No way there will be a draw.
Whatever Australia get England will bat in the same way at 5+ an over & set an achievable target with probably 1.5 days left.
Either Australia will make the target or they'll be bowled out.
England will not bat to eliminate the potential of losing the test.
Weather forecast is good for the rest of the test.
Whatever happens it'll be a great spectacle.

This is exactly how England will approach every test even if they are 0-4 going into the 5th.
