SYDNEY, NSW - JUNE 07:  A pregnant woman holds her stomach June 7, 2006 in Sydney, Australia. Australia is currently enjoying a baby boom, with the Australian Bureau of Statistics registering a 2.4% increase in births from 2004 to 2005, which represents the highest number of births since 1992. The Australian Federal Government has been encouraging people to have more babies, with financial incentives and the slogan by treasurer Peter Costello to 'have one for mum, one for dad, and one for the country'. The Federal Government has identified falling fertility rates and the ageing population as long-term problems for Australia's growth and prosperity.  (Photo by Ian Waldie/Getty Images)
