Another notable episode was associated with low and fog partially covering the aerodrome on 18 June 2013. Although the duration of this episode was sixth in descending order of magnitude, it accounted for the third highest number of aircraft expected to arrive. This was due to the weather coinciding with morning peak aircraft arrival times. This weather episode contributed to a serious safety incident. Two aircraft en route diverted to Mildura, and also encountered conditions below the landing minima at that location. This was the subject of ATSB investigation .
