I'm still relatively new from New Zealand, and I've been thinking about occasionally driving between Sydney and Melbourne as I have friends and family in both cities - going by plane is a bit expensive as I need to also factor in travelling to/from the airport to where I'm staying.
Is there anything I should be wary of in particular? I heard there were a lot of kangaroo road kills and should avoid driving during certain times. Also, are there any toll roads I should be aware of? Any information would be appreciated :)
There are a couple of different routes to consider, the deciding factor most likely how long you want to drive for.
Anywhere in Australia you will potentially find animals crossing roads at dawn and dusk. I've never seen any cross the Hume on the many times I've driven it.
If you are not familiar with driving long distances, or long durations, I'd recommend breaking up your trip with a stop-over.
