Note a nice deep amplitude system peaking to the West of (SW) WA today. This shortwave frontal system is putting snow down to ~600m ASL on the same latitude as Melbourne, tomorrow. Albeit well west of WA in the IO. A follow-up system is due to offer the Bluff Knoll it's first chance of snowfall this year in the early hours of Wednesday AM. Snow down to ~1000m is possible IMO.
