Welcome Richard 😊
I recommend you keep an eye on our Australian Sponsored Job listings and apply when an electrician role is advertised (there are a few available at time of typing).
Sponsored jobs are just like any other job really. You'll need to apply like everyone else and be interviewed.
If you are the best candidate, then you will maximise your chances of being sponsored.
Also, consider registering for job alerts so we can email you when new electrician roles are posted.
Details on how to do this are available here: How to register for sponsored job alerts.
Also, have you calculated your 'points' as you may qualify for a standalone visa if you have sufficient points which will not require a job sponsor.
All the best
