* The ships were overcrowded and unsanitary, and disease spread quickly.
* The food was often spoiled or inadequate, and many people suffered from malnutrition.
* The weather was often rough, and the ships were often battered by storms.
* Many people died from accidents or injuries.
* The voyage to Australia took about eight months, and many people were sick or injured by the time they arrived.
Here are some specific examples of the conditions on the First Fleet:
* The ship "Scarborough" was so overcrowded that people were forced to sleep in shifts.
* The food on the "Charlotte" was so bad that people were reduced to eating rats and cockroaches.
* The ship "Sirius" was caught in a storm that lasted for several weeks, and many people were injured or killed.
* The ship "Alexander" was wrecked on a coral reef, and all of the people on board drowned.
In total, about 20% of the people who sailed on the First Fleet died during the voyage to Australia.
Despite the harsh conditions, the First Fleet was a success. The ships arrived in Australia in January 1788, and the colony of New South Wales was founded. Australia is now a thriving country with a population of over 25 million people.
