So William B. Algeo was the one who came out to Australia... does anyone have any further info on him? Also for Robert as well?
The information I posted earlier is from an online tree which may, or may not be reliable which is why you need to go back and check Australian records before searching in Ireland. If William Butterfield Algeo was the ancestor who came to Australia then if was before 1857.
See these two topics about researching Irish ancestors and Irish records- there are more online resources since they were written but the basic details are still applicable.

The information you provided helped gain some clarity in understanding the information I had discovered in recent research - the issue I've been having is organising such information into a cohesive timeline. I checked out the family tree you attached and looked up several sources (eg. Trove and state libraries), and it's starting to make sense now.
Said family tree also lines up (for the most part), with a well-researched, established family genealogy document in my family.
The genealogy document only went as far back as Charles, hence why I wasn't 100% sure who Charles' father or grandfather was at the time of my OP
