Australia finished with the overall honours after day one of the third Test match of the series, but it could have been so much better for the tourists.
Facing a must-win game to hang onto the Ashes, England were on the threshold of cutting down the Australian line-up for a score under 200.
At 143-5, England only needed one more wicket to really press home their advantage, and perhaps, put their foot in the door, thus keeping the series and the dreams of retaining the Ashes alive.
But as they have done often so far this summer, the Australian lower order of Brad Haddin, Mitchell Johnson and to a lesser extent Michael Clarke, and the home side dug themselves out of trouble.
The WACA pitch showed signs of being bast and bouncy, but the lack of movement in the air or off the deck when combined with the varied length of the English bowling, allowed the Australians to mount their fightback.
Several loose strokes by Australia players led to their own downfall, with Shane Watson and George Bailey again failing.
But the big talking point from the day was the return to form of Steve Smith, who showed the fighting form that has been lacking so far from the English.
Smith looked in control for much of his innings and made it through to the end of the day’s play unbeaten on 103, with Johnson there with him on 39.
England need at least two wickets in the first hour of play on day two if they are to have a chance of restricting Australia to a total under 400.
And with the best days to bat at the WACA traditionally being the second and third, if the Australia tail continues to wag, as it has shown to do almost every innings this summer, then the English side will all but have lost the Ashes.
