Mitchell Johnson undergoes video analysis in Adelaide in a bid to fix his wayward bowling action

Out-of-sync Johnson was axed from the second Test side against the wishes of skipper Ricky Ponting. But the left-armer remained with Australia's squad to work with bowling mentor Troy Cooley instead of finding form with Sheffield Shield side Western Australia.

Johnson yesterday returned to the nets in a 45-minute session complete with ball-by-ball video camera analysis under the eye of Cooley, batting coach Justin Langer, strength and conditioning guru Stuart Karppinen and fellow discard Ben Hilfenhaus.

Every step of enigmatic Johnson's sling action was broken down to isolate the glitches that have scrambled his radar and restricted the one-time truck driver to 11 wickets in five Tests.

"It is a tough one, management probably knows better in this case.

"Yes, on one side of the coin you do need to do some remedial work, while match practice is an important element. I don't have a problem with him remaining with the side."

The pressure is increasing on Australia's coaching staff to fix Johnson - and quickly.

Crucially, Johnson appeared to be getting his arm action high again following a long talk with swing man Hilfenhaus - knowing that is the gateway to regaining the inswinger that is vital to his bowling arsenal.

Fallen spearhead Mitchell Johnson has started his quest for Ashes redemption and a third-Test recall in Perth by refitting his blown-out action in Adelaide's practice nets.

Ferguson, George to have Ashes headstart

In the race to a make the Australian team for the Ashes, Callum Ferguson and Peter George have a two-match start on the rest of the field.

They will be pitted against England in a tour match at Adelaide from November 11-13 and will then likely back-up for Australia A against the tourists at Hobart from November 17-20.

No other Redbacks are considered close to the Test side.

"It would be nice to be involved in both of those games," Ferguson told AAP.

"It has just been great to be around the boys again, it's been a long time, and I managed to get a few hits in over here in the nets and whatnot on Indian wickets which was good.

"All is not lost, I've been able to get in the gym with Stuart Karppinen our strength and conditioning coach as well."

"Definitely I'm fitter, I had to be I guess, I need to get my knee to a point where it is stronger than it was and we're pretty close to that at the moment," he said.

"My right leg is matching my left leg which is good, if not probably a little bit more stable, so it's in a good place and my fitness in general is probably at a higher level than it was when I got injured."
