Batsmen tied down
Ricky Ponting won the toss and after chosing to bat first, quipped that he may as well have agreed it with England captain Andrew Strauss beforehand given Strauss's preference to bat second.
Ponting's call looked a shaky decision early on as England tied down the Aussie batsmen. Stuart Broad, James Anderson and Tim Bresnan kept things tight and the visitors looked troubled.
Broad got rid of Shane Watson and Ponting early on - both succumbing to the bouncer trying to play shots.
Wicket-keeping opener Tim Paine dug in, working his way to a half-century aided by Cameron White and then Shaun Marsh.
Marsh came in later in the innings and, after taking time to settle in, start to play some expansive strokes.
After Paine went, Mike Hussey and Marsh guided Australia from a troubled looking total past 200 and beyond.
As both sailed past their own half-century mark the Australia total suddenly started to look ominiously large.
Graeme Swann had done his first over magic again removing Paine - then later taking the wickets of White and Marsh too.
Steve Smith and James Hopes added a few useful runs from the tail - Smith especially swinging the bat. 277-7 from their 50 overs looked a more than par score, especially after a slow start.
Another slow start
England started in a similar vein to Australia Strauss and Kieswetter looking more than a little startled by Tait express pace.
Facing Tait, who was only added to the Australia side midway through the tour (after the defeat in Cardiff), looked a terrifying prospect. He was clocked at 100mph in his first over - the first 100mph delivery on English soil.
Tait surprised everyone lasting beyond a short burst and in his 3rd over he more than surprised Strauss, exploding a delivery past the a gob-smacked skipper shattering his stumps.
With usual number three, Kevin Pietersen crocked by a thigh muscle tear sustained in the field, England called on Michael Yardy to bat in his position.
The unfortunate Yardy lasted just two balls of Tait's turbo-charged pace before he too found his stumps in a mess.
Harris and Bollinger were bowling quick stuff aswell and Kieswetter followed Strauss and Yardy back to the Pavilion in the 8th over.
Man of the Series, Eoin Morgan, came out to bat and once again England needed a saviour - even moreso with Pietersen hurt.
Morgan could score only nine runs and injured or not Pietersen was needed.
Kieswetter escorted him to the crease ready to act as his runner. With Paul Collingwood looking his usual rock-solid self, England needed Pietersen to settle.
He didn't and soon Kieswetter was walking back to the Pavilion for a second time, along with Pietersen after the latter chopped a ball from Steve Smith onto his own stumps.
At 73-5 England looked in serious trouble, facing the prospect of a thrashing.
Luke Wright did the Collingwood-accompanying job and the two scored a 50 partnership to settle England's frayed nerves.
Once again Australia had that something special though - Shaun Marsh, who'd done so much damage with the bat, took a running, diving, juggling catch to not only prevent an almost certain boundary but remove Wright.
Tim Bresnan came in and he too batted with creditable calm, adding another 50 partnership with Collingwood.
As England neared 200 Ponting looked a little concerned.
He called upon Tait to return to the attack and the change was enough to unsettle England.
Bresnan binked the ball to his right and set off for a scrambled single. Ponting himself picked it up in a flash and threw down the stumps a fraction before Bresnan got there. The captain's quicksilver fielding probably clinched the game in that moment.
Collingwood followed shortly afterwards, having scored an impressive 95, another victim of a snorting delivery from Tait sending stumps tumbling.
Graeme Swann performed his almost customary cameo - switch hitting and galloping down the wicket to plunder boundaries. The crowd cheered but there was a tinge of irony - they knew it couldn't last.
It didn't. Stuart Broad fell first, though he can count himself unlucky. As Broad drilled one back past Bollinger, the bowler stuck out a hand, almost in self defence. The ball stuck and Broad had to go.
Swann went in the next over a fourth wicket for the deserving Tait, as Swann holed out to Ryan Harris near the boundary.
England celebrated on the podium. They'd won the NatWest Series long before the teams arrived at Lord's. Victories in the first three matches of the five match series meant this was, officially academic.
However, despite their slow start in the series Australia look a changed side from that beaten so convincingly in the early matches.
A large part of that change has come in the confidence imbued by Tait frighteningly quick bowling.
In their post-match interviews man-of-the-match Tait and Ponting were talking about the former's Ashes prospects. On this form England may be hoping he turns down the opportunity.
