Basketball, athletics, tennis and the UniSport National Conference have all been impacted.

The UniSport National Conference, scheduled to take place at the University of Sydney on May 13 and 14, has been cancelled.

The organisation's Annual General Meeting will take place using technology to communicate, with the specifics yet to be announced.

Nationals Athletics - an event planned for April 3 to 5 at the University of Queensland - has been postponed.

Also postponed is the competition Pac 7 Tennis.

The University Basketball League, which has been due to begin on March 31, has been suspended for the time being.

Nationals 3x3 Basketball, a two-day tournament due to be hosted by the University of Canberra and begin on April 16, has been postponed.

As Nationals Swimming - beginning on May 14 - is not organised by UniSport Australia but Swimming New South Wales, a final decision has not yet been made public.

One event that can go ahead is Nationals League of Legends, which competitors play online.

It is planned for that competition to take place in April and May.

All events scheduled for June and beyond will continue as scheduled for now, a UniSport Australia statement said, with the merits of hosting such competitions to be re-evaluated at a later time.

"We encourage all student-athletes and members to continue to practice high standards in hygiene and should they feel ill with COVID-19 symptoms, to seek immediate advice from their doctor and follow government advice on self-isolation", the statement concluded.

Australia announced 75 new coronavirus cases today and anyone entering the country must self-isolate for 14 days.

Unlike much of the rest of the world, two of the country's biggest sports leagues - the Australian rules Australian Football League and rugby league's National Rugby League - are to carry on behind closed doors as things stand.

Gatherings of more than 500 people are banned as of today.
