    Certainly looks similar to the Atlas Centaur pieces shown on Paul Maley's web
    site (see Atlas Rockets):
    To make an ID with certainty, we need to know the date it fell, or the earliest
    and latest possible date. The following article is helpful in that regard:
    "James Stirton found the 54cm wide, 20kg, burnt-up ball on his 40,500-hectare
    property in Cheepie, west of Charleville in the state's south-west in November."
    According to this article, it may have been spotted within a week of its fall:
    "It was just off the road and I had been going up there every couple of days to
    feed cattle so I would be surprised if it had been there more than a week," Mr
    Stirton said.
    And this:
    "... aerospace industry sources who contacted Mr Stirton believe it to be part
    of a rocket launched at Cape Canaveral, Florida, in 1998"
    A single Atlas Centaur launched from Cape Canaveral decayed in 2007: 98016B /
    25259, on 2007 Oct 24 UTC. Decay date is in reasonable agreement with the above
    Propagating 98016B's latest elements with Satevo 0.51, and then computing its
    ground track and altitude, I find some possibility that it could have begun its
    terminal descent on 2007 Oct 23, about 23:47 UTC. According to Heavens-Above,
    Cheepie is at 26.633 S, 145.017 E, which is very close to the terminal track;
    decay would have been sometime around 00:09 UTC, on Oct 24.
