A review into the search for missing woman Esther Marie Wallace has concluded that the operation conducted at Mount Canobolas, near Orange in central-western New South Wales, was appropriate and consistent with accepted search-and-rescue practices.

The findings come after concerns were raised by members of Wallace's family regarding aspects of the search effort following her disappearance. Family members had questioned whether additional resources or different search methods could have been employed during the operation.

Authorities examined the circumstances surrounding the search, including the deployment of personnel, the use of available technology, search strategies and decision-making processes. Following that assessment, officials determined that those involved acted appropriately based on the information available at the time.

Wallace disappeared in the Mount Canobolas area, triggering a major search effort involving NSW Police, specialist rescue personnel, volunteers and other emergency services. The rugged terrain, dense vegetation and changing weather conditions presented significant challenges for search teams throughout the operation.

Search-and-rescue specialists used a variety of techniques in an effort to locate Wallace. These included ground searches, aerial reconnaissance, mapping technology and coordinated sweeps of areas considered most likely to contain evidence of her movements. The operation involved substantial resources and many hours of work by trained personnel and volunteers.

According to the review, search managers followed recognised procedures designed to maximise the chances of locating a missing person while ensuring the safety of those participating in the operation. The assessment found no evidence that established protocols had been ignored or that significant opportunities had been missed.

The findings may provide some reassurance to those involved in the search, many of whom dedicated considerable time and effort to the operation. Search-and-rescue incidents in remote and heavily vegetated areas are often complex, requiring difficult decisions about resource allocation and search priorities.

Despite the review's conclusions, the disappearance of Esther Marie Wallace remains a deeply distressing matter for her family and friends. The case has continued to attract community attention, with many people hoping for answers regarding her whereabouts and the circumstances surrounding her disappearance.

Community members across the Orange region have previously rallied in support of search efforts, highlighting the strong local response to the case. Volunteers assisted authorities during various stages of the operation, reflecting widespread concern for Wallace and her loved ones.

Authorities have reiterated that reviews of major search operations are an important part of ensuring accountability and identifying opportunities for improvement. Such assessments are commonly undertaken following complex or high-profile missing-person investigations.

While the review found the search was conducted appropriately, investigators continue to encourage anyone with information relevant to Esther Marie Wallace's disappearance to come forward. Even small details may assist ongoing inquiries.

The case remains an emotional one for the community, with family members continuing to seek answers and hoping that future developments may provide clarity about what happened.
