Both myself and others in this position are not eligable to apply for this position end of, we have been told. It has just been laid out to us that we are with the company to reach our career goals, that is all we should be concerned with.
Why are you not eligible to apply? Are they seeking staff with more experience than you have or with more qualifications? If a job is publically advertised, any qualified member of the public is entitled to fair treatment. While it might appear that the new staff are doing the same job as you, it would be worth checking the requirements for the new candidates and seeing if they are looking for more experienced/qualified people. If they are, they are justified in offering higher salaries etc.
