The highlight of the event though was a panel where schoolchildren were given the chance to interview three astronauts. We've got the audio so you can listen in.
The panel included Paul Scully-Power, Australia’s first-ever astronaut, who went to space in 1984; Eric Philips, who only blasted off to space on a private SpaceX mission in April; and Katherine Bennell-Pegg, the first astronaut to formally qualify under the Australian flag.
