One of two brothers arrested in terror raids in Melbourne's north allegedly bought a knife on Wednesday, which police say was in preparation for a terrorist attack.
Aran Sherani, 19, and his 20-year-old brother Ari Sherani faced Melbourne Magistrates Court on Thursday after being arrested by counter-terror officers.
Both are facing charges of attempting to engage in a terrorist act over an incident at Humevale, north of Melbourne, on February 21.
Aran Sherani is facing three additional charges, including intentionally causing injury to an unnamed person in Preston on March 9.
Court documents reveal Aran Sherani is also accused of knowingly being a member of terrorist organisation ISIS and allege he purchased a knife at Epping on Wednesday in preparation for a terrorist attack.
The brothers were among three people arrested in Wednesday's raids. A 16-year-old boy from Pascoe Vale was released without charge.
The older men each faced court by videolink on Thursday and did not apply for bail.
Aran Sherani's lawyer Sarah Condon said he had no prior convictions and this was his first time in custody.
She said for those reasons and the nature of the charges he would be vulnerable behind bars.
Louis Dean said the same applied for his client, Ari Sherani.
They're due to return to court on July 20.
