AFL Sydney is in the final stages of confirming the fixtures across all divisions for the 2013 season.
AFL Sydney Football Operations Manager, Matthew Graham noted the Macarthur GIANTS announcement required an alteration to the Under 18 fixture.
"The inclusion of the Macarthur GIANTS into the Under 18 Division One competition is a positive for AFL Sydney but at the same time will mean the fixture will have to be re-done," he said.
Graham said the fixtures of the remaining divisions were on target to be released prior to the Australia Day weekend.
"The fixtures are with the AFL Sydney clubs who are now putting in their preferred times and locations for their home matches," he said.
"As per previous seasons, we aim to confirm the fixtures before the end of January."
