A South Australian man linked to a national neo-Nazi group has fronted court accused of trying to make a bomb.

The court heard police will need at least seven months to prepare their case against the northern suburbs man who has links to a controversial neo-nazi group that promotes hatred and white supremacy.

The accused bomb maker Patrick Patmore, who has been living in suburban Salisbury east in Adelaides north, was arrested in April.

The 32-year-old is accused of possessing a homemade bomb, having instructions on how to manufacture explosive devices and possessing prohibited weapons.

He wasnt keen to elaborate on the allegations on Wednesday, driving quickly away after his first but brief court appearance.

The accuseds bail conditions require him to report to Elizabeth police station twice a week.

A second man, arrested for possessing extremist material, will front court next month.

It follows a series of raids across the northern suburbs of Adelaide.

The case will return to court in December which is how long prosecutors said it will take to gather all the forensic evidence.

At the time of the arrests, the leader of the neo-nazi party, called the National Socialist Network, Thomas Sewell defended the actions of its alleged members.

A harassment campaign against us and our members, theyre not going to shake our morale - this only strengthens us, Sowell said in a video.

Hes since been arrested by Victorian counter-terrorism police on suspicion of armed robbery.
