The '''Australian High''', also known as the '''Great Australian Bight High''' or '''Southern Australian High''', is a large semi-permanent [[high pressure system|high pressure]] area or subtropical [[anticyclone]] that stretches from the [[Great Australian Bight]] in [[Western Australia]] and [[South Australia]] to the southern [[Victoria (state)|Victorian]] coastline on [[Bass Strait]] and the east coast of [[Tasmania]], between 30 and 40 degrees of south latitude.<ref>[https://earthobservatory.nasa.gov/images/78208/an-australian-anti-storm#:~:text=The%20weather%20system%20over%20the,high%20pressure%20near%20the%20surface.

In summer, it typically sits over [[southern Australia]] on the Bight, right below the coastline, where it generally provides dry weather in the proximate region. In winter it normally moves north, therefore permitting [[cold front]]s and [[low pressure system]]s to relocate up from the Great Australian Bight and bring rainfall to most parts of southern Australia. Whilst it primarily occurs and remains more stationerystationary in the warm season (Nov-Apr), it can intermittently make an appearance over the Bight in the cool season as well.<ref name = BOM>[http://www.bom.gov.au/climate/updates/articles/a025.shtml#:~:text=The%20subtropical%20ridge%20is%20a,on%20the%20climate%20of%20Australia.
