A long story but after taking my child out of her then primary school during Year 3, I applied to another school nearby, not even thinking she would get in. After a couple of weeks, received a letter saying we had gone straight to No. 1 on the list as we were "12 minutes walking distance" away from the school. 12 minutes walking distance is not that far so I'm not sure what the maximum walking distance is. Hope everything works out for you.
