A side trip into the Snowy Mountains (FANTASTIC in summer) would be a great option.
Agree totally ... last Christmas we drove back to Adelaide from Sydney following the coast the entire trip - lovely drive south of Sydney and then down around into Victoria.
Have also done the Snowys in summer and it is a really beautiful time of year there too.
If you don't have time to drive it - I'd just get the trip over and done with and fly.
