Note that the A$9169 for DGLOB34 Business Class Global Explorer fare is exactly the same as the DONE4 OneWorld Explorer 4-continent fare.

On a OneWorld Explorer ticket, you have to go Round The World. For this ticket, the world is split into 3 areas, with 2 continents in each area. You must travel in a continuous direction between the three areas. Also note that there is no OneWorld airline that flies between South America and Africa, so you cannot do a 3-continent OWE in the soouthern hemisphere as you can in the northern hemisphere. So the minimum OWE that includes any southern hemisphere continents (South America, Africa, or SW Pacific) is 4-continents.

The term "affiliates" in OneWorld refers to subsidiaries of the main OneWorld alliance partners. The OneWorld Affiliates are listed here. They include airlines like American Eagle as an affiliate of American Airlines, and QantasLink as an Affiliate of Qantas. Each airline may also have its own partnerships and sometimes part ownership (such as QF and FJ), but that does not make the partner airline a OneWorld Affiliate.
