Australian rugby league hooker Danny Buderus says it's time to put the football heads on when the Kangaroos step up their European tour against England A in London.

After the squad spent last week bonding in Barcelona, Buderus says the tourists must get serious about the football.

Coach Chris Anderson has made seven changes to the team which beat the French Selection last week to take on a bright young English side and says the team will take a couple of games to gel.

The understrength Kangaroos face their biggest challenge in 30 years when the three Test series against Great Britain starts on November 8.

But their tour has begun poorly with a loss to New Zealand and an unimpressive 34-10 win against a French Selection in Carcassonne.
