Wind gusts that you would typically see in a category two tropical cyclone have blasted south-western Australia overnight, toppling trees and cutting power to more than 20,000 homes.
A powerful cold front linked to a deep and complex low pressure system caused squally winds across southwestern districts of Western Australia from Monday afternoon into Tuesday morning.
Another day of severe weather is forecast for WA today with warnings also in place for NSW, Victoria, the ACT and South Australia as similar condition blast the south east.
Western Australia

Intense showers with locally heavy falls will also develop over the western coastal districts and parts of the Great Southern.
The heaviest falls are likely to occur along the coast and adjacent inland between about Perth and Bunbury, where falls of 40-60mm are possible along the Darling Range.
This rain is expected to cause flooding in several rivers, including the Avon, Swan, Murray and Harvey Rivers Catchments.
In addition to wind and rain, this powerful front will also cause abnormally high tides and damaging surf along most of the state's western and southern coastlines.
This may cause beach erosion and flooding in some low-lying coastal areas.
There will be some respite midweek, before another strong cold front hits the state on Thursday.
