It comes as ex-Tropical Cyclone Gabrielle was downgraded to a deep low to strike the North Island of New Zealand overnight.

Already flooded Auckland residents have been told to expect more than 200mm of rain there today.

Back in Australia a tropical low is developing near Groote Eylandt in the Gulf.
The low is forecast to develop further near the western Gulf of Carpentaria coast during today and Tuesday and remain slow moving.
"The most likely scenario for the tropical low is for it to remain below cyclone strength, with gales to the south from later today," the bureau forecast..
"However, depending on how long the system is over the Gulf of Carpentaria waters, it may develop into a tropical cyclone as early as Tuesday morning, most likely reaching Category 1 system.

"From Wednesday, the system may start to track southwards and could cross the southern coast of the Gulf of Carpentaria, and weakening over land on Thursday."
Gales could extend to the NT/Qld border tomorrow.
Severe thunderstorms are also possible today.
NT emergency services have already issued warnings for residents to make preparations for a cyclone.
