We show that each local field  $\mathbb{F}_q(\!(t)\!)$ of characteristic
$\mathbb{F}_q(\!(t)\!)$ of characteristic  $p > 0$ is characterised up to isomorphism within the class of all fields of imperfect exponent at most 1 by (certain small quotients of) its absolute Galois group together with natural axioms concerning the p-torsion of its Brauer group. This complements previous work by Efrat and Fesenko, who analysed fields whose absolute Galois group is isomorphic to that of a local field of characteristic p.
