Ice and snow that had accumulated since 2002 was removed in 2006:

Significant amounts of ice removal has continued in the Main Hut (2008, 2009, 2010) revealing more of the kitchen and bunks.

The associated impact on the internal environment is yet to be fully understood. Further analysis of corrosion data and additional monitoring are required before firm conclusions can be drawn.

      Nails from the ceiling, bolts retrieved from the workshop collar ties and the results of corrosion monitoring indicate normal to low corrosion rates, not sufficient to affect their performance, and consistent with bolts from the living section (2002).

      Low corrosion of flagpole bolts (2007). Corrosion monitoring should be continued as part of the monitoring plan.

      Heritage objects are in various conditions due to exposure in different micro-environments. Photographic and other evidence indicates that some objects have been moved out of context (2002).                                                                                                                                                                                                                                                                                 Few items have been removed since 1913, and photographic documentation should enable items stored or moved elsewhere in the hut to be returned to their 1913 or 1931 locations.

      Some artefacts and fixtures are clearly suffering due to ice ingress and mould (2007). Conservation of artefacts has helped to stabilise deterioration due to environmental conditions.

Non-historic items have been removed from the Magnetograph House. New timber over-cladding boards obscures the original roof but allows the AAE fabric to remain in place.

      Despite being stabilised in 1997, the remaining wall boards are very thin and are only secured by the ice embedded around the boards.                                                                                                                                                                                                                                                                                                                                          Many cladding timbers have been lost and others have been dislodged. Due the nature of managing a standing ruin, there has been a decrease in the level of integrity associated with the Absolute Magnetic Hut since the last management plan.

      The hut has been stabilised as timber had deteriorated markedly and the structure was on the verge of failure.
