Fernando Alonso has conceded that there are "still jobs to do" ahead of Australian Grand Prix qualifying after a disrupted day of practice at Albert Park.
The Spaniard finished top of the timesheets having posted a one minute, 18.887secs with a set of medium tyres in second practice.
But teams will enter Saturday with a lack of representative data having lost time in first practice through two red flag periods - the first due to a loss of GPS data across the 10 teams.
Rain then fell within the first 20 minutes of FP2, meaning no qualifying simulations or long runs were able to be completed during the time period this weekend's critical sessions will be run.
