Having played against quite a few overseas players I think its just the Aussie way on the field
Most of the ones ive come across have been like this as that is the way they are raised to play the game we are raised to play it our way
We call them arrogant they call us wimps but we are more gentlemanly than they are
will say nearly all were different in the bar afterwards bit like Jekyll and hyde
Can't say I like it as more and more players starting to do it and it puts me off playing certain sides as I just don't need or want it at my age
