Bushfire smoke?

Today started out bright and sunny, but there's been a haze creeping across the sky, and the sunlight's become quite dim. The light's also gone a funny colour.

This is sunlight shining in my window onto a sheet of white printer-paper. It shouldn't be that peach colour. It's more than 5 hours before sunset.

Is this smoke from the fires in Victoria, Australia? I remember in the Summer of 2001/2002 we had a noticeable smoke haze from bushfires around Sydney.
