We present the discovery of a luminous unresolved H II complex on the edge ofdwarf galaxy GAMA J141103.98-003242.3 using data from the Sydney-AAOMulti-object Integral field spectrograph (SAMI) Galaxy Survey. This dwarfgalaxy is situated at a distance of ~100 Mpc and contains an unresolved regionof H II emission that contributes ~70 per cent of the galaxy's H_alphaluminosity, located at the top end of established H II region luminosityfunctions. For the H II complex, we measure a star-formation rate of0.147\pm0.041 M_solar yr^-1 and a metallicity of 12+log(O/H) = 8.01\pm0.05 thatis lower than the rest of the galaxy by ~0.2 dex. Data from the H I ParkesAll-Sky Survey (HIPASS) indicate the likely presence of neutral hydrogen in thegalaxy to potentially fuel ongoing and future star-forming events. We discussvarious triggering mechanisms for the intense star-formation activity of this HII complex, where the kinematics of the ionised gas are well described by arotating disc and do not show any features indicative of interactions. We showthat SAMI is an ideal instrument to identify similar systems to GAMAJ141103.98-003242.3, and the SAMI Galaxy Survey is likely to find many more ofthese systems to aid in the understanding of their formation and evolution.
