It's Day 4 of competition at the 2020 Tokyo Games and once again there is plenty of action to keep you enthralled.
After Kaylee McKeown claimed Australia's third gold in the pool, attention now turns to kayak star Jessica Fox and mountain biker Bec McConnell and their individual quests for gold.
Later tonight the Opals start their Olympic campaign, while the Matildas face the might of the USA in the women's football. Speaking of tough assignments, having scraped through to the quarterfinals despite a narrow loss to New Zealand, Australia's men's sevens team face Fiji also on Tuesday night.
Read on for rolling coverage of Australia's efforts at the Olympics:
Matildas await results after draw with United States
Tony Gustavsson's Matildas held world No.1 United States to a nil-all draw in their final match of Group G, but now await other results to find out if they've qualified as best third-placed team.
The draw saw the United States progress to the quarterfinals, but they were left to rue a disallowed goal by VAR after forward Alex Morgan found the back of the net.
Opals fade in Olympics opener against Belgium
The Australian Opal let a seven-point lead slip, fading badly in a 85-70 loss to Belgium in their Olympic Games opener.
They'll look to bounce back in their next match against China on Friday.
Australia's hopes in men's Sevens gone
Australia's men will miss the medals in Tokyo after their attempts to crack Fiji's defence proved futile in a frustrating 19-0 rugby sevens quarter-final loss.
After sneaking into the final eight, the inconsistent Australian side had every chance of pulling off an upset against the defending Olympic champions on Tuesday when they trailed 7-0 with three minutes to play.
But they were unable to trouble defending champions Fiji.
Heartbreak for Fox as gold goes begging
Australia's Jessica Fox has come away with a bronze medal following a shock upset in the women's kayak final on Tuesday afternoon.
Fox was near faultless in her semifinal run, finishing with a time of 103.85 seconds despite a two-second penalty, which was good enough to move past Elishka Mintalova and into the gold medal position ahead of the 10-woman final.
But the 27-year-old was hit with two penalties to complete her run in a time of 106.73. Germany's Ricarda Funk finished at 105.50 to claim gold, while Spain's Maialen Chourraut came in second.
Fox will have to wait for Paris 2024 to complete the full set of Olympics medals having won silver in London and bronze in Rio.
Wright creates Australian surfing history
Owen Wright has won Australia's first ever Olympic surfing medal, taking bronze in a thrilling duel with Brazilian Gabriel Medina.
Wright, who suffered a devastating injury that almost forced him to quit the sport earlier in his career, triumphed with a score of 11.97, eclipsing his Brazilian opponent's 11.77.
Osaka exits in third round
The upsets keep on coming in the women's singles tennis, with local favourite Naomi Osaka following Ash Barty out of the competition.
After the Australian was beaten in her opening round, Osaka, who lit the Olympic cauldron on Friday night, was beaten by Czech woman Marketa Vondrousova 6-1 6-4 in the third round on Tuesday.
Meanwhile, Australia's medal hopes in tennis will come down to Ash Barty and Sam Stosur's doubles teams after James Duckworth was the last to be eliminated from singles.
Duckworth was knocked out by Russian heavyweight Karen Khachanov 7-5 6-1 in the second round.
Gold for Australia! McKeown wins 100m backstroke
Kaylee McKeown has won Australia's third gold medal in Tokyo, taking out the women's 100m backstroke with a flying second 50m.
McKeown finished ahead of Canadian Kylie Masse and the United States' Regan Smith in an Olympic record time of 57.47.
"F--- yeah," an overjoyed McKeown told Channel 7 after her victory, before quickly apologising for her language.
Fellow Australian Emily Seebohm, at her fourth Olympics, finished fifth.
McKeown's triumph is Australia's third gold of the Games, following the women's 4x100m freestyle relay and Ariarne Titmus in the 400m freestyle.
It is also the 200th medal won by Australia's women at the Olympics.
Australia's other medal hope in the pool on Tuesday, Mitch Larkin, finished seventh in the men's 100m backstroke final.
Olympian Giaan Rooney earlier posted a picture to social media of a young McKeown alongside her idol Seebohm, highlighting the special relationship between the two swimmers.
Chalmers cruises to 100 freestyle heat win
A restrained Kyle Chalmers has fired the first shot in defence of his Olympic 100-metres freestyle crown.
The Australian breezed to victory in Tuesday night heats at the Tokyo Games as American challenger Caleb Dressel and Italian flier Thomas Ceccon also impressed.
Ceccon was quickest through the heats in 47.71 seconds followed by Dressel (47.73) and Chalmers (47.77).
He'll return to the pool for a semi-final on Wednesday, as will teammate Brianna Throssell, who was ninth-fastest through the 200m butterfly heats.
Zac Stubblety-Cook evidenced his medal prospects in the men's 200m breaststroke with a standout swim in the heats, clocking 2:07.37 to dead-heat with Arno Kamminga from the Netherlands.
Australia's 4x200m freestyle relay team of Alexander Graham, Mack Horton, Elijah Winnington and Zac Incerti were second-quickest in heats, with Great Britain almost two seconds clear of the field.
Titmus and Ledecky book another showdown
Four hundred metre freestyle gold medallist Ariarne Titmus has booked another date with American Katie Ledecky.
After their epic 400m battle, the pair won separate 200m freestyle semifinals on Tuesday.
Titmus could become the first Australian woman since the great Shane Gould in 1972 to take the golden double in the 200m and 400m freestyles.
The Australian, a day after winning the 400m and swimming a 200m heat, kept herself in check for three laps before steaming to semifinal victory in one minute 54.82 seconds.
"I felt a little bit sluggish which was understandable," Titmus said. "It was just about trying to execute a good race."
Kookaburras in ominous form
The Kookaburras have underlined their gold-medal credentials while crushing reigning Olympic champions Argentina 5-2 in Tokyo.
World No.1 Australia started these Games with a surprisingly tough 5-3 victory over Japan, but the gold-medal favourites have backed up a 7-1 smashing of India with yet another dominant display.
The victory ensures the Kookaburras, seeking redemption after a quarter-final loss at Rio de Janeiro marked the first time they missed the Olympic podium since 1988, are on track to top Pool A.
Aussies stun water polo powerhouse Croatia
Australia have secured a major scalp and their first win of the Tokyo Olympics men's water polo tournament, upsetting powerhouse Croatia 11-8 in a topsy-turvy struggle.
Richard Campbell and Blake Edwards scored a combined five goals, while goalkeeper Anthony Hrysanthos led a brilliant defensive effort that was also central to Australia's first win over Croatia in Olympic history.
The Sharks, desperately needing to bank points given their pool features three of the top four sides from Rio 2016, shot out to a 7-3 lead early in Tuesday night's third quarter.
Croatia, silver medallists at the 2016 Games after winning gold at London 2012, rallied to reduce that buffer to just 7-6 at three-quarter time.
The third term ended with a contentious call that denied Edwards, representing the Sharks at these Games alongside brother and teammate Lachlan, a buzzer-beating goal.
Officials reviewed footage of the final seconds before ruling that time elapsed before Edwards scored.
The camera captured Australia coach Elvis Fatovic, who competed for Croatia at the 2000 and 2004 Olympics then served as an assistant coach for their triumph at the London Games, seeking clarification in direct fashion at the break.
Fatovic's charges weren't rattled, lifting when it mattered most while showing impressive composure in the final quarter.
Edwards nailed consecutive late goals, fashioning a 11-7 lead with a tick under three minutes remaining in the match.
Australia, who lost 15-10 in their tournament opener against Montenegro, currently sit second in Group B as they prepare to face reigning Olympic champions Serbia on Thursday night.
