I bought a 200W third-party laptop charger online and want to know whether it's safe. I'm in Australia, where electrical products have fairly strict safety requirements. After leaving the charger plugged in all day, I noticed that it became hot. Could that be normal, or is it a sign that the charger might damage my laptop or create a fire hazard?

There isn’t enough information to judge this specific charger. Check that its output voltage, connector, and charging standard match your laptop, and look for a genuine Australian RCM mark rather than just vague claims about being certified. A reputable manufacturer with clear specifications and good reviews is much safer than an anonymous bargain-brand unit.
Some warmth is normal because chargers convert mains electricity and waste some energy as heat, especially when they’re working hard. Stop using it if it becomes too hot to comfortably touch, smells like burning plastic, makes unusual noises, has damaged cables, or shows discoloration. If the charger lacks a verifiable RCM certification or comes from an unknown seller, replacing it with a reputable certified model is the safer choice.
A 200W rating is the maximum the charger can provide, not power that it constantly forces into the laptop. The laptop normally negotiates for the voltage and current it needs, so a higher wattage rating by itself usually isn’t dangerous. However, a poorly designed or counterfeit charger can still fail, overheat, damage equipment, or cause a fire.
