British officials have boosted security for the second Ashes Test, as Australia's cricketers expressed concern for their safety, following the London bombings.

"There's obviously concern amongst the team about the situation in London but there's certainly not panic," Australian Cricketers Association (ACA) chief executive Paul Marsh told AAP.

"There's obviously the complication about most of the guys having their partners and their children with them.

"There's no plans for the players to jump on a plane and come home. We're reviewing security on a daily basis with Cricket Australia."

Warwickshire County Cricket Club (CCC) says the number of stewards at Birmingham's Edgbaston ground will be doubled to 500.

Full searches will be carried out on all fans arriving at the ground, in the wake of the July 7 bombings on London's transport network which killed more than 50 people, and the failed July 21 attacks in the city.

Warwickshire CCC chief executive Dennis Amiss says security sweeps have been put in place this week, including the use of extra security and police patrols, and sniffer dogs.

"The safety of the players, staff and spectators is our first priority," Amiss told the Press Association.

The new security measures came as Australian fast bowler Jason Gillespie said he would consider going home if there is another bomb attack in England.

"If another bomb did go off here in England, there would be serious questions asked, I think, about the tour because I know a lot of the guys are quite nervous," Gillespie has told Melbourne radio station 3AW.
