With online classes keeping some students off campus, and training unable to resume due to COVID-19, it has led to a reduction in original team numbers from those submitted by the club earlier this year.

CSU could end up fielding as few as five teams when the season gets underway.

It's a far cry from their original plans but a drop in numbers shouldn't be confused for a drop in enthusiasm among the university's ranks.

Numbers in the club's higher grades are still as strong as ever, and it gives CSU belief that when the first grade Stags and Vixens get onto the field they'll be a force to be reckoned with.

Club captain Brady Evans said there's still plenty of excitement around the club for the season ahead, which is expected to start in July.

"It's still subject to change depending on what the uni does with classes. We originally had five men's and four women's teams but that's been reduced to probably three men's and two women's teams," he said.

"We were concerned that we'd even get on the park at all. But to have a lot of quality players still here is positive for the season ahead.

"In first grade ladies we lost maybe half that side. We had quite a few graduate or move out of town, which is something that happens a lot at a uni club. There's been some more than handy replacements.

"On the men's side of things we've had an influx of some really nice players, which is great because it's something we've needed. We had a gun side three and four years ago and we've been able to refill those stocks now."

CSU snuck in some trial matches back in March before the coronavirus brought everything to a halt.

There's no resumption to training in sight just yet, so Evans said the club's been doing their best to keep everyone focused and motivated.

"We were only together for training for three weeks before trials, then this all got underway. Since then we've had to do our own thing individually," he said.

"We're just doing small kickarounds, keeping social distancing, and I know in the second grade team our coach gave us instructions for running at home and keeping fit.

"I think a lot of that stuff has been happening across all our teams so the onus is on the individual to keep their fitness up for when the season gets underway."

One thing helping the club bond during a tough time has been their push up challenge to raise money for Headspace.

Some club members are aiming to do more than 3,000 push ups over the space of three weeks.

"Originally we only had a handful sign up but we had a late drive," Evans said.

"There were a few keen to do the full 3,046 pushups by themselves and others, like myself, who were just excited to get the word out."

Another boost to CSU's club morale will be the resumption of training this week.

Football NSW have allowed limited training to get back underway after the state government's latest round of restrictions being eased.
