Two sides who are thrilling and perplexing in almost equal measure, Scotland versus Australia in the Nations Championship on Sunday could be described as the Battle of the Unpredictables.
These are two teams that when they are hot, they are very hot, but both have the capacity to fall so far below their ceiling they are left staring up at it from the floor.
Both are coming off chastening defeats last weekend - the Wallabies taken apart by England at Twickenham, and Scotland taken to the cleaners by New Zealand at Murrayfield.
This is a fixture that stokes the fires of Scotland's Australia-born captain Sione Tuipulotu, but making amends for that second-half no-show against the All Blacks is providing the primary motivation.
"It is always hard to watch the footage back after a defeat like that where we missed some big opportunities and let ourselves down in certain areas," Tuipulotu said.
"As a group, we have confronted that and I've been very proud of the boys in terms of how they have rallied this week.
"We know that Australia will also be a wounded team coming here after what happened against England at Twickenham.
"I think I will always have that little bit of fire bubbling away whenever I play against the Wallabies.
