Allan,
meteors typically glow/vapourise between 90-30km altitude. If they survive, they will stop vapourising below 30km and fall to the ground dark.
Given the limitations of the speed of sound you won't hear anything, like a sonic boom, until a minute or two after the event.
Feel free to submit your report to the Facebook group Australian Meteor Reports where we attempt to determine a trajectory of meteors that we feel may be good candidates for meteorite falls.
Regards
David Finlay
