MAXI J1535-571 is a Galactic black hole candidate X-ray binary that wasdiscovered going into outburst in 2017 September. In this paper, we presentcomprehensive radio monitoring of this system using the Australia TelescopeCompact Array (ATCA), as well as the MeerKAT radio observatory, showing theevolution of the radio jet during its outburst. Our radio observations show theearly rise and subsequent quenching of the compact jet as the outburstbrightened and then evolved towards the soft state. We constrain the compactjet quenching factor to be more than 3.5 orders of magnitude. We also detectedand tracked (for 303 days) a discrete, relativistically-moving jet knot thatwas launched from the system. From the motion of the apparently superluminalknot, we constrain the jet inclination (at the time of ejection) and speed to$\leq 45^{\circ}$ and $\geq0.69$c, respectively. Extrapolating its motion backin time, our results suggest that the jet knot was ejected close in time to thetransition from the hard intermediate state to soft intermediate state. Thelaunching event also occurred contemporaneously with a short increase in X-raycount rate, a rapid drop in the strength of the X-ray variability, and a changein the type-C quasi-periodic oscillation (QPO) frequency that occurs $>$2.5days before the first appearance of a possible type-B QPO.
