Transformers questions by newbies, and not-so-newbies

I don't think postage factors into the customs sums. Just what's on the declaration form.

It's only counted if you exceed $1000 of goods value, then they'll slug you customs duty and GST on it.

Running some numbers quickly, assuming you only bought complete 8 figure Generations cases:

9 cases: $950 goods value, $212 shipping

Total cost $1156

45 cases: $4725 goods value, $920 shipping, $282 customs fee, $593 GST

Total cost $6520

The equivalent total cost for 5 shipments of 9 cases is $5780, so you save nearly $750 by splitting shipments.

Shipping costs will be dependent on what you order and how efficiently it can be packed, but once you get to that level it scales almost linearly so it's unlikely to make a huge difference either way.
