A weak tropical low and trough in the Arafura Sea is causing lots of clouds in the Top End and Cape York Peninsula. There's a band of clouds moving across central NSW bringing rain and thunderstorms to NSW and southern QLD. A low pressure system off the coast of central NSW is also causing clouds and thunderstorms in the area. Onshore winds are creating clouds in southern WA, SA, and southwestern VIC, while an upper trough is causing clouds in central WA. The rest of the country is mostly clear of clouds.
