I must admit that I did not know what shirtfronting meant when Mr Abbott used it in the context of Mr Putin. I am obliged to the ABC for this definition:
For the Shirtfront (Australian Rules) noun, "A fierce tackle, usually delivered by the shoulder to the chest of an opponent." verb, "The act of delivering such a tackle." - Oxford Australian Dictionary.
The ABC story linked above has some video clips of the now banned shirtfronting in practice. The Russian local diplomatic response can be found here. Mr Abbott has not repeated the term, referring instead to possible robust discussions. PUP Senator Jacqui Lambie takes a dim view of the whole thing, praising Mr Putin’s “great values”.
There is an air of unreality about the Australian discussion. This includes Opposition leader Shorten who wishes that the Government could have done more to prevent Mr Putin attending the Brisbane G20 summit. Yes, Australia’s political leaders need to reflect local concerns, but that also needs to be tempered with a degree of reality.
