Australian Army, Navy and AirForce.

I'm currently 18 years old and don't know what to do with my life, I have a passion for IT and see the cybersecurity part of the military attractive, the pay seems good and all(79k after training starting). Can I get some advice or some insight from someone in this program on what a day to day looks like. Don't really want to end up on the Frontline of a war and also unsure on whether I'll regret as the minimum serving time is 6 years. Any and all advice is appreciated
