The Grill like a restaurant link above is great. Read that and you will be fine.
Basically, sear the steaks on either side in a very hot skillet, saute pan etc for 1 minute to get a good crust. Then transfer them to a pre heated 500 degree oven into a pan (also pre-heated) and leave them for 8 minutes or so. No need to turn the steaks.
If your Saute Pan or skillet can be moved straight to the oven even better.
The main things to get right are the timing of the rest of the meal so you dont have to leave the steaks in the oven. Also, make sure you remove the steaks a little early as they will keep cooking in their own heat. I made that mistake.
Vegemite - Just say no!!
