The 5th Ashes Test between Australia and England begins with Australia having already secured the series. Despite Australia's dominance, England has shown fight and had notable off-field moments. The pitch is expected to have grass, potentially aiding bowlers, but England needs strong performance to prove their recent win wasn't a fluke. Both teams face pressure, with Brendon McCullum's coaching future potentially on the line for England. Usman Khawaja is playing his final Test match.
