On a prosecution under this section:

(a)

it is not necessary to show that the accused person was guilty of a particular act tending to show an intention to prejudice the safety or defence of the Commonwealth or a part of the Queen's dominions and, notwithstanding that such an act is not proved against him, he may be convicted if, from the circumstances of the case, from his conduct or from his known character as proved, it appears that his intention was to prejudice the safety or defence of the Commonwealth or a part of the Queen's dominions; and

(b)

if any sketch, plan, photograph, model, cipher, note, document, article or information relating to or used in a prohibited place, or anything in such a place, was made, obtained, collected, recorded, used, possessed or communicated by any person other than a person acting under lawful authority, it shall, unless the contrary is proved, be deemed to have been made, obtained, collected, recorded, used, possessed or communicated with the intention of prejudicing the safety or defence of the Commonwealth or a part of the Queen's dominions.

(3)

On a prosecution under this section, evidence is not admissible by virtue of paragraph (2)(a) if the magistrate exercising jurisdiction with respect to the examination and commitment for trial of the defendant, or the judge presiding at the trial, as the case may be, is of the opinion that that evidence, if admitted:

(a)

would not tend to show that the defendant intended to prejudice the safety or defence of the Commonwealth or a part of the Queen's dominions; or

(b)

would, having regard to all the circumstances of the case and notwithstanding subsection (4), prejudice the fair trial of the defendant.

(4)

If evidence referred to in subsection (3) is admitted at the trial, the judge shall direct the jury that the evidence may be taken into account by the jury only on the question whether the defendant intended to prejudice the safety or defence of the Commonwealth or a part of the Queen's dominions and must be disregarded by the jury in relation to any other question.
