Having conquered the season of summer, Football Federation Australia (FFA) has expanded its borders well into autumn in the battle with winter codes AFL and NRL.

The 2013/14 A-League season will start on October 11 and run until May 4 - its latest finish in nine years.

Allianz Stadium, home of Sydney FC and a slew of NRL teams, will host A-League matches in four of the final six rounds before finals start.

That run begins with the Sky Blues' derby match against Western Sydney on March 8, a match that could well coincide with round one of the NRL.

Anzac Day has been the sporting domain of AFL power clubs Essendon and Collingwood, and NRL rivals Sydney Roosters and St George Illawarra for some time.
