Hi Paul
We were in your position 5 months ago. Dont want to put you on a downer bit it is very hard to get anyone to take you on as a TA . My OH was very lucky to pick up job fitting solar panels, because I was checking gumtree practically every hour!! you will probably have notice most jobs say A grade wanted , you just need to keep plugging away and maybe call to a few places. I dont know where you in Perth but there is a company in Bibra Lake called Nilsens who take on TA so I have been told. My Oh has dont the 2 week training so is now onto the assigments and will have to do another 4 day comms course before he can sit the capstone to get his A Grade.....
hope you find something soon
Lou
