A teenager has pleaded guilty to planning a terror plot targeting police during Anzac Day commemorations in Melbourne.

Sevdet Ramadan Besim, 19, from Hallam in Melbourne’s south-east, also allegedly discussed packing a kangaroo with explosives, painting it with an Islamic State symbol and setting it loose on police officers.

Today, Besim entered his last-minute plea in the Victorian Supreme Court over the charge of planning an act of terrorism.

The offence carries a maximum sentence of life imprisonment.

Police had accused Besim of plotting an Anzac Day terror attack in Melbourne last year in which a police officer was to be beheaded.

Besim said he was “ready to fight these dogs on their (sic) doorstep” in online communications with a 15-year-old British teenager, according to court documents previously released to media.

“I’d love to take out some cops,” Besim is alleged to have said.

“I was gonna meet with them then take some heads ahaha.”

Prosecutors have said the British boy last year pleaded guilty to inciting an attack on an ANZAC day parade in Melbourne.

Anzac Day, April 25, is a major annual holiday in Australia and New Zealand marking the first major battle involving troops from both countries during World War One at Gallipoli in Turkey.
