what is leo cussen?
I specified 'decent' law student. 12000 students from every single law school with about 30 pc not applying for law jobs. I'm specifically talking about people at usyd/unsw/umelb/monash and those who actually put in solid effort and are somewhat talented in law (i.e. at least d wam). That's around 25pc of usyd cohort. Which is 60-70 people. Most of them will have a clerkship. You can't expect to be average and land a clerkship in law. That doesn't make it a bad field to go into. Everything else is the same
Leo Cussen is a Practical Legal Training provider... Do you even law, bro?
Whether you get SWT or not, you will still have to deal with either them, College of Law or the ANU PLT program... Even in that circumstance you still have 9600 people applying for what is around 1200 entry level legal jobs annually (a bit of a cynical worst case scenario, but it is not unrealistic)...
But yes (to answer the OP's questions), Law students do have scope in terms of employment... You can move off into a number of fields, which include (but are not limited to): Policy and Research, Government, working with the Judiciary, Police, Corrections, Human Resources, etc... You are not necessarily confined to being a Solicitor (It's probably best to keep your options open and elect to do a double degree as a plan B, so to speak)...
Competitiveness is not necessarily centered around your marks (although it does play a small part)... To be competitive, keep yourself occupied during your studies (work/volunteer within the legal profession or any other profession where you can gain relevant skill sets to the profession, retail actually makes you attractive to an employer), etc...
