Jordan strikes for England
Debutant Chris Jordan took his first international wicket, and Ben Stokes added two more in two balls, as Australia reached 81 for three after 15 overs of the NatWest Series decider at the Ageas Bowl.
The tourists progressed to 48 in 9.3 overs, for the loss of only Phil Hughes to Jordan, before play was interrupted by a shower for half an hour.
But on their return, Eoin Morgan's introduction of Stokes immediately compromised Australia.
On a quick pitch, first impressions were that a total approaching 300 would be par - and Australia could therefore not afford to be too conservative, even allowing for the loss of those three early wickets.
Barbados-born Jordan, called in by England to take the new ball in the absence of the injured Steven Finn, saw his first and fourth deliveries dispatched for four past cover by Aaron Finch.
He made short work of Hughes, though.
The left-hander has been out of the reckoning since the second Ashes Test, and was back only because of Shaun Marsh's hamstring problem.
He did not last long, tucked up by extra bounce as he shaped to pull and succeeding only in lobbing a simple catch into the leg-side ring.
Finch, on the ground where he smashed a Twenty20 world-record 156 last month, was undeterred as he and number three Shane Watson tried to set the tone in the powerplay overs.
The break for rain did them no favours, however.
Finch smeared a catch straight to Morgan at point from the first ball after the resumption, and Matthew Wade then made a golden duck when he gloved an attempted pull behind.
Michael Clarke, cleared to play after all despite another scare with his chronic back injury, therefore joined Watson as Australia set out to rebuild without conceding too much impetus.
