The child pornography case against former ABC presenter Andy Muirhead is to be tested in a preliminary proceeding, the Tasmanian Supreme Court ordered today.

Muirhead, 34, has pleaded not guilty to two charges - using the internet for child pornography and possessing child exploitation material.

The former host of the popular ABC TV series The Collectors was charged last June after Australian Federal Police officers searched his home and seized his computer.

Following a series of lower court appearances, his case was transferred to the Supreme Court.

Justice Peter Evans today ordered a return to the Court of Petty Sessions for a preliminary proceeding on August 1.

By consent, Muirhead did not appear in court and his bail was continued.
