The Ryerson Index is information from Death & Funeral notices and obituaries in over 300 Australian newspapers and has entries from as recently as last Friday.
Put in the surname and the earliest year you know they were still alive.
If it's a popular surname then I suggest you search for each person by individual search,
e.g. SMITH David and SMITH Ann; but if it's an uncommon surname I'd only put the surname in.
Up to you. You might be lucky - or unlucky, depending on your point of view

If you find any of them, you might be able to get a snip of the actual notice. Finding a Published Notice (see LHS menu, front screen) tells you where you can look for a notice.
Good luck!
