External doors should be solid not hollow core. Beyond that it is as Tribbletrouble44152k7 Trek said, depends on budget and other priorities, and I'll add the house because the nicest most expensive door will look wrong if it looks out of place with the style/colours of the house. From everything I have been told a timber finish needs redoing more often than a painted finish. Edited to add, I thought to check what exactly the standard Hume XS45 1200 door is and for clarification the question is about the same style but the choice between the standard maple finish and the merbau finish? I therefore assume you intend to use a timber finish and amend my reply to ask whether the merbau is a better match for the other colours in your facade?

We've ended up choosing Yokor Windows & Doors. They're a Chinese import company with very high quality product. A builder friend of mine recommend him who used them in his own house. We are yet to order though. They were about 8k cheaper than The other company we were tossing up between. The only issue i don't like their flyscreen product so we'll get that from someone else.

They look like steel doors but after a quick Google search nothing came up in Qld, only Melbourne and Sydney. I guess you'd already done this too hence your question. You could always order from interstate or maybe use aluminium instead. Maybe try a local heritage architect as they may have a local contact.
