Grapevine fanleaf virus (GFLV) was previously recorded in South Australia and Victoria (Taylor 1962; Taylor and Hewitt 1964; Meagher et al. 1976; Cirami et al. 1988). There are three unconfirmed records of GFLV in New South Wales from 1927, 1972, 1989 on the Australian Plant Pest Database (PHA 2001) identified by symptoms. There are no other reports of this virus in New South Wales. Up to 2001, Waite Diagnostics had sampled over 5000 assays of grapevine from New South Wales, Victoria, South Australia and Western Australia and only four of the samples tested positive for GFLV (two from South Australia, two from Victoria) (Habili et al. 2001). In South Australia, GFLV affected grapevines were found in the absence of their known vector Xiphinema index (Cirami et al. 1988; Habili et al. 2001). The two grapevines that tested positive for GFLV in South Australia (2001 and prior) were destroyed. The known vector, X. index, is absent from South Australia. Since 1997, under the testing of the Australian Vine Industry Improvement Association, 2,000 samples per year are tested for GFLV in South Australia without detection. In Victoria, GFLV and its vector occurred only in the Rutherglen district and quarantine restrictions prevented their movement to other regions (Krake et al. 1999; Habili et al. 2001). There have been no official reports of GFLV in Victoria (Rutherglen) since the 1960s and it is thought that GFLV is no longer present in the area due to the removal of infected plants. In recent years, there have been no reports of fanleaf disease in South Australia or Victoria (Constable et al. 2010), despite routine surveillance, domestic testing and post-entry quarantine pathogen screening. Therefore, GFLV is considered absent from Australia.
