In the Rugby Championship, South Africa aims to build on its decisive victory over Australia last week by fielding a modified squad featuring 10 changes, including two debutants. Coach Rassie Erasmus insists the changes do not reflect a lack of respect for the Wallabies, stressing the team's depth with 14 World Cup winners. Meanwhile, in the AFL, Geelong is vying for a top-four finish against St Kilda, having won six of their last seven matches, while both Gold Coast and Melbourne look to keep their slim finals hopes alive in their matchup. The GWS Giants face Fremantle in a crucial match, where a win would secure their finals spot, while Fremantle seeks to avoid falling out of the top eight. Each team is making strategic adjustments as the season approaches its climax, with various players returning from injury. The outcomes of these matches are pivotal for the standings in both competitions.
