An investigation was underway on Thursday after four people were killed and two others seriously hurt when a light plane "fell out of the sky".
The six-seat, single-engine Piper crashed in relatively good weather late yesterday near a caravan park in northern New South Wales state.
While four people died, a father and his 13-year-old daughter miraculously survived when the plane came down less than one kilometre (0.6 miles) from Moree Airport, around 600 kilometres (372 miles) from Sydney.
"It looks like it's come in on the final approach to the airport and looks like, for whatever reason, it's just fallen out of the sky," local resident Lex Baguley told reporters, adding that there was no sign of fire on the aircraft.
Another witness told Brisbane's Courier-Mail newspaper the plane might have clipped a tree.
"It looks like they've clipped a tree because there's a tree broken and bent nearby," she said.
