Two suicide bombings were carried out in the city of Potiskum on Sunday, one day after the bombing in the neighbouring state of Borno.
The blasts followed what's been described as a massacre in Baga town, where as many as 2000 people were killed at the hands of heavily armed assailants.
Uche Okereke-Fisher, a Sydney-based, Nigerian born lawyer, went to boarding school in Potiskum.
She said it was peaceful then and is devastated to see schools being targeted there now.
“It makes me feel like a part of my life has been taken away from me,” she said.
“Most of the schools, they have actually had to shut now for security reasons. It's really appalling for so many reasons, because what you find is a huge community, most of the people are related somehow. You have very huge families with 30 kids, with four wives, that's the way the culture was, so all of that has been eroded.”
She has lived and travelled across the globe, but feels she may never go back to Nigeria.
“I have no intention,” she said.
“I’m a mother of three. In New York we say, a hero is but a sandwich, it doesn't make me a coward. But I wouldn't go to Nigeria for any reason now, because I don't feel like I am safe.
“I know people who have gone recently, but I also know people who have been gone and who have been killed.”
Augustine Okereafor is from Imo state in Nigeria's south, but he has family living in the northern city of Kano.
From his western Sydney home, he showed SBS a photo of his cousin, his cousin's wife and their toddler.
All three were killed two years ago by Boko Haram gunmen because of their religious beliefs.
“He [was] a pastor, and the wife is an evangelist, so they were targeted,” he said. “They were just shot in front of the house, the wife and husband and little child. The only survivor was the child who was at the back, so it wasn’t a good experience.”
Nigerians head to the polls next month for a crucial presidential election, amid fears violence in the country's north could prevent up to a million people from having their say.
Fred Alale, President of the Nigerian Society of Victoria, said he’s concerned many in the diaspora will be denied a vote.
“We would really like to have a say, be involved in that process,” he said.
“A lot of Nigerians in the diaspora are very passionate about getting involved, having their say in how the country is run.”
That likely won't be possible, with no provisions currently available for millions of Nigerians abroad to cast a vote in absentee.
Global leaders condemn attacks
Nine days after Boko Haram militants stormed Baga town in northeastern Nigeria, bodies remain littered in bushes in the area.
Local authorities have told media it's too dangerous for them to be retrieved.
Farhan Haq, spokesman for United Nations Secretary General Ban Ki Moon, condemned the string of attacks on civilians by Boko Haram.
“The Secretary General utterly condemns this depraved act at the hands of Boko Haram terrorists,” he said.
“The United Nations stands ready to assist the Nigerian government and all affected neighbouring states in bringing an end to the violence, and to alleviate the suffering of civilians with all available means and resources.”
The militants say they're fighting for an Islamic state in the central African nation.
In the Vatican, Pope Francis has also called for an end to the violence, and an end to the practice of kidnapping young girls.
“This is an abominable trade which must not continue!” he said.
“It is a scourge which needs to be eradicated, since it strikes all of us, from individual families to the entire international community.”
More than 200 schoolgirls were kidnapped from a secondary school in the village of Chibok in the country's north east last April.
Boko Haram has since claimed many have been married off to its fighters.
