Looking at LBH I dot see the fine markings I would expect if this were A. natalis which doesn't have a woolly thorax as is evident here. The wet rainy weather we've been experiencing across the Monaro also supports Onccopera (genus). Worn, but what forewing pattern I see does also support Oncopera (genus). Probably O. brunneata or O. rufobrunneus but I'm not sure.
