The Wallabies prevented a British and Irish Lions clean sweep of its Australian tour with a rousing 22-12 win in the third rugby test on a night of wild weather at Sydney's Olympic Stadium.

With two key forwards out, the tourists had a mountain to climb, but after their remarkable second Test comeback, anything was possible. They had plenty of time to rest and reassess as play was suspended for 40 minutes due to lightning, with less than three minutes of the second half played.

The Wallabies had thrown away an 18-point advantage to lose the second Test in heartbreaking fashion last week, but learned their lesson.
