Welcome to MSO!
I assume your GPA is on a 4-point scale. You'll need to convert it to a 7-point scale to give us a better idea. Though, with JCU, rurality + written application + interview are the far more important factors than academic performance, so long as your GPA is within the ballpark. Obviously even with your GPA on a 7-point scale, it will still be very difficult for us to give you an idea of your chances at gaining an interview because this will largely come down to the quality of your written application.
My advice would be to start on your written application ASAP so you have plenty of time to perfect it! Best of luck
