Looks like a good deal on a good sized dutch oven set. Last time it was posted on OzBargain it was $71.99, so enjoy it at $39.19 delivered (with prime).
While I haven't used this item, I've used their 25cm cast iron skillet (below) and it's good after a re-season. I always recommend re-season any cast iron cookware you buy.
The 25cm skillet is currently $25.17 https://www.amazon.com.au/Fresh-Australian-Kitchen-Pre-Seaso…
The 32cm skillet is currently $32.99 https://www.amazon.com.au/Fresh-Australian-Kitchen-Pre-Seaso…
2 IN 1 VERSATILITY: Use the 5.2 litre pan and 25 inch skillet separately, or use the frying pan as a lid to create a 5 quart double dutch oven dish. Sear, fry, bake, grill, broil, braise and sauté anything indoors and outdoors - on barbecues, induction and stove tops.
