Cameron McEvoy - (50m, 100m, 200m freestyle, relays): This budding astronaut may just emerge from the Rio pool as swimming's biggest star. Embroiled in the "Stilnox Six" controversy as a junior member of the infamous London 4x100m freestyle relay team. In Rio, McEvoy looks poised to make headlines for all the right reasons. First man to claim the freestyle triple crown at a national titles, winning 100m in the fastest time outside of the supersuit era and third fastest all-time. Will fill the void left by dual world 100m champion James Magnussen, who failed to qualify for an individual event.
Cate and Bronte Campbell - (50m, 100m freestyle, relays): Bronte Campbell emerged from her older sister's shadow at the 2015 world titles in Russia, becoming the third woman in history to complete the 50m-100m freestyle double. However, the real Cate Campbell will step up in Rio. Cate was recovering from major shoulder surgery at the 2015 titles but has reclaimed form that earned her the 2013 100m world title. Cate upstaged Bronte in the 50m and 100m at the Olympic trials, clocking a 100m winning time just 0.31 outside Britta Steffen's supersuit world record. The sisters should also inspire the 4x100m freestyle relay team who are Olympic defending champions.
Mitch Larkin - (100m, 200m backstroke, 4x100m medley relay): Unknown before the 2015 world titles, Larkin is now a marked man. Became the first male in 10 years - and just fourth ever - to claim 100m-200m backstroke double at a world titles in Russia last year. Also set a new 200m world short course record, becoming the first Australian to be named FINA Male Swimmer of the Year. Australia hasn't had an individual Olympic backstroke gold medallist since David Theile in 1960. The 22-year-old may change that.
Emily Seebohm - (100m, 200m backstroke): Ten years after making her first national team at 14, Seebohm is ready to dominate an Olympics. Became only the fifth woman in history - and first Australian - to claim the 100m-200m backstroke double at the 2015 world titles in Russia. Had a tearful last Olympic campaign. Broke the Olympic 100m record in London heats but relegated to silver by American nemesis Missy Franklin in the final by just 0.35. Blamed fixation with social media in emotional aftermath. Looks set to exorcise her demons after dominating Olympic trials.
Jared Talent - (20km and 50km walk): With justice finally served - albeit almost four years too late - Tallent will arrive in Rio as the defending 50km walk champion. Tallent will again contest both Olympic walks, but the longer event is clearly his strong suit.
Mat Belcher and Will Ryan - (470): Bidding to make it three gold medals in a row for Australia. Ryan replaced Malcolm Page after London. They won three world championships in a row before finishing third in terrible conditions in the most recent event in Argentina. Strong chance for gold.
Lauren Mitchell: A world champion on the floor in 2010, Mitchell is Australia's best ever chance of securing a first Olympic gold in gymnastics. Her routines on the floor and beam are among the best in the world, and it will all come down to her execution on the night.
Kim Brennan - (women's single scull): Unbeaten since 2014, two-time world champion single sculler Brennan (nee Crow) is Australia's best gold medal hope. The daughter of former AFL player Max Crow, Brennan was an elite hurdler before switching to rowing in 2005. Brennan achieved the rare feat of competing in two events at the London Olympics, winning a silver and bronze medal, but this time will channel all her energies into the single scull.
James McRae, Cameron Girdlestone, Sasha Belonogoff, Karsten Forsterling - (men's quad scull): Taking gold in the last two World Cup regattas heading into Rio, the men's quad scull will start favourites in Rio. Forsterling and McRae were part of the Australian crew that won bronze at the London Games. Their biggest threat will come from world champions Germany and Great Britain.
Anna Meares - (track sprint): Unlike London, where she beat arch-rival Victoria Pendleton for the sprint gold medal, Meares will go into Rio without being the reigning world champion in any of her three events. But the Australian camp is adamant she will be ready to fire.
Annette Edmondson - (track endurance): Edmondson was world champion last year in the omnium and team pursuit. She was hit by a car in training just before this year's worlds and did not win any medals, but should be a strong podium contender in her two events.
Shelley Watts - (60kg): Made history two years ago by becoming the first Australian to win a women's boxing gold medal at the Commonwealth Games, taking out the lightweight division. While the 60kg is stacked with talent, Watts is adamant she can win the gold medal. She's aiming to become Australia's first Olympic boxing medallist since Grahame "Spike" Cheney won silver in 1988.
Women's Rugby Sevens: Australia are gold medal favourites after romping to World Series glory in 2016 and they will be sweating on superstar Emilee Cherry overcoming a hamstring injury to lead the assault.
Men's Hockey: Australia's men's hockey team plans to hit Rio with all guns blazing, determined to turn Olympic bronze into gold. The Kookaburras have won bronze at the past two Games but ranked world No.1, they are determined to live up to their billing.
Women's water polo: Bronze medallists in London in 2012, the Australians are a strong chance to capture gold in Rio with defending champions the US their biggest threat.
