Goiania, as with every city, has areas that are safer than others. Its bustling daytime atmosphere can feel welcoming and safe but at night it's sensible to be cautious. Common precautions like not displaying expensive belongings, staying in populated areas, avoiding late-night walks, and using credible taxi services are recommended. Scams, pickpocketing and thefts can occur, particularly in tourist-heavy areas. So while it's not considered extremely dangerous, it's not considered extremely safe either. It's somewhat in the middle. As always, alertness and awareness are key to your personal safety when traveling.
