"If you come on a wicket that's got some grass and Josh Hazlewood, [Pat] Cummins and [Mitchell] Starc are rolling in at you. Is it going to be the same? We'll see what happens."
Pat Cummins' side are 1-0 up in the series against Sri Lanka after batting at more than 4.5 runs an over in last week's first test, which was over in two days and one session.
England's energised approach to test cricket borrows heavily from Australia - the constant positivity, running hard between the wickets and attacking fields. Where they differ is that Australia have genuine pace.
"I think you saw the last test against England, the pink ball game in Hobart, when 'Heady' [Travis Head] and Marnus [Labuschagne] started to take the game on, the wicket was doing plenty, so it was a counteract, put the pressure back on the bowler mentality, and it worked on that occasion. Is it going to work every time? I don't know," said Smith.
"Guys just keep joking about it – I think Ronnie [Andrew McDonald, Australia head coach] has had enough of hearing about Bazball to be honest, it's good fun to joke about."
