Cape Town - They won't be meeting on the field this month, but the Springboks and the Wallabies have clashed in a different way this week.
Both nations are on their end-of-year tours of the northern hemisphere, and there would have been some wide eyes when it was revealed that both sides had booked to stay in the same London hotel!
The Wallabies take on Wales in Cardiff on Saturday while the Springboks take on the Barbarians at Wembley Stadium.
According to the Daily Telegraph website, the Wallabies had booked into the Lensbury Hotel with the assistance of World Rugby while the Boks were booked into the same hotel through the Barbarians organisation.
The Wallabies are only expected to stay in the hotel until Wednesday before they head off to Wales, but this week has been a bit of a nightmare in terms of scheduling with the Aussies and the Boks having to work around each other's gym schedules.
The Wallabies will also face Scotland, France, Ireland and England on their Grand Slam tour while the Boks' only Tests come against England, Italy and Wales.
