I agree with Callistemon. Australia has a more relaxed culture than the UK, and the climate lends itself to year round outdoor lifestyles, which suits many families - work doesn’t dominate people’s lives in the same way as here, they may work longer hours if they were part time here, but evenings are long and warm for the majority of the year.
My sister and her husband emigrated 30 years ago, when their children were small, and have never regretted the decision. Technology has made contact with family much easier in recent years, and in normal times family visit them, and they come home every couple of years for a few weeks at a time (they have a brilliant long service award holiday system). My brother in law jokingly calls their house Sponge Cottage as we are all so keen to visit - and when people go out there they stay for a few weeks at a time, so time together lost is regained, I don’t think the children missed out, they are as much part of the family as the rest of us.
