We present results from a deep, coordinated $XMM$-$Newton$+$NuSTAR$
observation of the Seyfert 2 galaxy IRAS 00521-7054. The $NuSTAR$ data provide
the first detection of this source in high-energy X-rays ($E > 10$ keV), and
the broadband data show this to be a highly complex source which exhibits
relativistic reflection from the inner accretion disc, further reprocessing by
more distant material, neutral absorption, and evidence for ionised absorption
in an extreme, ultrafast outflow ($v_{rm{out}} sim 0.4c$). Based on lamppost
disc reflection models, we find evidence that the central supermassive black
hole is rapidly rotating ($a > 0.77$), consistent with previous estimates from
the profile of the relativistic iron line, and that the accretion disc is
viewed at a fairly high inclination ($i sim 59^{circ}$). Based on extensive
simulations, we find the ultrafast outflow is detected at $sim$4$sigma$
significance (or greater). We also estimate that the extreme outflow should be
sufficient to power galaxy-scale feedback, and may even dominate the energetics
of the total output from the system.
