The Australian Boomers are back in action on day 5, while Ariarne Titmus goes up against rival Katie Ledecky once again in the pool.
The Olyroos also return to the field as they fight for a place in the next round of the competition.
The Tokyo Olympics are broadcast in Australia on free-to-air TV on Channel Seven, as well as streaming platform 7Plus.
The ABC will be live blogging events every day of the Olympics.
Here are the events to watch on Wednesday, July 28.
Swimming: Titmus v Ledecky 2.0
The rivalry continues when Ariarne Titmus takes on American Katie Ledecky once again in the women’s 200m freestyle final at 11:11am.
After Titmus stormed home to win in a thrilling 400m freestyle final, she then qualified fastest for the 200m final with a time of 1:54.82.
Ledecky will also compete in the Olympic’s first-ever women’s 1500m freestyle final at 12:24pm after qualifying fastest on Monday night.
Australians Maddy Gough and Kiah Melverton will be in lanes 1 and 8 for the final after scraping into the top eight.
Football: Olyroos take on Egypt
The Olyroos will be fighting for a place in the next round of the competition when they take on Egypt in their final men’s group C match at 8:30pm.
After pushing Spain for 80 minutes in their last game, the Australian side eventually went down 1-0 in their second group game.
But that came after a stunning 2-0 win over Argentina with goals to Lachlan Wales and Marco Tilio.
It places the Olyroos in second position in their group, but they’ll need to take at least a point from their clash against Egypt to progress.
Basketball: Boomers back on court
Fresh from a comfortable win over Nigeria in their first game of the campaign, the Australian Boomers take on Italy next at 5:50pm.
Patty Mills was the star last time out, dropping 25 points, while Joe Ingles and Dante Exum were next best with 11-points apiece as the Boomers won 84-67.
Italy come into the match after a solid victory over Germany, winning 92-82 on Sunday.
Simone Fontecchio top-scored for the Italian side with 20-points while Stefano Tonut and Atlanta Hawks forward Danilo Gallinari had 18 points each.

If it seems like the athletes at the Tokyo Olympics look younger than ever, you might be onto something. So far in Tokyo, 19 athletes with an age starting with “1” have won medals, including 13 individuals and 6 team members. And there looks like more to come shortly.
Today, 18-year-old Tunisian Ahmed Hafnaoui will be going for his second gold medal of the Olympics, in the 800m freestyle.
On the range, 17-year-old South Korean Kim Je-deok will be marching towards his third gold medal of the Olympics — looking to become the first ever triple gold medallist in archery at a single Olympics.
Kim is aiming to join an elite club of 22 under-18 triple gold medallists. He would be the first since Missy Franklin in 2012, and the first ever outside of swimming and gymnastics.
The first running of the women’s street skateboard final also broke a longstanding Olympic record.
As a group, the three on top of the dias represented the youngest combined Olympic podium ever.
At just 13 years and 330 days old, gold medalist Momiji Nishiya was the fourth youngest Summer Olympic gold medalist ever, and silver medallist Rayssa Leal was the fifth youngest silver medallist at 13 years and 203 days old.
The only younger winner in a solo sport was Marjorie Gestring in the 3 metre springboard diving at the Berlin Olympics in 1936.
It begs the question: What if we only counted the medals of those younger than 20 years old?
All time, the USA and Russia have provided the most young medal winners. Australia is well represented in third, ahead of China and both Germanys.
Household names like Shane Gould, Ian Thorpe, Murray Rose and Betty Cuthbert won medals as teenagers, and they’re joined in Tokyo by Mollie O’Callaghan and Meg Harris in the 4x100m freestyle relay.
