We present a multi-wavelength study of the radio source G296.7-0.9 .
This source has a bilateral radio morphology , a radio spectral index of -0.5 \pm 0.1 , sparse patches of linear polarisation , and thermal X-rays with a bright arc near the radio boundary .
Considering these characteristics , we conclude that G296.7-0.9 is a supernova remnant ( SNR ) .
The age and morphology of the SNR in the context of its environment suggest that the source is co-located with an H ii region , and that portions of the shock front have broken out into a lower density medium .
We see no evidence for a neutron star or pulsar wind nebula associated with SNR G296.7-0.9 .
