England's women's cricket team forced a draw against Australia to keep their Ashes hopes alive.
Australia would have retained the trophy if they had won the inaugural day-night Test on Sunday, 12 November.
England began on 40-0, 128 runs behind, but after losing their openers, Knight (79 not out) added an unbroken 117 with Georgia Elwiss (41 not out) to keep Australia at bay before a draw was agreed with the tourists on 206-2.
Australia now lead the series 6-4 on points, meaning - barring intervention from the weather - England need to win all three Twenty20 internationals in order to regain the Ashes trophy.
The T20 series begins on Friday, 17 November, at the same ground in Sydney.
