Tropical cyclone warning centres are located in these cities as they are the major centres along the coasts where most cyclones occur. Cyclones rarely hit as far south as Perth, but Perth is the capital of Western Australia, and the centre for communications - thus it is a logical location. Brisbane is in a similar situation. Darwin is right in the middle of cyclone territory.
A cyclone watch is similar to a hurricane watch. A cyclone is an extra-tropical storm that occurs over the ocean. These storms are labeled differently in various parts of the world. With any weather system, a watch means that conditions are favorable for development. A warning means that a threat is imminent.
A tropical cyclone will affect the locality.Winds of 30-60 kph may be expected in at least 36 hours or intermittent rains may be expected within 36 hours. (When the tropical cyclone develops very close to the locality a shorter lead time of the occurrence of the winds will be specified in the warning bulletin.)

Typhoon Haiyan.Tacloban, in Leyte province was hit by the tropical cyclone Haiyan, in November 2013, the strongest typhoon on record.Based on the estimate by the US military's installation on Hawaii, the Joint Typhoon Warning Centre, it was the most powerful recorded cyclone ever to make landfall. It hit the Philippines with sustained winds of 305km/h to 315km/h.

The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) releases tropical cyclone warnings in the form of Public Storm Warning Signals (PSWS) An area having a storm signal may be under:PSWS #1 - Tropical cyclone winds of 30-60 km/h are expected within the next 36 hours. (Note: If a tropical cyclone forms very close to the area, then a shorter lead time is seen on the warning bulletin.)PSWS #2 - Tropical cyclone winds of 60-100 km/h are expected within the next 24 hours.PSWS #3 - Tropical cyclone winds of 100-185 km/h are expected within the next 18 hours.PSWS #4 - Tropical cyclone winds of greater than 185 km/h are expected within 12 hours.
A blue cyclone flag indicates a cyclone has formed and may affect the area within 48 hours. Yellow alert flags indicate that the cyclone is 24 hours out. Red alert indicates that the destructive winds are forecast in the next 6 hours and immediately take shelter.

Tropical cyclones cannot be managed or prevented, so the only recourse is to warn people, prepare communities and put programmes into effect to clean up afterwards. Tropical cyclone warning systems are in place within cyclone-prone countries such as Australia. The Australian Bureau of Meteorology keeps residents informed on the development, current and predicted movements and progress of a cyclone. Communities in cyclone-prone areas in developed countries like Australia make use of technology to construct buildings which can better withstand cyclonic effects. This has particularly been the case since Cyclone Tracy blew away most of the city of Darwin in 1974. Emergency services are better prepared nowadays, while the media and websites keep the public well informed of how to prepare their homes and properties before cyclones and what to do once a cyclone hits.
Yes, a number of warnings were given. The cyclone had been tracked for a few days before it hit Darwin.

you should go in your basement and hide under a heavy object.
A tropical depression is not a tropical storm, but can easily develop into one. Additionally, a tropical depression can still be hazardous, as the heavy rains can lead to flooding.
