Some good news here http://www.zdnet.com/article/turnbull-hands-out-first-batch-of-au8m-women-in-stem-funding/
The AU$3.9 million in funding will be spread across 24 organisations to roll out projects aimed at building interest in STEM for primary school age students, supporting post-graduates and women already pursuing STEM careers, and encouraging entrepreneurship among women.
Also there are some organisations that might be worth looking at in the article:
focuses on those aged 5-8 years with one-day events and online STEM and entrepreneurship training
offers 10-week workshops for young females
developing manufacturing and engineering-based careers for women in the local area
And Verco Engineering (although no site for that)
offers workshops for 1,000 year 9 and 10 students in regional SA
