Logan City Council, Queensland, Australia. The City of Logan is ideally located between Brisbane, Ipswich and the Gold Coast, and has easy access to the national highway and rail networks. It has thriving light industrial precincts at Marsden, Crestmead, Slacks Creek and Loganholme, which are continuing to expand to meet the demand of quality, responsible industry. Logan is home to more than 300,000 people from more than 185 different cultures. We celebrate our diversity and the rich and varied lifestyle it offers. Logan is also a very young city with around 50 per cent of residents aged 30 or younger. This adds energy and enthusiasm to our community and gives us a real vibrancy. No wonder we have become known as one of the most diverse cities in Australia.
