Just back with my Lady, from the grocery store, for our weekly foraging expedition.
Low and behold, right there on the self were packages of TimTam's, so I bought some.
Monstrously expensive at $5.49 per pack of either 5.3oz (150g) or 6.2oz (175g) containing 7 & 9 (cookies, bars, biscuits, other ... your choice) in two different flavors (flavours) of either "Original" or "Chewy Caramel". That prices out to well over a half dollar, nearly approaching a full dollar, apiece! The Originals were the smaller package, and I have to suspect that they were not quite "truly" original as they were clearly marked "Gluten Free", so there is that issue to contend with. Meanwhile, of these two available flavors the Originals did not have the word cookie anywhere on the package, but the Chewy Caramel did!?!? They both had the phrase "Irresistible Chocolatey Happiness in a Biscuit" on the wrapper, so I would presume that Jim, and likely other Aussie's would prefer us referring to them as BISCUITS!
I'll rate them as pretty darn good, and somewhat similar to, but not quite up to the standards of the term "Candy Bar", thus cookie seems closer to right on this side of the Big Waters!!!
Out of respect for Jim .... I'll always refer to them, henceforth, as Biscuits!
