This is an exciting time for the discovery of supernova remnants (SNRs) in galaxies other than our Milky Way. SNRs reflect a major process in the elemental enrichment of the interstellar medium (ISM). The study of this interaction in different domains including radio, optical, IR and X-ray, allow a better understanding of these remnants and their environments. Nearby external galaxies offer an ideal laboratory, since they are near enough to be resolved, yet located at relatively known distances.

I will review our most recent searches for SNRs in the Magellanic Clouds, M33, M31, NGC 300, NGC 45, NGC 6744 and NGC 7793. New high resolution (~1”) and sensitive (< 0.3 mJy beam-1) radio (ASKAP, ATCA & MWA), X-ray (XMM & CHANDRA), IR (Herschel and Spitzer) and optical (WIFES) images of these galaxies have preliminarily revealed thousands of sources from which we found a total of over 300 extended sources that are SNRs or candidates. We investigate their intrinsic and overall properties and found some remarkable and unexpected differences.

I will also present our breakthrough studies of first extragalactic SNRs expansion as well as our first detection of circular polarisation in extragalactic SNR. You will have a chance to see the most complete Sigma-D study of all KNOWN SNRs and how they interact with nearby molecular clouds. I will present the case for DD vs SD in Type Ia for some 15 LMC SNRs based on our X-ray and radio observations. Finally, I will present our strategies for the next 10 years on how to observe SNRs with the next generation of instruments — from ASKAP/MWA2 to CTA via eRosita and whoever else…
