Daughter gets married in Sydney, can parents go?

As a daughter's parents, you can of course attend her wedding. Usually, parents are important participants in weddings. They witnessed and wished their daughter to enter the marriage hall at this important moment. But whether you can attend the wedding depends on local laws, wedding planning and personal circumstances. If Sydney is the city where you live or you can get a legal visa and meet the relevant travel requirements, you can usually attend your daughter's wedding. I suggest you communicate with your daughter in advance and pay attention to the changes of local laws and tourism policies in order to make the most accurate decision.
