We have conducted a widefield, wideband, snapshot survey using the Australian SKA Pathfinder (ASKAP) referred to as the Rapid ASKAP Continuum Survey (RACS). RACS covers ~90% of the sky, with multiple observing epochs in three frequency bands sampling the ASKAP frequency range of 700-1800MHz. This work contains the catalogues from the third major epoch at 1655.5MHz, RACS-high. From the 1493 images covering the sky up to declination +48 degrees, we present a catalogue of 2677509 radio sources and 3526674 Gaussian components. The catalogue is constructed from images with a median root-mean-square noise of 195uJy/beam and a median angular resolution of 11.8" by 8.1". The overall reliability of the catalogue is estimated to be 99.18%, and we find a decrease in reliability as angular resolution improves. We estimate the brightness scale to be accurate to 10%, and the astrometric accuracy to be within ~0.6" in right ascension and ~0.7" in declination after correction of a systematic declination-dependent offset. All data products from RACS-high, including calibrated visibility datasets, images from individual observations, full- sensitivity mosaics, and the all-sky catalogue are available at the CSIRO ASKAP Science Data Archive: https://doi.org/10.25919/g3jd-av02.
