The investigation into how a young woman died in a freakish fall at a historic military bunker on Sydney’s North Head is still going more than eight weeks after her death.

Annika Ferry, 21, suffered fatal head injuries at the abandoned World War II structure on Blue Fish Point while watching the sunrise with her best friend on June 24.

In the wake of the brilliant engineering student from Balgowlah Heights’ death, authorities closed off the bushland and military fortifications on the point.

The State Government’s National Parks and Wildlife Service (NPWS) confirmed the area was still “closed to public access”.

“There is no formal public access provided to the bushland or fortifications at Blue Fish Point,” an NPWS spokesman told the Manly Daily.

NPWS declined to confirm whether it was examining the structures for faults.

“Ms Ferry’s death is the subject of a coronal inquiry. As investigations are ongoing it’s not appropriate for NPWS to provide further comment at this time.”

In preparing a report for the NSW Coroner, Northern Beaches Police have been trying to determine if Ms Ferry slipped while standing on a section of the 70-year-old searchlight station, or whether a section of its cracked concrete roof gave way while Ms Ferry was gripping it.

A photograph of the popular student, taken by her friend Bec Bennett just moments before Ms Ferry fell, shows her holding on to the edge of the roof while she was standing on an opening in the bunker, facing out to sea.

After the incident NPWS immediately restricted access to the historic military relics on Blue Fish Point which include three searchlight emplacements and an abandoned two-level radar installation, popular with sightseers.

A contracted security guard was stationed at the end of Blue Fish Dr to prevent hikers and anglers accessing a rough bush track, skirting the southern edge of the North Head Sewage Treatment Plant, to the top of Blue Fish Point.

Trestle barriers and a sign stating: “Area Closed. Penalties Apply” were set up.

There is also “Danger Do Not Enter” tape on a historic wall between the national park and the former North Fort military barracks.

Northern Beaches Police crime manager, Mick Boutouridis said police had taken a statement from Ms Bennett and were preparing a brief of evidence from the coroner.
