Australia's 4x100m freestyle relay team moved safely into Sunday night's Olympic final as James Magnussen's final leg secured top spot in qualifying.
After questions as to whether the 100m freestyle champion would swim in the heats or be saved for the final, Magnussen dusted off the cobwebs for his London campaign as he brought the team home in a handy 47.35 seconds.
Cameron McEvoy, James Roberts, and Tommaso D'Orsogna had put Australia into second position behind the US heading into the last 100m of their heat.
But Magnussen gradually eased his way into first spot as Australia clocked three minutes, 12.29 seconds to finish ahead of the US (3:12.59) and Russia (3:12.77)
Australians Matt Targett and Eamon Sullivan did not swim and will likely swim in the final.
