Victoria government has just announced the Zero Emissions Vehicle (ZEV) Subsidy. $3000 for EV with purchase price below $68,740 (exclude stamp duty, and other charges).
No income test for this subsidy (can't see it on the website). Only 4,000 spots for this wave of subsidy.
P.S. if you buy a Model 3 SR+ (any colour), you will be eligible for the subsidy.
*** Update: my bad, even with Red colour it should still be below $68,740. So any colour is fine! ***
