Former Home and Away actor Martin Lynes has indicated he will fight additional charges related to an aggravated sexual assault for which he'll be sentenced next year.

Lynes, 50, was found guilty by a jury in August of digital penetration occasioning actual bodily harm on a woman at Bateau Bay on the NSW Central Coast in late-February 2016.

He will be sentenced in mid-March by Judge Robert Sutherland, who will also determine between four and eight related assault offences the Crown alleges occurred earlier the same day.

Lynes' lawyer, Pat Costa, told the Parramatta District Court on Thursday his client intends to plead not guilty to the additional charges.
