KEY POINTS:
New figures show Australia has had its biggest baby boom since the early 1980s.
The Australian Bureau of Statistics (ABS) says 135,000 babies were born in the past six months, which is the highest number since records started 25 years ago.
More migrants also arrived during the period, boosting population growth by 1.3 per cent.
Commsec strategist Martin Arnold says Australia's tight labour market and economic growth have encouraged people to have more children.
"It reflects the fact that consumers feel financially secure and when the mums come back to the market, they'll be able to get a job pretty easily," he said.
"A range of sectors are going to benefit from this.
"Not just retail spending, but also the housing sector and obviously child care has been a sector of importance recently and demand for that is only going to grow in the future."
