The population is growing quite rapidly, and has quadrupled since the end of WWI. Still, given the size of the country, the population density is actually among the lowest in the world. While there are many people scattered throughout Australia, the cities naturally have the largest populations. The current population is 22.68 million and growing. They feel that by the year 2050, the population could be as high as 42 million. With such a large and growing population, the need for people who have skills in electronic engineering will grow as well. It could be a great field to start getting into right now.
