I can't help except to suggest that the surname may start with a T or F.

Even more difficult when you are looking at unfamiliar 'foreign' names.
Perhaps a better scan or a better copy would make the words clearer, or maybe the ink used was just blotchy ...
Looking at this from a different angle may help ....
Did your ancestor's parents also go to Australia and live or die there?
Did any of your ancestor's siblings go to Australia? Parent's names on their marriage certificates may be clearer.
Do you have your ancestor's death certificate? Sometimes parents are unknown but may be worth looking at in case.
