We present the discovery of a luminous unresolved HII complex on the edge of dwarf galaxy GAMA J141103.98-003242.3 using data from the Sydney-AAO Multi-object Integral field spectrograph (SAMI) Galaxy Survey. This dwarf galaxy is situated at a distance of ∼ 100 Mpc and contains an unresolved region of HII emission that contributes ∼ 70 percent of the galaxy's Hα luminosity, located at the top end of established HII region luminosity functions. For the HII complex, we measure a star formation rate of 0.147±0.041 M_☉/yrand a metallicity of 12+log(O/H) = 8.01±0.05 that is lower than the rest of the galaxy by ∼ 0.2 dex. Data from the HI Parkes All-Sky Survey (HIPASS) indicate the likely presence of neutral hydrogen in the galaxy to potentially fuel ongoing and future star-forming events. We discuss various triggering mechanisms for the intense star formation activity of this HII complex, where the kinematics of the ionized gas are well described by a rotating disc and do not show any features indicative of interactions. We show that SAMI is an ideal instrument to identify similar systems to GAMA J141103.98-003242.3, and the SAMI Galaxy Survey is likely to find many more of these systems to aid in the understanding of their formation and evolution.
