Ex-Tropical Cyclone Alfred is dumping heavy rain across large parts of South East Queensland and northern New South Wales as it moves inland after crossing the Queensland coast this morning.

Meteorologists say the tropical low is still packing a punch in parts of south-east Queensland and northern NSW ahead of the new working week.

Significant damage and power outages are possible in the densely populated region of Queensland, where tropical cyclones impacts are not uncommon but direct landfalls are.
