  The southern supernova remnant (SNR)W28 was observed in 1994 and 1995 by the
CANGAROO 3.8m telescope in a search formulti-TeV gamma ray emission, using the
Cerenkov imaging technique. We obtained upper limits for a variety of
point-like and extended features within a +-1 degree-region and briefly discuss
these results, together with that of EGRET within the framework of a shock
acceleration model of the W28 SNR.
