC Preliminary & clinicals
