Here is a copy of part of an email from Dave Gault of the Occultation Section of ASNSW.

At 10:36pm on Friday 13th, there is an Asteroidal
event involving the mag. 15.8 asteroid 3275
Oberndorfer and a mag. 9.5 star HIP 81169. The path
crosses central NSW in a north to south direction.
Wiruna is on the eastern 1-sigma limit, meaning there
is a slight chance of seeing the event. For more
info see.
