GezMeg, I applied for Victoria SS 190 for ICT BA. I got exactly the same reject message as you. As someone above said, they are being very selective.
I then applied to SA SS directly. At the same time, I updated my EOI to make sure I selected SA for SS (have to do this otherwise they will not consider you) Within a week (normal process early March said 2 weeks processing time..not sure how much it is now), I got the SA SS and got an invitation to apply for the visa. I am currently waiting for CO.
Note - SA doesn't require your CV however they do ask for you specify the reasons asto why you want to move to SA. I did some research and put 5-6 points together.
Best of luck.
