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.
