What cultural faux pas should I try to avoid making in Port Douglas?

"In Port Douglas, it's important to respect the local customs and traditions. Avoid making derogatory comments about the country, its people, or its culture. Australians are known for their friendly and laid-back nature, so avoid being overly formal or pretentious. It's also considered rude to not wait your turn in line or to push ahead of others. Australians value fairness and equality, so try to treat everyone with respect and kindness. Avoid littering or disrespecting the environment. Australia is known for its beautiful natural landscapes and Australians take pride in preserving their environment. Do not make light of Australia's history with its Indigenous people. This is a sensitive topic and should be approached with respect and understanding. Avoid making jokes about dangerous animals or natural disasters. These are serious issues in Australia and are not taken lightly. Lastly, tipping is not customary in Australia, so do not feel obligated to leave a tip at restaurants or for services. However, if you feel the service was exceptional, a tip would be appreciated," remarked another expat in Port Douglas, Australia.
