Using images from the GaLactic and Extragalactic All-sky Murchison Widefield Array (GLEAM; MWA) survey, I have discovered 27 new supernova remnants (SNRs) via their non-thermal emission at low radio frequencies. Some of these are quite unusual objects with very low surface brightness, while others were simply hidden from view due to confusion between thermal and non-thermal emission at higher radio frequencies. For six candidates I have suggested pulsar associations and can derive physical characteristics. I will conclude the talk with future prospects for further discoveries using upcoming MWA surveys.
