As had become normal in 1988, qualifying was the domain of the McLaren-Hondas. Senna and Prost easily led the time sheets on both Friday and Saturday, with Prost initially fastest on Friday with a 1:18.179 lap, 0.153 ahead of his teammate. The pair traded pole laps in the second qualifying session, with Senna doing his usual act of snatching pole on the last lap of qualifying with a 1:17.748 lap, only 0.132 in front of his teammate, but 1.7 seconds faster than the next fastest car, Nigel Mansell in the Williams-Judd. During qualifying Senna was hampered by a sprained left wrist having injured it during a game of beach soccer in Bali where he had taken a small holiday after winning the championship in Japan. His injury was such that there was speculation the teams test driver Emanuele Pirro would drive in his place, but the new World Champion refused to be sidelined and took his place in Adelaide, though he admitted that driving the MP4/4 on a tight, bumpy street circuit while nursing a sprained wrist was hard. Prost on the other hand had spent his time between Suzuka and Adelaide playing golf at a resort in the Australian state of Queensland. There was also speculation that Honda would run their V10 engines (intended for ) in Adelaide instead of the V6 turbo. However, team boss Ron Dennis explained that racing the V10 was never part of the 1988 plan, and that with the RA168-E proving so dominant, Honda wanted to finish the turbo era on the highest possible note.
