Barring monumental mishap, swim ace Emma McKeon will on Sunday collect an Australian record for most medals at the Olympic Games.
McKeon is red-hot favourite to win the 50-metres freestyle after setting an Olympic record when winning her semi-final.
And McKeon will be a key leg of Australia's women's 4x100m medley relay hunting gold on the final day of the swim program.
McKeon has nine career medals, equal with Ian Thorpe and Leisel Jones, as Australia enter Sunday with 10 gold, three silver and 14 bronze.
Rohan Browning will be the star turn at the athletics after winning his 100m heat in a lightning-quick 10.01 seconds on Saturday night to move to second spot on the Australian alltime list.
If the 23-year-old Sydneysider can replicate that effort in the semis on Sunday he is every chance of becoming the first Australian man since Hec Hogan in 1956 to contest an Olympic 100m final.
Reigning Commonwealth champion Brandon Starc is a legitimate medal shot in the men's high jump final beginning at 2010 AEST.

In the event for so long synonymous in Australia with the now-retired Sally Pearson, fellow Queenslander Liz Clay will be chasing a spot in the 100m hurdles final.
Sailor Matt Wearn only needs to finish the Enoshima course without disqualification on Sunday to confirm his gold-medal status in the Laser class.
It will be Australia's third successive Games atop the Laser podium, with Wearn succeeding Tom Slingsby (2012) and Tom Burton (2016) as Olympic champion.
Reigning world champion Logan Martin is also the man to beat in the medal round of the BMX freestyle, a new Olympic event.
He leads after Saturday's seeding rounds and is favoured to give Australian cycling its first Olympic gold medal since London, while Natalya Diehm is fifth out of nine riders in the women's event.
