  We report on the discovery of a new Small Magellanic Cloud (SMC) symbiotic
star, OGLE-SMC-LPV-00861, previously catalogued as H$\alpha$ emission line
source LIN 9. The OGLE light curve shows multiple-maxima outburst behaviour
over $\sim$1200 d with a maximum outburst of $\Delta V=1.5$ mag. An optical
spectrum of LIN 9 taken with the Southern African Large Telescope (SALT) at
quiescence reveals a K5 red giant with emission lines confirming its symbiotic
star nature, demonstrating the potential use of ongoing large time-domain
surveys to identify strong symbiotic star candidates. It is the first
Magellanic symbiotic star proven to show poorly understood Z And outbursts. At
outburst the estimated hot component luminosity is $L\sim3165$ $L_\odot$,
compared to $L\sim225$ $L_\odot$ at quiescence. Further observations are
needed, especially at outburst, to better understand this unique Z And-like
system at a known distance, and to provide essential input to physical models
of the Z And phenomenon.
