I will report on updated radio imaging observations of the Supernova 1987A (SN 1987A) remnant at 9 GHz, taken with the Australia Telescope Compact Array (ATCA), covering a 25-year period (1992-2017), which we use to probe the interaction of the SN shockwave with the complex circumstellar environment of the progenitor star.  From this work, we have found an increase in flux brightness in the remnant, and a change in the remnant expansion at Day ~9,300 from 2,300 to 3,610 km/s using a torus model fit for the radio emission.  I will show how our research has shown an increase in brightness in the western lobe of the remnant, although the eastern lobe is still the dominant source of emission, unlike what has been observed at optical and X-ray wavelengths.  Further, we have also seen the south-eastern side of the remnant is now beginning to fade, leading us to conclude the shockwave is now leaving the equatorial ring and re-accelerating as it does so.  I will also discuss the presence of high-latitude emission in SN 1987A in our data, which has been present from the earliest stages of the shockwave interacting with the equatorial ring.
