Abstract
We present the results of new Australia Telescope Compact Array (ATCA) observations of one of the largest supernova remnants, SNR J0450-709, in the Local Group of galaxies. We found that this Large Magellanic Cloud (LMC) object exhibits a typical morphology of an old supernova remnant (SNR) with diameter $D = 102 x 75 pm 1$ pc and radio spectral index $alpha = -0.43 pm 0.06$. Regions of high polarisation were detected with peak value of $sim$40 per cent.
