Tasmania JackJumpers captain Clint Steindl believes his coach and NBL teammates have done the right thing in calling out "ugly" online abuse.

At a post-game press conference on Saturday, coach Scott Roth said players, their wives and children had been brutally attacked on social media.

He said one person wished a miscarriage upon a player's pregnant wife.

Basketball Australia and the NBL are investigating the allegations and have pledged to provide updates in due course.

"Basketball Australia have a zero tolerance for any abuse directed at any person," the organisation said in a statement.

JackJumpers, who won the championship last season, have had a tough start to 2024/25 but got off the bottom of the table with an upset win over the New Zealand Breakers on Saturday.

Captain Clint Steindl said social media abuse was a problem across the NBL and sport in general.

"I'm proud of the guys and the fact they've brought it up and brought light to the issue," he told reporters on Wednesday.

"Hopefully (we) put some things in place to eradicate it.

"You're a public figure, you're going to receive criticism to some level (but) when you bring family and children into it, it is right out of line."

Roth has called for the NBL to be more proactive in monitoring online abuse, describing recent comments as ugly.

Getting players to leave social media wasn't the answer, Steindl said.

"If athletes went off social media, people wouldn't be as invested (in the sport)," he said.

"Athletes make it what it is and you want them to show their true colours."

An emotional Roth said families had been left distraught and some were too scared to leave their home, but the club was determined to stick together.

"We've got a tight-knit group. We have plenty to focus on within these four walls at practice," Steindl added.

"With the success we've had, we're now the hunted.

"When you don't get the results you want, people are going to come after you and there is going to be some negativity."

The second-last JackJumpers (4-8) have the opportunity for back-to-back wins when they host the third-last Brisbane Bullets in Hobart on Friday night.

Final calls on whether injured Olympian Will Magnay (shoulder) and Sean MacDonald (ankle) return will be made later in the week, but Steindl was hopeful the pair would play.
