Already trailing in the NatWest One Day Series, Australia have been forced to make a change to their squad with spinner Nathan Hauritz sent home injured.
Off-spinner Hauritz has been suffering with a foot injury and with the condition worsening Cricket Australia have opted to send him home for treatment.
Called up in his place is pace bowler Shaun Tait.
Tait recently called time on his first-class career insisting the strain on his body was too much.
However, the talented seam bowler has been playing Twenty20 cricket for Glamorgan. Perhaps it was no coincidence he was in Cardiff to watch Australia go 2-0 down in the series.
Tait's explosive bowling style will add a new element to the Australia attack and Stuart Broad's 4-44 in Cardiff may have influenced the decision to add him to the squad.
Off-spinner Hauritz enjoyed a see-saw tour of England last year.
Criticised in the press even before a ball had been bowled Hauritz was seen as a weak link in the Australia side.
Hauritz took ten wickets in the Ashes Series, including six in the first match in Cardiff - a Test Australia arguably should have won.
However, on day one of the second Test at Lord's he dislocated his finger attempting to catch Andrew Strauss off his own bowling.
He bravely returned, taking three wickets in England's second innings, but England won that Test and the series - famously reclaiming the Ashes.
With Hauritz missing from the one day squad (and likely to miss the Tests against Pakistan) 21-year-old leg-spinner Steve Smith looks likely to shoulder more of the spin bowling burden.
