Roundtrip Australia

Hey guys. Planning a round trip to Australia next year. Since most stopover flights go via Dubai, Abu Dhabi or Singapore, you could maybe even spend 1-2 days in one of the cities beforehand. I would find Singapore the most interesting. In addition, one could counteract so also better against the jet lag. Afterwards we would fly to Perth and stay there for about 5 days or explore the surroundings (e.g. Pink Lake). So with the rental car that should not be a problem. After that we would fly to the east coast. There we would also rent a car so that we can drive down the coast from Brisbane to Melbourne. So first stop would be Cairns. There we would spend about 5 days. Among other things we would visit the wonderful Great Barrier Reef. Afterwards we drive or fly to Brisbane. Since the trip takes about 20 hours, we could think about a flight. But I am flexible. From Brisbane we will have a rental car. Since we will spend there about 5 days and then drive down to Sydney. I think the drive along the coast is breathtaking. After we have experienced 5 days in Sydney we will go to the last station. Namely Melbourne. There are also another 5 days planned. Back you could of course book a stopover flight and this time spend a few days in Dubai. Or alternatively, you could fly to New Zealand if you have the time and desire to do so, and spend a week there exploring the area. It is important to me that everyone can bring in his wishes. The dates are also flexible and if someone still has wishes we see if we can accommodate it. This trip is a lot of activities is called so rather an active vacation. Culture, country, city, party and of course there will also be enough time to relax on the beach.
