This is a large, brown dragonfly with yellow markings and some black.
Around Melbourne they can usually be found near lowland rivers during summer and early autumn.
I've watched them fly fairly low over slow sections of the Yarra, occasionally hovering briefly.
Eggs are deposited on fallen timber in water, as can be seen in the first photo.
Although similar to some other Austroaeschna species, including
Austroaeschna inermis and Adversaeschna brevistyla,
its patterns of lines and spots on the side of the thorax is distinctive.
