Wallabies coach Joe Schmidt says even he was caught off guard after his team suffered an unexpected injury crisis that forced them to use four captains in Saturday night's 30-12 loss to South Africa.
The Wallabies only trailed 11-9 at half-time at a rain-drenched Optus Stadium in Perth, but the Springboks scored three tries from rolling mauls in the second half to secure the bonus-point victory.

Australia lost skipper Allan Alaalatoa and fellow prop Angus Bell at half-time after the pair suffered head knocks leading into the break.
Veteran prop James Slipper was brought on to take over the captaincy for the second half, but his night lasted just eight minutes before being concussed.
That meant the captaincy was transferred to halfback Nic White, but when he was brought off a short time later, the skipper duties fell to forward Harry Wilson.
Compounding the Wallabies' woes was the fact that hooker Josh Nasser was also forced off early in the second half.
Schmidt, who coached Ireland from 2013-2019, said having to rotate the captaincy so many times during the match was hard to deal with.
"No disrespect to Harry, but it's a little bit destabilising when you work your way through and you get to your fourth captain," Schmidt said.
"Harry wouldn't have had the expectation that he was going to be leading the side when we started the match."
The Rugby Championship loss in Perth followed on from the Wallabies' 33-7 defeat to South Africa in Brisbane.
But Schmidt praised his team's fighting effort at a wet Optus Stadium, believing they showed grit and determination in the face of adversity.
The Wallabies will now front up for two tough Tests against Argentina in Argentina, starting on September 1.
Prop Taniela Tupou, who recently flew to Tonga for his father's funeral, will return in time for the trip to Argentina.
Nick Frost (concussion) and Jeremy Williams (concussion) will also be available for selection, but inside centre Hunter Paisami is in some doubt with a leg injury.
Schmidt said Will Skelton wasn't realistically in the selection frame given the powerful lock is tied up in pre-season training with his Top 14 side La Rochelle.
"I continue to have conversations with Will," Schmidt said.
"But it is complicated to get someone like Will back out of the Top 14 lead-in ... they're in pre-season training."
