I’ve recently gotten my full electrical license and it’s a long process.
To be honest the future skills assessment is not difficult if you’re a sparky, even if you do muck something up I think you’re allowed to go and correct it. I did mine in Sydney. You will have to study a bit for the theory side if it’s been a while, health and safety, AC/DC theory, safe isolation, fault finding, motor wiring DOL starter both 3 phase and the control circuit.
Make sure you have a go at the practice paper future skills provide you.
The capstone is a lot more difficult.
