  The solar galactic neighbourhood contains a number of young co-moving
associations of stars (so-called `young moving groups') with ages of ~10--150
Myr, which are prime targets for a range of scientific studies, including
direct imaging planet searches. The late-type stellar population of such groups
still remain in their pre-main sequence phase, and are thus well suited for
purposes such as isochronal dating. Close binaries are particularly useful in
this regard, since they allow for a model-independent dynamical mass
determination. Here we present a dedicated effort to identify new close
binaries in nearby young moving groups, through high-resolution imaging with
the AstraLux Sur Lucky Imaging camera. We surveyed 181 targets, resulting in
the detection of 61 companions or candidates, of which 38 are new discoveries.
An interesting example of such a case is 2MASS J00302572-6236015 AB, which is a
high-probability member of the Tucana-Horologium moving group, and has an
estimated orbital period of less than 10 years. Among the previously known
objects is a serendipitous detection of the deuterium burning boundary
circumbinary companion 2MASS J01033563-5515561 (AB)b in the z'-band, thereby
extending the spectral coverage for this object down to near-visible
wavelengths.
