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

"In Wollongong, it's important to respect the local customs and traditions. Avoid making derogatory comments about Australia, its culture, or its people. Australians are generally laid-back but they take pride in their country and culture. Australians value punctuality, so try not to be late for appointments or meetings. If you are running late, it's considered polite to call and let the person know. Avoid discussing sensitive topics such as politics, religion, and race unless you know the person well. Australians are generally open-minded, but it's best to avoid potentially offensive topics. Do not litter or disrespect the environment. Australians are very conscious about preserving their natural surroundings and take environmental issues seriously. Australians are known for their love of sports, particularly rugby and cricket. Even if you're not a fan, it's best not to criticize or belittle these sports. Avoid being overly formal. Australians are generally informal and prefer to use first names in most situations, even at work. Do not jump queues or push in line. Australians are very respectful of queues and it's considered rude to not wait your turn. Avoid making loud or obnoxious noises in public places. Australians value their peace and quiet, especially in places like restaurants or public transportation. Lastly, tipping is not mandatory in Australia. Service staff are paid a decent wage and do not rely on tips. However, if you feel the service was exceptional, feel free to leave a tip," remarked another expat who made the move to Wollongong, Australia.
