  Recent measurements of top quark properties using $t{\bar t}$ events produced
in proton-proton collisions at the Large Hadron Collider with centre of mass
energies of 7 and 8 TeV and detected by the ATLAS experiment are presented.
These results include top quark mass, the top and anti-top mass difference, the
electric charge, the top quark polarization and spin correlation, the $t{\bar
t}$ charge asymmetry and the search for flavour changing neutral currents.
