We report on high‐resolution observations (R=35 000) of the Hubble Deep Field South QSO J2233‐606 obtained with the University College London Echelle Spectrograph at the Anglo‐Australian Telescope. We present spectral data for the wavelength region 3530 < λ <4390 Å. The data have a mean signal‐to‐noise ratio in the continuum of approximately 15 per 0.05‐Å resolution element at λ > 3700 Å. Voigt profiles are fitted to determine the redshift and column densities of the observed features. Eight heavy‐element intervening systems are identified, as well as an associated system showing evidence for incomplete coverage of the background source.
