Ewing was involved in an alleged fight with his ex-wife Marni Little's husband David Robertshaw.
On November 13, the actor was set to face Manly Local court on two counts.
But his manager Anthony Kidd has said the charges have been dropped.
Speaking to 9Honey he said, " the order and all surrounding allegations brought against him by ex-wife Little" were today dropped by police.
Police have stated that the AVO from Robertshaw is still in place..
Kidd said in a statement, "no charges will be laid by police for the alleged assault".
The AVO was placed after Ewing allegedly assaulted Robertshaw on October 21, during the custody exchange of Little's child with the actor - Archer.
According to a friend, Kate Fox, the authorities were called after Ewing "refused to give up custody of his son."
It has been reported the dispute went on for an hour.
Archer returned home with his mother.
The former couple ended their romance in December 2015.
