We present results from an international spectroscopic and photometric campaign on the δ Scuti star AV Cet. The star has a rich and complex pulsation spectrum, and we find 7 individual frequencies, with evidence for many more present below our detection limit. We investigate the prospects for mode identification in fast rotators, using several different techniques. We compare the methods and conclude that although no single technique can give unambiguous mode identification, the collective evidence does allow some conclusions to be drawn, suggesting the presence of one radial mode at 14.598d^–1. During the campaign we found the star HD 9139 to be a variable. From our photometry we find evidence for a variability time scale around 1 day, but we cannot find an unambiguous interpretation for its light variations.
