AS the remnant moisture from Ex-Tropical Cyclone Olga makes its journey into New South Wales and South Australia, some areas are picking up their biggest rain in years.
Northwest NSW is welcoming the heavy rain that brought Tibooburra their heaviest falls in three years, picking up 70mm in recent days, already well above their monthly average of 24mm.

This comes as good news as dry conditions have plagued the area with much of the region seeing less than 20 per cent of their average January rainfall.
Unfortunately the heaviest rain had stuck just to that northwest corner so nearby Wannaaring only saw 5mm.
Northeastern South Australia also saw flooding rain with Moomba picking up 75mm in the last couple of days, which is their biggest rain in 11 years and more than they received in all of 2009.
Further south, Arkaroola saw 46mm making it their best rain in four years.
The rain will spread further south in the Flinders before this moisture is dragged east.
Some areas over eastern SA and western NSW could see another 40-50mm over the next 24 hours.
