Three wide-margin wins over England have put the hosts in an unassailable lead already, with a whitewash on the agenda if they can close the deal again in the Boxing Day Test in Melbourne and then Sydney in the new year.
But Clarke is mindful that the sudden rush of success is at odds with what preceded it, under his captaincy -- including Australia’s own 3-0 Ashes defeat in England last summer.
He is therefore both mildly empathetic with the lot of his opposite number Alastair Cook, and very wary of crowing about Australia’s improvement just yet.
“We’ve experienced a lot of tough times over the past couple of years -- especially the last 12 months, when we haven’t had much success at all,” he said.
“So I don’t think it would be fair for me to sit here and give advice to Alastair or the England team -- because we’ve only won three Test matches out of a dozen now.
“That certainly doesn’t sound like a successful Test cricketing year for an Australian team. “We’re ranked fifth in the world and won three Test matches in the past 12 months, so there’s no complacency at all.
“This Test is as important as (the first one in) Brisbane was.” Clarke has had a prolific series so far at number four, but added: “I know how quickly you can be praised by the media and I also know how quickly you can be criticised.
“I’m not silly enough at 32 years of age to look past tomorrow - because I know a couple of ducks and my job’s on the line, or a couple of losses and I’m under the same pressure.”
As for Cook, the advice from down under is that -- however bad things seem -- the tide will turn eventually. “You’ve just got to keep the faith,” Clarke said.
“England have a very good team, a lot of very good individual players.”
