Sidhak Singh Arora was due to start prep at Melton Christian College, in Melbourne's north-west, this year.
But his patka does not comply with the school's uniform policy which prohibits students from wearing any type of religious head covering, ABC news reported.

The boy's father Sagardeep Singh Arora said he was surprised the school would not make an exemption for his son.
"I was very surprised in an advanced country like Australia, they are still not allowing us to wear patka in the school," he said.
"On the basis of that they are not giving enrolment in the school. I believe students should be allowed to practice their religion and should be allowed to wear their article of faith," he said.
Sidhak has enrolled at another school, but his parents hope Melton Christian College will be forced to change its policy so he can enrol there instead.
The VCAT hearing was told the college had an open enrolment policy which allowed children of all faiths to enrol.
Former college council member Stephen Liefting told the hearing they were inclusive of people of all faiths.
"As long as they don't wear clothing that promotes other religions," he said.
Principal David Gleeson gave evidence that a number of Sikh students attend the school but do not wear the patka.
