Qualifying for the Formula One season opener will be completed Sunday after a series of rain delays and darkness prevented the running of second and third sessions Saturday.
A wet first session of qualifying was completed after a half-hour delay, but a succession of delays of Q2 meant it was becoming too dark to hold the remaining sessions.
Both qualifying and race at the Australian Grand Prix begin at 5 p.m. local time to satisfy European television audiences.
Mercedes' Nico Rosberg was fastest in Q1 ahead of Ferrari's Fernando Alonso and Lotus' Romain Grosjean. Among the six drivers eliminated in the session was Williams driver Pastor Maldonado.
