A Victorian grandfather accused of training to fight the Indonesian government as a mercenary in West Papua has had his matter mentioned briefly in court.

Gerard Michael Little, 45, was charged in December with committing preparatory acts for incursion into foreign states.

The slightly built, greying disability pensioner has also been charged with training or performing drills in preparation for the same.

Little was arrested at the Brisbane International Airport as he tried to board a flight to Papua New Guinea, from where he intended to travel to West Papua.

His matter was mentioned in the Brisbane Magistrates Court on Friday, where his lawyer, Lauren Phelps, asked for a one-month adjournment.

She said the crown had recently provided them with two volumes of material they needed to peruse before taking instructions.

Little was not in court for the mention.

The matter was adjourned until February 22.
