Already facing 20 bestiality charges for allegedly possessing hundreds of videos of the offensive material, police will add another 29 counts in court on Monday to the man who goes by the online pseudonym 'Beast Boy'.
The 38-year-old man was arrested and charged in April after police found he had a large online presence and was using encrypted messaging apps to share bestiality, with some of the content allegedly depicting sexual abuse of a dead kangaroo.
The additional charges include seven counts of bestiality, five counts of possessing and sharing bestiality material, animal cruelty, child abuse material possession and 15 counts of using a carriage service to share child abuse material.
When he was arrested in April, a Jack Russell terrier cross also was found at his property in Moorland about 30km north of Taree on the NSW mid-north coast.
Police say the dog had been missing from the Grafton area for around five years and has since been returned to its owner.
Speaking in May, NSW Detective Superintendent Jane Doherty said the 38-year-old's online presence showed even more content than they were expecting.
"We have viewed in excess of 500 videos at this point and that is just on initial review," she said.
"What we have reviewed so far shows that it has been going on for a number of years - we don't have an exact date yet."
The extra charges were added after analysis of seized electronics and hard drives.
Police now say they've found thousands of videos and images of bestiality and child abuse material.
'Beast Boy' remains on remand.
