Children from a remote Pilbara school in Western Australia have drawn pictures and written heartfelt letters of support to the people of Grafton where the alleged perpetrator of the Christchurch massacre grew up.

A bundle of handwritten letters and drawings arrived on the desk of the Clarence Valley Council Mayor, Jim Simmons, who described it as a "touching gesture from beautiful children".

The children from Nullagine Primary School, which has only 30 students, had seen images on TV following the shooting and their teacher, Violet Hogan, fielded many questions from them.

Ten-year-old Shiloh wrote, "I want everyone to feel better in their town. We in Nullagine are sad about this trouble".

Twelve-year-old Weston wrote, "It's not your fault. Still love your town".

Sonia, 12, wrote, "Try to feel better. I am sorry", and 11-year-old Rickira wrote, "Look after yourselves. Get that sadness away".

Students affected by New Zealand's tragedy

School principal Greg Yeo said the school had a focus on building empathy in its students.

"We do a thing called Aussie Optimism and some of it is to do with having empathy for other people," he said.

"The kids were shocked when [the massacre] happened.

"I think the kids were very upset that this … man actually came from Australia."

Among the drawings that the children sent to Grafton were images of the distinctive, ochre domes of the Pilbara region.

Nullagine is very remote, located 300 kilometres inland from Port Hedland in Western Australia and 200 kilometres north of Newman.

There is 70km of rust-coloured dirt road on one side and 100km on the other.

When floodwaters from Cyclone Veronica inundated the region, the town was cut off.

"With Cyclone Veronica blowing … the other day, our roads are closed at the moment so the trucks can't come in and wreck them," Mr Yeo said.

English is not the first language

All of the students at the school are Indigenous and none spoke English when they started school.

"The kids speak Martu as their first language, and then they'll speak Aboriginal English, and they come to school and really have no English to start with," Mr Yeo said.

He first arrived in Nullagine four years ago and said he now had a close relationship with the community.

Mr Yeo has seen the students' attendance levels rise as well as their language skills.

Many of the children also wrote messages of love to a New Zealand grandmother who they saw weeping on TV news segments.

Troycina wrote, "Dear Grandmother. I hope you will feel better soon. Sorry for you and your family".

"That makes these kids really upset because they revere their elders and they hate seeing things like that," Mr Yeo said.

"There's a lot of compassion in their letters, thinking about people who were suffering. A lot of love has gone into their letters."

The children's heartfelt letters have touched the people of Grafton and made their teacher, principal and community very proud.

"We only have 30 kids, but I tell you what, they're 30 great kids, they really are. They're all very happy here," Mr Yeo said.
