Why is it that all the figures in the financials are only up to 30th September 2017?

Also, how can they 'restore the carrying value' of a tenement they had already written a make believe figure off of. Looks like they needed to add a few positive $$'s to the expense column so it won't look so bad in the next quarterly report which I thought should be quoted here.
"The Company has chosen to restore the original carrying value of the West Guadalcanal asset and reverse the full impairment amount of AU$2,817,000 as the value is likely to be recoverable through future exploration activities."
