Schools Not Accepting Practical Placement Students??

Hi, so I’m waiting to hear back from my uni to be allocated to a school to complete my first professional placement in, but so far they’ve gone through my 1st, 2nd and now 3rd preference and not a single school has called the uni back to accept from what I’ve been told. By the way, all three preferences were low SES schools within western Sydney so I assumed a position would be easy to find.

Does anyone know what’s happening? I was so excited to start but now I’d feel super let down and discouraged. Any words of wisdom?
