There appears to be a limit to life - it isn't possible to have a high life expectancy as well as high fertility. Listed below are two ways that fertility can be increased in the current world "life" environment:
1. Cut life expectancy
2. Have a war and kill a lot of people (or organise a really big tsunami).
High fertility in comparison to life expectancy leaves everyone a bit 'short', destabilises populations and leads them into war. Lebanon was doing OK but it's life expectancy increased much faster than it's reproductive empowerment of women, and the other communities within it's borders and surrounds have reproductive policies which also don't empower women to manage the balance, keeping the whole region unstable.
Women know when they don't have the life resources to support a new child, and when reproductively empowered, can keep the balance. The Lebanese community in Australia has too many children for it's life expectancy and the surrounding population environment, and is unstable.
You should be very proud that Australian men and women respect the life balance (although men in power do it only reluctantly) - you shouldn't be pushing for higher fertility.
The demand for childcare and paid maternity leave is a sign that women are running short of life resources to manage their children, and the falling breastfeeding rate is also a signal. You need to give regard to these signals, and trust that the 'oldies' will get by just fine in the future!
