A BAN on using mobile phones during school hours has started for all public school students in Victoria.

The bans are an effort to prevent distraction and curb cyberbullying.

Swan Hill College posted their new mobile phone policy on Facebook last week.

The policy states a student who chooses to bring mobile phones to school must have them switched off and securely stored during school hours.

Victoria last June was the first state to commit to a ban for all its state school students, with WA and Tasmania following suit later in the year.

NSW has committed to a primary school ban, which flows from a new policy starting this week, after piloting the measure at 22 schools last year.

The policy is to provide advice to high schools on students using digital devices, but ultimately leaves it to them to decide whether a ban is necessary.

There will be restrictions in NSW primary schools, but they are being given a one-year grace period to hash out the details.

Federal Education Minister Dan Tehan has encouraged states to sign up to a ban through the Council of Australian Governments.

Victorian Premier Daniel Andrews believes the state is ready for the measure, even if it is not universally popular.

"We want our kids focused on learning, not on Snapchatting and texting and whatever else you might do on a mobile device," he said on Monday.

"This is a pretty simple thing.

"It's something parents have called for, many teachers have called for."

All the bans include potential exemptions for educational purposes or students with medical conditions.

Swan Hill College principal Andrew Sartori previously told The Guardian the school had already implemented a ban of their own.

"We do think that phones are a distraction, but they can also augment education at times," Mr Sartori said.

"I think plenty of our teachers use it in a beneficial way in education.

"But the ban needs to be consistent and there needs to be rules around when phones are used and why they're used. It just can't be used for open slather."
