I have spoken to a number of people in the childcare and kinder area. The opinion I got from all them was the if your child already goes to some form of childcare, then 3yo is not really needed. It is more for the kids who have never been in any form of care so they can learn what to do in a group situation away from their parents. Not sure how many hours your is for, but down this way it is one session of 2 1/2 hours. When I compared that to a full day of child care and what I had been told I decided not to worry about 3yo kinder.

Anyway is it shame that you have missed out on what you wanted.
