sorry, seeing as you asked if it was the same as on a vz, i assumed you had done a vz before.
1. open glovebox
2. remove anything inside glovebox, or itll do it for you at step 4
3. remove 2 rubber stoppers by pushing them towards the front of the car and inwards, they just slide off.
4. open glovebox further, at this point if you forgot to remove everything, it will fall out onto the car floor.
5. pull towards you on both sides. take your time, dont be too forceful or you will break the plastic clips, but if you do they can be easily sourced from holden as said above.
