We present a search for prompt radio emission associated with theshort-duration gamma-ray burst (GRB) 150424A using the Murchison WidefieldArray (MWA) at frequencies from 80-133 MHz. Our observations span delays of 23s-30 min after the GRB, corresponding to dispersion measures of 100-7700pc/cm^3. We see no excess flux in images with timescales of 4 s, 2 min, or 30min, and set a 3 sigma flux density limit of 3.0 Jy at 132 MHz on the shortesttimescales: some of the most stringent limits to date on prompt radio emissionfrom any type of GRB. We use these limits to constrain a number of proposedmodels for coherent emission from short-duration GRBs, although we show thatour limits are not particularly constraining for fast radio bursts because ofreduced sensitivity for this pointing. Finally, we discuss the prospects forusing the MWA to search for prompt radio emission from gravitational wavetransients and find that while the flux density and luminosity limits arelikely to be very constraining, the latency of the gravitational wave alert maylimit the robustness of any conclusions.
