This candidate for the accreting-only symbiotic star was identified in the GALAH high-resolution spectroscopic survey (Munari et al., 2021). A reported orbital period of 459 days from Gaia data (Beck et al. (2023)), double in comparison with the period observed in photometry by Munari et al., 2021, suggests that the giant might be close to filling its Roche-lobe.
