Getting into Uni is just like going to a job interview, you will never know if you have gotten in until you get the offer. In saying that, the likelihood of you getting into the course is dependant on the supply of available positions and demand for the course. I would say that if you really want to do this course then definitely put it first and hope that they accept you. If the bonus points you received were from relevant HSC courses then there is a fair chance that you will be able to make the course. I know a lot of people who have not made the ATAR cut-offs for certain courses but have been offered positions over the last few years, so keep calm and know whatever happens it's okay.
