ARC says they’ll announce DECRA and LIEF outcomes tomorrow (Tuesday 25th Nov).
In recent times these announcements have been around 11am Canberra time. With 2 schemes on the same day, I assume they’ll announce one of them later in the day (probably DECRA first).

A new gravitational wave event rocked detectors almost 10 years after the first detection. But this time, it was up to four times as loud thanks to a decade of upgrades.

Scientists detect biggest ever merger of two massive black holes
Ripples in space-time from collision recorded by gravitational wave detector forces a rethink of how the objects form
Scientists have detected ripples in space-time from the violent collision of two massive black holes that spiralled into one another far beyond the distant edge of the Milky Way.
The black holes, each more than 100 times the mass of the sun, began circling each other long ago and finally slammed together to form an even more massive black hole about 10bn light years from Earth. Continue reading...
