Australia vs Bangladesh 1st Test: Day 4 Wrap BANGLADESH'S BIGGEST EVER WIN

Bangladesh have produced one of the biggest upsets in Australian Test cricket history, defeating Australia by nine wickets in Darwin to take a 1-0 series lead.

Menners reflects on Bangladesh's remarkable performance, Mahedi Hasan's five-wicket haul and Hassan Mahmud's nine wickets, while Cameron Green's century provides Australia's only real positive from a disastrous Test.

The big question now is what happens to Australia's top order. Should Jake Weatherald and Marnus Labuschagne be dropped? Is it time for Matt Renshaw to return? And does Nathan Lyon deserve to retain his place?

Menners also asks whether this defeat is simply a shock one-off — or the beginning of a major turning point for an ageing Australian side.
