Brief description We propose to continue monitoring Southern relativistic binary pulsars
to place stringent limits on General Relativity, pulsar masses, and to
map the emission cone of PSR J1141--6545 at 20cm, which we have
established is undergoing rapid profile evolution. In light of
our recent results, we wish to propose more regular observations
of this pulsar. Our instrumentation is the most sensitive to the
evolution of complex features in the double pulsar's profile at
50cm wavelengths which we aim to monitor on an annual basis.
