Former Auburn deputy mayor Salim Mehajer says "only death" will part him from his wife Aysha, after police applied for an Apprehended Violence Order on her behalf.

Mr Mehajer will face Sydney's Downing Centre Local Court on Wednesday when the AVO application, made under his wife's maiden name Aysha Amelia Learmonth, will be heard.

However, the property developer has denied his wife applied for the order against him, posting photographs of her on Facebook and accusing the police of "having nothing better to do".
