Two teenagers have pleaded guilty to plotting a massacre at a Riverland school in South Australia.
Just days before their trial was expected to begin, on Friday the pair entered a guilty plea to aggravated threatening life after the more serious charge of conspiracy to murder was dropped by prosecutors.
The boys, aged 17 and 19, plotted to kill as many fellow students and teachers as they could at a Riverland school in November 2017, 7News reports.
In shocking evidence heard at a previous court date, the boys had planned to use guns, knives, homemade weapons and explosives in the attack.
They were also prepared to end their own lives.
It is understood one of the boys had formed an obsession with the Columbine school shooting in the US where in 1999, two teenagers rampaged through Columbine High School in Littleton, Colorado.
Twelve students and a teacher were shot dead while more than 20 others were wounded before Eric Harris and Dylan Klebold took their own lives.
Outside of court, relatives of the two teenagers wouldn't comment.
They will remain in custody and be back in court for sentencing submissions in April.
