Didn’t realize how big Australia was until arriving. Rented a car and drove from Sydney to Melbourne along the coast (amazing rock formations.. the apostles?..) then up to Ayres Rock (sunrise was awesome, the rock appears to change colors), then back to Sydney.. over 5,000 miles on the car in 7 days. Then spent three weeks leisurely going up the east coast. Divers, check out South West Rocks.. a small spot north of Sydney with a cool cave dive.
