In which year did Cyclone Mahina strike the Eastern coast of Australia?

As of February, 2019, 'Cyclone Mahina' was the deadliest cyclone in recorded Australian history, and also likely the most intense tropical cyclone ever recorded in the Southern Hemisphere.

'Mahina' struck Bathurst Bay, Cape York Peninsula, Queensland, on the 4th of March 1899, and its winds and enormous storm surge combined to kill more than 300 people.

While the Australian Bureau of Meteorology, which is the Regional Specialized Meteorological Center of the basin, estimates 'Mahina's' peak central pressure to be 914 hPa [hectopascals] (26.99 inHg), the World Meteorological Organisation is currently considering an application from Queensland scientists and researchers to have this value upgraded to 880 hPa (25.99 inHg), based on data from post-storm analysis.

This would officially make 'Mahina' the most intense cyclone recorded to have hit the Australian mainland, and the most intense tropical cyclone ever recorded in the Southern Hemisphere, a title currently held by Cyclone Winston. Cyclone Mahina also produced the largest storm surge on record, generating a 13-metre (43-foot)-high surge

Storms of such intensity occur extremely rarely. Scientists identified two other Category-4 or 5 super-cyclones that struck Australia, in the first half of the 19th century, from their effects on the Great Barrier Reef and the Gulf of Carpentaria.

This same research shows that on average, such super-cyclones occur in the region only once every two or three centuries.
