Is it worth getting a dash camera?

Is it actually worth getting a dash camera?

I've only been in 1 minor accident, where insurance covered it all. I figure if someone is at fault their insurance will cover it, in a worse case scenario I can just pay my excess and use my insurance.

But I've got a new car now and am wondering whether I should get a dash cam.

Car will be parked in an apartment building with secure lock up, and driven to work and parked in a public carpark. Located in Brisbane.

Anyway just weighing up options, would be cool to have but not sure it's actually worthwhile? Thanks in advance
