1. Job skill-up at your university
If you are considering work outside academia, I suggest taking advantage of the training and support provided to university staff and students. Universities provide detailed training and tools for students in how to work out what sort of job you might get and to apply. I work with people at ANU Careers teaching computing students how to think about a job, as their last assignment before graduating.
2. Business skill-up at your local start-up center
Universities also provide training in business skills. Don't dismiss entrepreneurial training at start-up centers around the universities. Even if you don't want to set up your own business, the training in how to plan, budget and present is valuable. I have taken part in the workshops at the Canberra Innovation Network (CBRIN).
3. Get training and insurance cover from your professional body
Also I suggest looking to your professional body for training and assistance. As an example, the Australian Computer Society provides training and also low cost liability insurance . Keep in mind that if you are going to be a consultant, you or the company you work through, will need to have insurance, which can cost thousands of dollars a year.
4. Teach your students to be professionals, not just academics
In the longer term, as I suggested before COVID-19, universities and supervisors should start educating graduate students first of all for jobs outside academia, as there are very few secure well paid ones in it. If you are supervising a student, I suggest you have an obligation to make it clear to them that they have next to no chance of a secure, well paid job at a university. So encourage your student to first get skills and qualifications for work outside academia. If they are exceptionally gifted in research, they may then consider that, after they have ensured they will not be trapped in the academic system.
