Australian musician Megan Washington will perform before the AFL Women's Grand Final on Saturday at Metricon Stadium.

Washington will sing the national anthem as well as some of her own songs, and the songwriter will also perform at the AFLW Awards night in Melbourne next Tuesday night.

The singer said she was "excited and honoured" to be involved in the AFLW grand final.

"It's an historic day for the Australian sporting community…it's been inspiring to witness such a high level of community support for the women's competition," she said.
