Using carbon-dioxide-baited light traps and larval sampling, anopheline mosquitoes were collected from 620 sites in northern Australia. Twelve species were recorded. Anopheles annulipes s. l. (335 sites). An. bancroftii (181 sites), An. meraukensis (162 sites), An. farauti s. s. (133 sites), An. farauti 3 (93 sites), An. amictus (93 sites), An. hilli (88 sites), An. novaguinensis (70 sites), and An. farauti 2 (67 sites) were common and widespread throughout the region, while An. powelli (5 sites), An. stigmaticus (2 sites), and An. colledgei (1 site) were rarely collected. At the time of the surveys the distribution of these species was not limited by the availability of oviposition sites.
