Head out of Melbourne through Cranbourne, keep going through towards Phillip Island, don't go to Phillip island - you must turn off on the A440 to Korumburra and Leongatha, go through both of these towns.
Go past Koonawarra Store approximately 2 to 4 km and turn at Tarwin North (no town) towards Tarwin Lower (Clearly Signed Tarwin Lower/Venus Bay).
