Hells Gates (Tasmania)
- Hells Gates is also the name of a gorge on the Davey River in the south west region of Tasmania.
It is a notoriously shallow and dangerous channel entrance to the harbour. The actual channel is between Macquarie Heads on the west and Entrance Island on the east (the main length of the harbour runs southeast of Hells Gates). There is a wider area of water between Entrance Island and Macquarie Head, but it is too shallow to get a boat over.
Braddon Point is the name of the feature on the eastern shore, while the shallow water south of the point is named Fraser Flats, and the channel adjacent to the breakwater is known as Kelly Channel.
The name of the channel relates to the original convicts' claim that it was their point of 'entrance to Hell', their Hell being the Macquarie Harbour Penal Station on Sarah Island and the outlying surrounds of the harbour.
Breakwater and channel
Between 1900 and 1902 the Macquarie Harbour Entrance Works  involved the building of a breakwater and the channel was dredged. Parts of the breakwater can still be seen despite the passage of time. The Strahan Marine Board  was involved with the monitoring of the mouth until 19 May 1970, when the Hobart Marine Board took over.
Both Entrance and Bonnet Islands have lights, and they were built before the Cape Sorell lighthouse.
Charts and maps
Due to the precarious entrance, and the changes in the hydrology of the area, charts and maps were updated regularly while Strahan was a port of importance - some of these maps are now available online, for example 
- Geoscience Australia (http://www.ga.gov.au/place-name/ ) has three other locations in Tasmania using the same name - the Macquarie harbour entrance is the only official usage:

- Hells Gates Unofficial Lat -41 37 Long 145 3
