  This paper is part of a series describing the results from the Australia
Telescope Hubble Deep Field South (ATHDFS) survey obtained with the Australia
Telescope Compact Array (ATCA). This survey consists of observations at 1.4,
2.5, 5.2 and 8.7 GHz, all centred on the Hubble Deep Field South.
  Here we present the first results from the extended observing campaign at 1.4
GHz. A total of 466 sources have been catalogued to a local sensitivity of 5
sigma (11 microJy rms). A source extraction technique is developed which: 1)
successfully excludes spurious sources from the final source catalogues, and 2)
accounts for the non-uniform noise in our image. A source catalogue is
presented and the general properties of the 1.4 GHz image are discussed. We
also present source counts derived from our ATHDFS 1.4 GHz catalogue.
Particular attention is made to ensure the counts are corrected for survey
incompleteness and systematic effects. Our counts are consistent with other
surveys (e.g. ATESP, VIRMOS, and Phoenix Deep Field), and we find, in common
with these surveys, that the HDFN counts are systematically lower.
