For those didn’t quite get around to putting in a proposal for
linux.conf.au 2020 (Gold Coast, January 13 to 17), there’s
another chance: the proposal deadline has been extended to August 11.
“We have heard that some of you would like a bit more time to submit your
proposals for linux.conf.au 2020. So, we have decided to extend the due
date by two weeks to help everyone have a chance to submit.“
