New Zealand can rise to seventh place in the Reliance ICC Test Championship table with a 2-0 win over Australia in the series that begins in Brisbane on Thursday.
A win in both Tests would earn the New Zealand 10 ratings points and move it above the West Indies. In that scenario Australia would drop level with Sri Lanka on 99 points but would remain in fourth position by a fraction.
A win for Australia in the series would close the gap on third-placed South Africa but would not be enough to move ahead of the South Africa.
