  The inclusive jet cross-section is measured in proton-proton collisions at a
centre-of-mass energy of 7 TeV using a data set corresponding to an integrated
luminosity of 4.5 fb$^{-1}$ collected with the ATLAS detector at the Large
Hadron Collider in 2011. Jets are identified using the anti-$k_t$ algorithm
with radius parameter values of 0.4 and 0.6. The double-differential
cross-sections are presented as a function of the jet transverse momentum and
the jet rapidity, covering jet transverse momenta from 100 GeV to 2 TeV.
Next-to-leading-order QCD calculations corrected for non-perturbative effects
and electroweak effects, as well as Monte Carlo simulations with
next-to-leading-order matrix elements interfaced to parton showering, are
compared to the measured cross-sections. A quantitative comparison of the
measured cross-sections to the QCD calculations using several sets of parton
distribution functions is performed.
