This portal is located on a kindergarten. If you look at it in Street View you can clearly see that it says "Boroondara Kindergarten"
Reason for rejection as per the OPR rules:
Use for Portal Candidates that are on the grounds of a primary, secondary, or high school. This also includes locations that may be a daycare or childcare center.
A kindergarten is a facility for childcare and education (prior to commencing primary school).
It was located outside and safe access but justified what Oscar has said Genuinely sad it got removed but I will accept it.
I was going to delete the post because I was informed on messenger that it was impossible to restore.
Any portal even on the exterior wall of a school is invald.
