Hi Keane,
Apart from Sydney and Gold Coast, where does your tour take you?
Also, tell us the start/end dates and I am sure the local Clubs in the respective states you're visiting will let you know about their monthly meets, etc, which I am sure you'd be welcome to join in. They might not be up to date online yet (for March 2015 that is), but here is the QLD, NSW and Victoria club links.
